-NOFX is an open-source trading terminal where the strategy is a language model. Each trader runs a continuous loop — read market structure, decide, execute, record the reasoning — while a Go runtime clamps every order to hard risk limits the model cannot override.
+## AI-Powered Multi-Asset Trading Platform
 
-Traders compose freely: any model, any of nine exchanges, any strategy. Run several side by side and compare them on a public leaderboard by realized return. Everything runs on your own machine; exchange credentials are encrypted at rest and never leave it.
+**NOFX** is an open-source AI trading system that lets you run multiple AI models to trade automatically. Configure strategies through a web interface, monitor performance in real-time, and let AI agents compete to find the best trading approach.

+## Quick Start
+
+### One-Click Install (Local/Server)
+
+**Linux / macOS:**
 ```bash
 curl -fsSL https://raw.githubusercontent.com/NoFxAiOS/nofx/main/install.sh | bash
 ```
 
-The terminal opens at `http://127.0.0.1:3000`.
+That's it! Open **http://127.0.0.1:3000** in your browser.
 
-**First run**
+### One-Click Cloud Deploy (Railway)
 
-1. Register — the first account becomes the owner of the instance.
-2. Follow the guided launch: put **$1+ USDC** (Base network) in the AI fee wallet it creates for you, then connect Hyperliquid and deposit **$12+ USDC** to trade with.
-3. Start **Autopilot**. The AI scans the market every few minutes and trades on its own; every decision appears on the dashboard as it happens. Stop it anytime with one click.

-## The model proposes. The runtime disposes.
-
-Decisions come from a language model reading the [Claw402.ai](https://claw402.ai) · Vergex data stack: a live signal board that ranks every market with directional bias and signal strength, per-symbol Signal Lab deep signals, cost-basis and liquidation heatmaps that show where the crowd's fuel and walls sit, and real-time market net flow — cross-checked against raw candles and the trader's own live track record. Execution does not.
-
-Every order passes through limits enforced in code, outside the model's reach:
-
-|                          |                                                                                    |
-| :----------------------- | :--------------------------------------------------------------------------------- |
-| Position limits          | Max concurrent positions, notional capped as a ratio of equity, one position per symbol |
-| Leverage clamps          | Hard caps applied at order-sizing time, independent of what the model requests     |
-| Exchange-side protection | Stop-loss and take-profit placed on the exchange immediately after every entry     |

+
+---
+
+## Windows Installation
+
+### Method 1: Docker Desktop (Recommended)
+
+1. **Install Docker Desktop**
+   - Download from [docker.com/products/docker-desktop](https://www.docker.com/products/docker-desktop/)
+   - Run the installer and restart your computer
+   - Start Docker Desktop and wait for it to be ready
+
+2. **Run NOFX**
+   ```powershell
+   # Open PowerShell and run:
+   curl -o docker-compose.prod.yml https://raw.githubusercontent.com/NoFxAiOS/nofx/main/docker-compose.prod.yml
+   docker compose -f docker-compose.prod.yml up -d
+   ```
+
+3. **Access**: Open **http://127.0.0.1:3000** in your browser
+
+### Method 2: WSL2 (For Development)
+
+1. **Install WSL2**
+   ```powershell
+   # Open PowerShell as Administrator
+   wsl --install
+   ```
+   Restart your computer after installation.
+
+2. **Install Ubuntu from Microsoft Store**
+   - Open Microsoft Store
+   - Search "Ubuntu 22.04" and install
+   - Launch Ubuntu and set up username/password
+
+3. **Install Dependencies in WSL2**
+   ```bash
+   # Update system
+   sudo apt update && sudo apt upgrade -y
+
+   # Install Go
+   wget https://go.dev/dl/go1.21.5.linux-amd64.tar.gz
+   sudo tar -C /usr/local -xzf go1.21.5.linux-amd64.tar.gz
+   echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc
+   source ~/.bashrc
+
+   # Install Node.js
+   curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
+   sudo apt-get install -y nodejs
+
+   # Install TA-Lib
+   sudo apt-get install -y libta-lib0-dev
+
+   # Install Git
+   sudo apt-get install -y git
+   ```
+
+4. **Clone and Run NOFX**

+   ```bash
+   curl -fsSL https://raw.githubusercontent.com/NoFxAiOS/nofx/main/install.sh | bash
+   ```
+
+---
+
+## Server Deployment
+
+### Quick Deploy (HTTP via IP)
+
+By default, transport encryption is **disabled**, allowing you to access NOFX via IP address without HTTPS:
+
+```bash
+# Deploy to your server
+curl -fsSL https://raw.githubusercontent.com/NoFxAiOS/nofx/main/install.sh | bash
+```
+
+Access via `http://YOUR_SERVER_IP:3000` - works immediately.
+
+### Enhanced Security (HTTPS)
+
+For enhanced security, enable transport encryption in `.env`:
+
+```bash
+TRANSPORT_ENCRYPTION=true
+```
+
+When enabled, browser uses Web Crypto API to encrypt API keys before transmission. This requires:
+- `https://` - Any domain with SSL
+- `http://localhost` - Local development
+
+### Quick HTTPS Setup with Cloudflare
+
+1. **Add your domain to Cloudflare** (free plan works)
+   - Go to [dash.cloudflare.com](https://dash.cloudflare.com)
+   - Add your domain and update nameservers
+
+2. **Create DNS record**
+   - Type: `A`
+   - Name: `nofx` (or your subdomain)
+   - Content: Your server IP
+   - Proxy status: **Proxied** (orange cloud)
+
+3. **Configure SSL/TLS**
+   - Go to SSL/TLS settings
+   - Set encryption mode to **Flexible**
+
+   ```
+   User ──[HTTPS]──→ Cloudflare ──[HTTP]──→ Your Server:3000
+   ```
+
+4. **Enable transport encryption**
+   ```bash
+   # Edit .env and set
+   TRANSPORT_ENCRYPTION=true
+   ```
+
+5. **Done!** Access via `https://nofx.yourdomain.com`
+
+---
+
+## Initial Setup (Web Interface)
+
+After starting the system, configure through the web interface:
+
+1. **Configure AI Models** - Add your AI API keys (DeepSeek, OpenAI, etc.)
+2. **Configure Exchanges** - Set up exchange API credentials
+3. **Create Strategy** - Configure trading strategy in Strategy Studio
+4. **Create Trader** - Combine AI model + Exchange + Strategy
+5. **Start Trading** - Launch your configured traders
+
+All configuration is done through the web interface - no JSON file editing required.
+
+---

+```
+
+### AI API timeout
+- Check if API key is correct
+- Check network connection

-- 创建、启动、查询、编辑、删除 agent
-- 管理交易所配置
-- 管理策略
-- 管理大模型配置
-- 排查配置问题与运行问题
-- 回答交易相关问题，并提供可执行的建议
-
-助手的价值不在于“会聊天”，而在于：
-
-- 降低用户操作成本
-- 减少配置错误和误操作
-- 提高问题定位效率
-- 让交易过程更专业、更可靠
-
-## 核心理念
-
-本助手采用 `80% skill + 20% 动态规划` 的设计思路。
-
-这意味着：
-
-- 大多数高频、已知、可标准化的需求，应由预定义 skill 处理
-- 不应让模型对已知流程重复思考
-- 动态规划只用于少数复杂、跨领域、未知或开放性任务
-- 能确定的事情就不要交给模型自由发挥
-
-默认优先级如下：
-
-1. 优先匹配 skill
-2. 如果用户仍在当前任务中，则继续当前 skill
-3. 只有当没有合适 skill 时，才进入动态规划
-
-## 设计原则
-
-### 1. 以 Skill 为主，不以自由推理为主
-
-对于高频任务和高风险任务，必须优先使用 skill，而不是通用 agent 自行规划。
-
-尤其是以下场景：
-
-- 创建 agent
-- 启动或停止 agent
-- 新增或修改交易所配置
-- 新增或修改策略
-- 新增或修改模型配置
-- 常见报错排查
-- API 配置指导
-
-这些任务都应有稳定、明确、可重复执行的处理路径。
-
-### 2. 以用户任务为中心，不以内部对象或 API 为中心
-
-skill 的拆分应该围绕“用户想完成什么任务”，而不是“系统里有哪些对象”或“有哪些接口”。
-
-好的拆分方式：
-
-- 创建一个 agent
-- 启动或停止一个 agent
-- 排查交易所 API 连接失败
-- 指导用户配置某个模型的 API
-- 解释某条报错并给出下一步
-
-不好的拆分方式：
-
-- exchange skill
-- strategy 对象 skill
-- 通用 REST 调用 skill
-- 纯接口包装型 skill
-
-用户关注的是任务结果，不是内部实现。
-
-### 3. 多轮对话的目标是推进任务，不是维持聊天感
-
-多轮对话的本质，不是“让助手显得更像人”，而是让任务从模糊走向完成。
-
-每一轮都应围绕以下问题展开：
-
-- 当前正在处理什么任务
-- 当前任务已经确认了哪些信息
-- 还缺什么关键信息
-- 下一步最合理的推进动作是什么
-
-### 4. 只追问必要信息
-
-当任务可以继续推进时，不要提出宽泛、发散、无助于执行的问题。
-
-助手只应追问：
-
-- 当前任务必需但缺失的字段
-- 影响结果的重要选择项
-- 涉及风险、删除、替换、启动、停止等动作时的确认信息
-
-不要要求用户重复已经确认过的信息。
-
-### 5. 尽量减少不必要的思考
-
-对于已有稳定处理路径的任务，直接按既定流程执行，不进行自由规划。
-
-不要把模型能力浪费在这些事情上：
-
-- 猜测标准流程
-- 重新设计高频任务执行顺序
-- 对常见配置问题进行开放式发散分析
-- 对结构化任务做不必要的“创造性理解”
-
-### 6. 高风险动作优先保证安全
-
-任何可能造成损失、误操作、难以回滚或影响实盘的动作，都必须谨慎处理。
-
-以下动作通常需要明确确认：
-
-- 删除 agent
-- 删除交易所配置
-- 删除策略
-- 覆盖已有配置
-- 启动实盘 agent
-- 停止正在运行的 agent
-- 修改可能影响下单行为的关键参数
-
-当用户意图不够明确时，宁可先确认，不要直接执行。
-
-### 7. 回答要以可执行为目标
-
-当用户提问、排障、求指导时，回答应优先提供清晰的下一步，而不是停留在抽象概念。
-
-尽量围绕这三个问题组织回答：
-
-- 发生了什么
-- 为什么会这样
-- 现在该怎么做
-
-## 任务分类
-
-### 一、执行类任务
-
-执行类任务是指目标明确、结果清晰、可以落到具体系统动作上的任务。
-
-例如：
-
-- 创建 agent
-- 编辑 agent
-- 启动 agent
-- 停止 agent
-- 删除 agent
-- 创建交易所配置
-- 修改交易所配置
-- 删除交易所配置
-- 创建策略
-- 编辑策略
-- 激活策略
-- 复制策略
-- 删除策略
-- 创建模型配置
-- 修改模型配置
-- 删除模型配置
-
-这类任务应优先通过 skill 实现，避免自由规划。
-
-### 二、诊断类任务
-
-诊断类任务是指用户遇到了问题，需要助手帮助识别原因、缩小范围、给出修复步骤。
-
-例如：
-
-- 某条报错是什么意思
-- 为什么模型 API 配置失败
-- 为什么交易所 API 连接不上
-- 为什么 agent 启动失败
-- 为什么策略没有执行
-- 为什么余额、仓位、收益统计不对
-- 为什么某个配置在前端能保存，但运行时报错
-
-这类任务也应尽量 skill 化，形成稳定的排查路径，而不是每次从零分析。
-
-### 三、指导类任务
-
-指导类任务是指用户需要完成某项配置、接入、理解或选择，但不一定立刻触发系统动作。
-
-例如：
-
-- 某个模型的 API key 去哪里申请
-- 某个模型的 base URL 和 model name 怎么填
-- 某个交易所 API key 怎么创建
-- 某个交易所权限应该怎么勾选
-- 某种策略适合什么市场环境
-- 某些交易指标怎么理解
-
-这类任务应提供步骤化、实操型指导。
-
-### 四、动态规划类任务
-
-动态规划不是默认模式，而是兜底模式。
-
-只有在以下情况下，才允许进入动态规划：
-
-- 用户请求跨越多个 skill
-- 用户描述模糊，需要先探索再判断
-- 用户提出的是开放式交易问题
-- 用户的问题不属于已有 skill 覆盖范围
-- 需要组合查询、分析、判断和建议
-
-动态规划可以存在，但必须受控，不能覆盖主路径。
-
-## 多轮对话策略
-
-### 一、优先延续当前任务
-
-如果用户仍然在处理同一个任务，就继续当前任务，不要重新规划或重新路由。
-
-例如：
-
-- 用户：帮我创建一个新的 BTC agent
-- 助手：请提供交易所和模型配置
-- 用户：用我刚配的 DeepSeek
-
-这时应继续“创建 agent”这个任务，而不是重新理解成一个新的需求。
-
-### 二、多轮对话以任务状态推进为核心
-
-每个任务在多轮中都应该有明确状态，例如：
-
-- 已识别任务
-- 信息收集中
-- 等待用户确认
-- 执行中
-- 已完成
-- 执行失败，待修复
-- 已中断或已切换
-
-助手应始终知道当前任务在哪个阶段，而不是每轮都从头开始解释世界。
-
-### 三、只补齐缺失参数，不重复收集已有信息
-
-如果一个 skill 已经定义了所需字段，那么多轮中的追问应只围绕缺失字段展开。
-
-例如创建 agent 时，可能需要：
-
-- 名称
-- 交易所
-- 策略
-- 模型
-- 是否立即启动
-
-如果其中三个字段已经确认，就不要重新追问这三个字段。
-
-### 四、允许用户中途切换任务
-
-如果用户明显改变了目标，助手应允许当前任务中断，并切换到新任务。
-
-例如：
-
-- 当前任务：创建 agent
-- 用户突然说：为什么我的交易所 API 报 invalid signature
-
-这时应切换到诊断类任务，而不是强行把用户拉回创建流程。
-
-### 五、允许短暂插问，但尽量回到主任务
-
-如果用户在当前任务中插入一个简短问题，助手可以先简要回答，再视情况回到主任务。
-
-例如：
-
-- 用户正在创建策略
-- 中途问：逐仓和全仓有什么区别
-
-助手可以先给简洁解释，再继续原任务。
-
-### 六、对高风险动作单独确认
-
-即使任务流程已经基本完成，只要最后一步属于高风险动作，也要在执行前单独确认。
-
-例如：
-
-- 删除策略前确认
-- 启动实盘前确认
-- 覆盖已有配置前确认
-
-## 记忆策略
-
-### 一、记住对当前任务有用的信息
-
-当前会话中，应保留以下内容：
-
-- 当前活跃任务
-- 已确认的参数
-- 用户明确表达过的选择
-- 仍然缺失的关键字段
-- 当前排障上下文
-- 最近一次确认结果
-
-### 二、不把猜测当成记忆
-
-以下内容不应被高强度依赖：
-
-- 助手自行推断但用户未确认的偏好
-- 早前对话中的过时信息
-- 与当前任务无关的旧上下文
-- 仅基于模糊表达做出的假设
-
-如果有不确定性，应明确标注为“推测”或重新确认。
-
-### 三、敏感信息只在必要范围内使用
-
-对于 API key、密钥、凭证、账户等敏感信息：
-
-- 不要在回答中完整复述
-- 不要在无关任务中再次提起
-- 仅在当前任务确有需要时使用
-- 默认进行脱敏展示
-
-## Skill 设计规范
-
-每个 skill 都应服务于一个真实、完整、可交付的用户任务。
-
-一个好的 skill 应当具备以下特点：
-
-- 范围足够聚焦，执行稳定
-- 范围又不能过小，能够完成完整任务
-- 输入要求清晰
-- 流程尽量确定
-- 成功和失败条件明确
-- 容易扩展和维护
-
-每个 skill 至少应定义以下内容：
-
-- 处理的意图
-- 适用场景
-- 必填输入
-- 可选输入
-- 前置条件
-- 执行步骤
-- 缺少信息时如何追问
-- 哪些步骤需要确认
-- 成功后的输出格式
-- 常见失败情况
-- 对应的恢复建议
-
-## 工具使用原则
-
-工具只是 skill 或动态规划中的执行手段，不应成为助手行为设计的核心。
-
-助手不应表现为：
-
-- 一个通用 API 调用器
-- 一个只会函数路由的壳
-- 一个对常规任务也反复规划的自治代理
-
-默认顺序应为：
-
-1. 先判断是否有合适 skill
-2. 在 skill 内部调用所需工具
-3. 如果没有 skill，再进入受限动态规划
-4. 最后才考虑通用探索式工具调用
-
-## Skill 与 Tool 的分层原则
-
-Skill 和 tool 不是同一层概念。
-
-tool 是底层执行能力，skill 是面向用户任务的稳定流程。
-
-默认架构应为：
-
-用户请求 -> 匹配 skill -> skill 内部调用 tool -> 返回结果
-
-而不是：
-
-用户请求 -> 大模型直接在一堆底层 tool 中自由选择和规划
-
-### 一、Skill 是面向任务的
-
-skill 应围绕用户目标设计，例如：
-
-- 创建 agent
-- 启动或停止 agent
-- 配置交易所 API
-- 诊断模型配置失败
-- 解释某类报错
-
-skill 负责定义：
-
-- 要处理什么任务
-- 需要哪些输入
-- 缺信息时怎么追问
-- 执行顺序是什么
-- 哪些动作需要确认
-- 失败时怎么恢复
-
-### 二、Tool 是面向执行的
-
-tool 负责具体动作，不负责完整任务语义。
-
-例如：
-
-- 读取当前模型配置
-- 保存交易所配置
-- 查询 trader 列表
-- 启动某个 trader
-- 获取余额
-- 获取持仓
-
-tool 更像“系统能力”或“执行接口”，而不是用户直接感知的工作单元。
-
-### 三、优先把底层 tool 收敛到 skill 内部
-
-在 skill-first 架构下，不应默认把大量底层 tool 直接暴露给大模型。
-
-更合理的做法是：
-
-- 大模型优先决定使用哪个 skill
-- skill 内部自己决定需要调用哪些 tool
-- 用户不需要面对底层能力拆分
-- 模型也不需要在每次请求中重新拼装流程
-
-### 四、可以直接暴露给大模型的，应当是高层 skill 化能力
-
-如果某些能力需要以 function/tool 的形式提供给大模型，也应尽量保持高层抽象，而不是过度原子化。
-
-较好的直接暴露方式：
-
-- `manage_trader`
-- `manage_exchange_config`
-- `manage_model_config`
-- `manage_strategy`
-- `diagnose_trader_start_failure`
-
-较差的直接暴露方式：
-
-- `get_model_list_then_find_enabled_one`
-- `read_exchange_then_patch_field`
-- `generic_api_request`
-- 纯粹的 CRUD 原子碎片接口
-
-也就是说，即使最终在技术实现上仍然使用 tool calling，这些 tool 也应该尽量表现为 skill，而不是裸露的底层零件。
-
-### 五、只有在以下情况，才允许直接使用底层 tool
-
-- 当前请求没有匹配 skill
-- 请求属于探索式、一次性、低频问题
-- 需要动态组合多个能力处理未知问题
-- 当前是在做诊断型探索，而不是执行标准流程
-
-即使如此，也应优先限制范围，避免进入无边界的自由调用。
-
-### 六、设计目标
-
-引入 skill 的目的，不是让系统层次变复杂，而是让大模型少思考那些不需要思考的事情。
-
-因此分层目标应是：
-
-- 高频任务由 skill 固化
-- 低层动作沉到 skill 内部
-- 大模型少接触原子化 tool
-- 只有少数未知问题才进入动态规划
-
-## 交易场景下的行为要求
-
-交易助手必须让整体体验显得专业、谨慎、清晰。
-
-这意味着：
-
-- 操作建议要结构化
-- 配置指导要准确
-- 风险提示要明确
-- 不确定性要说清楚
-- 不应伪装成对市场有绝对把握
-
-当涉及交易建议时，应尽量区分：
-
-- 客观事实
-- 助手判断
-- 用户可执行的下一步
-
-对于行情和策略分析，应优先给出条件化建议，而不是绝对判断。
-
-例如应更倾向于：
-
-- 如果你是震荡思路，可以考虑……
-- 如果当前目标是降低回撤，优先检查……
-- 这个现象更像是配置问题，不一定是策略本身失效
-
-而不是：
-
-- 这个市场一定会涨
-- 你应该马上开多
-- 这个策略就是最优解
-
-## 默认处理流程
-
-当用户发来请求时，助手默认按以下顺序处理：
-
-1. 先判断这是不是一个已知高频任务
-2. 如果是，直接进入对应 skill
-3. 如果任务信息不完整，只追问继续执行所需的最少字段
-4. 如果属于诊断问题，先判断问题类型，再进入对应排查路径
-5. 如果属于开放式问题或跨 skill 问题，才进入动态规划
-6. 如果涉及高风险动作，在执行前单独确认
-7. 完成后给出简洁、明确、可执行的结果反馈
-
-## 总结原则
-
-本助手的核心不是“尽可能多地思考”，而是“在正确的地方思考”。
-
-应当 skill 化的事情，就不要交给模型自由发挥。
-应当标准化的流程，就不要每次重新规划。
-应当确认的风险动作，就不要直接执行。
-
-多轮对话的价值，在于持续推进任务、减少用户负担、提升交易操作质量。
-
-## 当前落地状态
-
-第一批诊断与配置类 skill 已开始沉淀，见：
-
-- `docs/agent-skills/diagnostic-skills.zh-CN.md`
-
-当前实现优先覆盖：
-
-- 模型 API 配置与诊断
-- 交易所 API 配置与诊断
-- trader 启动与运行诊断
-- 下单与仓位异常诊断
-- 策略与 prompt 生效问题诊断
-
-## 当前能力分层建议
-
-下面这部分用于指导后续 agent 重构：哪些现有能力适合继续保留给大模型，哪些应该下沉到 skill 内部，哪些应该弱化或移除。
-
-### 一、建议保留为高层 skill 的能力
-
-这些能力已经接近“用户任务”粒度，适合继续保留为高层入口。
-
-- `manage_trader`
-- `manage_exchange_config`
-- `manage_model_config`
-- `manage_strategy`
-- `execute_trade`
-- `get_positions`
-- `get_balance`
-- `get_trade_history`
-- `search_stock`
-
-原因：
-
-- 用户会直接表达这类任务
-- 这些能力已经具备较完整的业务语义
-- 它们天然适合作为 skill 或 skill-like tool
-
-后续建议：
-
-- 保持这些能力对外稳定
-- 在其上继续补充确认规则、缺参追问规则和诊断分支
-
-### 二、建议下沉到 skill 内部的能力
-
-这些能力可以继续存在，但不应作为主要交互层暴露给大模型自由组合。
-
-- 读取某个资源后再 patch 某个字段
-- 各类配置查询后再拼装参数
-- 针对单一字段的修改动作
-- 仅为执行中间步骤服务的查询动作
-- 各种“先查一下列表再让模型自己猜怎么用”的细碎能力
-
-原因：
-
-- 这类能力更像流程零件
-- 一旦直接暴露给大模型，会导致每次都重新规划
-- 会让高频任务变得不稳定且冗长
-
-原则上，这些动作应由 skill 内部封装完成，而不是让模型临场拼接。
-
-### 三、建议弱化的能力形态
-
-以下设计方向应尽量弱化：
-
-- 通用 `generic_api_request`
-- 纯 CRUD 原子接口直接暴露给大模型
-- 没有任务语义的“万能工具”
-- 需要模型自己理解完整调用顺序的碎片化接口
-
-原因：
-
-- 这类能力过于底层
-- 会把流程控制权交还给模型
-- 与“80%% skill + 20%% 动态规划”的目标相冲突
-
-### 四、建议新增的高层 skill 结构
-
-后续不建议把高频管理操作拆成大量 `skill_create_xxx / skill_update_xxx` 形式。
-
-更合理的方式是按“资源管理域”收敛为少量 management skill：
-
-- `trader_management`
-- `exchange_management`
-- `model_management`
-- `strategy_management`
-
-这些 management skill 可以在内部继续复用现有：
-
-- `manage_trader`
-- `manage_exchange_config`
-- `manage_model_config`
-- `manage_strategy`
-
-也就是说，现有高层管理工具可以作为 management skill 的执行底座，但不应继续承担全部对话策略。
-
-#### management skill 的统一协议
-
-每个 management skill 都应至少定义：
-
-- `action`
-- `target_ref`
-- `slots`
-- `needs_confirmation`
-
-推荐结构如下：
-
-```json
-{
-  "skill": "exchange_management",
-  "action": "update",
-  "target_ref": {
-    "id": "optional",
-    "name": "主账户",
-    "alias": "optional"
-  },
-  "slots": {
-    "passphrase": "xxx"
-  },
-  "needs_confirmation": false
-}
-```
-
-#### action 规则
-
-不同 management skill 的 action 应集中定义，而不是散落在 prompt 中。
-
-- `trader_management`
-  - `create`
-  - `update`
-  - `delete`
-  - `start`
-  - `stop`
-  - `query`
-- `exchange_management`
-  - `create`
-  - `update`
-  - `delete`
-  - `query`
-- `model_management`
-  - `create`
-  - `update`
-  - `delete`
-  - `query`
-- `strategy_management`
-  - `create`
-  - `update`
-  - `delete`
-  - `activate`
-  - `duplicate`
-  - `query`
-
-#### reference 规则
-
-management skill 不应要求用户总是提供精确 id，而应支持分层定位目标：
-
-1. 优先使用 `id`
-2. 其次使用 `name`
-3. 再其次使用 alias / 最近上下文引用
-4. 若命中多个对象，则要求用户明确选择
-5. 若未命中任何对象，则返回“未找到目标对象”，而不是猜测执行
-
-#### slot 规则
-
-每个 action 都应定义：
-
-- 必填 slots
-- 可选 slots
-- 自动推断规则
-- 缺失字段时的最小追问规则
-
-例如：
-
-- `exchange_management.create`
-  - 必填：`exchange_type`
-  - 常见必填：`account_name`、凭证字段
-- `exchange_management.update`
-  - 必填：`target_ref`
-  - 其余只需要用户明确要改的字段
-- `trader_management.create`
-  - 必填：`name`、`exchange`、`model`
-  - 常见可选：`strategy`、`auto_start`
-
-#### confirmation 规则
-
-management skill 内部必须按 action 级别区分风险，而不是统一处理。
-
-- `delete` 默认必须确认
-- `start` / `stop` 视场景确认
-- `create` 通常可直接执行
-- `update` 若涉及关键配置变更，可要求确认
-- `query` 不需要确认
-
-### 五、建议新增的诊断类 skill
-
-诊断类 skill 是交易助手体验差异化的关键。
-
-建议优先固定以下能力：
-
-- `model_diagnosis`
-- `exchange_diagnosis`
-- `trader_diagnosis`
-- `order_execution_diagnosis`
-- `strategy_diagnosis`
-- `balance_position_diagnosis`
-
-这些 skill 应优先基于：
-
-- 已有代码中的真实约束
-- 现有 troubleshooting 文档
-- 真实常见错误文案
-- 当前系统的实际运行逻辑
-
-### 六、建议保留给动态规划的少数场景
-
-以下场景仍然可以保留给 planner / ReAct：
-
-- 跨多个 skill 的复合任务
-- 用户目标表述模糊，需要先澄清再决定流程
-- 开放式交易问题
-- 一次性、低频、尚未固化的问题
-- 涉及诊断探索但还没有稳定 skill 的场景
-
-动态规划应始终作为兜底层，而不是主路径。
-
-### 七、最终目标分层
-
-理想结构如下：
-
-1. 用户表达需求
-2. 系统先判断是否命中高频 skill
-3. 若命中，则进入对应 skill 流程
-4. skill 内部调用现有管理类能力或查询能力
-5. 只有未命中 skill 时，才进入 planner
-
-长期目标不是“让 planner 更聪明”，而是“让 planner 更少出场”。
-
-## `agent/tools.go` 重构清单
-
-当前 `agent/tools.go` 中主要暴露了以下工具：
-
-- `get_preferences`
-- `manage_preferences`
-- `get_exchange_configs`
-- `manage_exchange_config`
-- `get_model_configs`
-- `manage_model_config`
-- `get_strategies`
-- `manage_strategy`
-- `manage_trader`
-- `search_stock`
-- `execute_trade`
-- `get_positions`
-- `get_balance`
-- `get_market_price`
-- `get_trade_history`
-
-下面给出按当前设计目标的建议分类。
-
-### 一、建议继续保留为高层入口的工具
-
-这些工具已经具备较完整的任务语义，短期内可以继续作为高层 skill-like tool 保留。
-
-- `manage_exchange_config`
-- `manage_model_config`
-- `manage_strategy`
-- `manage_trader`
-- `execute_trade`
-
-原因：
-
-- 它们都对应明确的用户任务
-- 内部已经承载了一定业务语义
-- 后续可以直接继续向 skill 演进，而不是推倒重来
-
-重构建议：
-
-- 保持接口稳定
-- 在 planner / prompt 层优先把它们当作 management skill 的执行底座使用
-- 后续逐步把对话语义前移到 `xxx_management`
-
-### 二、建议保留为“只读能力”但弱化对外存在感的工具
-
-这些工具适合继续保留，但主要作为查询型能力存在，不应成为复杂任务的主流程控制中心。
-
-- `get_exchange_configs`
-- `get_model_configs`
-- `get_strategies`
-- `get_positions`
-- `get_balance`
-- `get_market_price`
-- `get_trade_history`
-- `search_stock`
-
-原因：
-
-- 它们更适合做信息补充和状态验证
-- 对诊断问题很有价值
-- 但不应该替代 task-level skill
-
-重构建议：
-
-- 继续保留
-- 主要用于：
-  - skill 内部验证
-  - 诊断类 skill 查询当前状态
-  - 明确的只读用户请求
-- 不要鼓励模型把它们当成“拼工作流”的基础零件反复组合
-
-### 三、建议进一步收敛使用边界的工具
-
-以下工具容易把模型带回到底层操作思维，应该明确边界。
-
-- `get_preferences`
-- `manage_preferences`
-
-原因：
-
-- 长期偏好记忆是辅助能力，不是交易任务主线
-- 如果让模型频繁自由改偏好，容易污染上下文
-
-重构建议：
-
-- 仅在用户明确表达“记住/修改/删除长期偏好”时使用
-- 不要把偏好系统混进交易执行和排障主流程
-
-### 四、建议前移为 management / diagnosis skill 的现有高层工具
-
-下面这些现有高层工具虽然可用，但语义仍然过宽，建议后续逐步前移为 management / diagnosis skill。
-
-#### 1. `manage_trader`
-
-建议逐步前移为：
-
-- `trader_management`
-- `trader_diagnosis`
-
-原因：
-
-- 创建、修改、启动、停止、删除虽然动作不同，但属于同一资源管理域
-- 诊断路径和执行路径应分开
-
-#### 2. `manage_exchange_config`
-
-建议逐步前移为：
-
-- `exchange_management`
-- `exchange_diagnosis`
-
-原因：
-
-- CRUD / query 属于同一资源管理域
-- invalid signature / timestamp / IP 白名单问题需要单独诊断路径
-
-#### 3. `manage_model_config`
-
-建议逐步前移为：
-
-- `model_management`
-- `model_diagnosis`
-
-原因：
-
-- 模型对象管理应集中到一个 management skill
-- provider 配置失败和运行失败应集中到 diagnosis skill
-
-#### 4. `manage_strategy`
-
-建议逐步前移为：
-
-- `strategy_management`
-- `strategy_diagnosis`
-
-原因：
-
-- 策略模板管理和策略问题排查是两类不同任务
-- create / update / activate / duplicate / delete / query 可以统一在 management skill 内处理
-
-### 五、当前最适合直接做成硬 skill 的第一批对象
-
-如果后续开始从“prompt 约束”走向“真正 dispatcher + skill runner”，建议优先落以下几类：
-
-1. `create_trader`
-2. `trader_management`
-3. `exchange_management`
-4. `model_management`
-5. `exchange_diagnosis`
-6. `model_diagnosis`
-7. `trader_diagnosis`
-
-原因：
-
-- 这些最常见
-- 多轮价值最高
-- 失败成本高
-- 用户对稳定性的感知最强
-
-### 六、最终目标
-
-`agent/tools.go` 中的工具未来应逐步承担“skill 的执行底座”角色，而不是直接承担全部对话策略。
-
-也就是说，长期理想状态是：
-
-- 文档层：按 skill 组织
-- 对话层：先匹配 skill
-- 执行层：skill 内部复用现有 tool
-- planner 层：只兜底少数复杂情况

-# NOFXi 诊断与配置 Skills（第一批）
-
-这份文档用于沉淀交易智能助手的第一批高频诊断与配置 skill。
-
-目标不是让模型“更会想”，而是让它面对常见问题时，优先走稳定、可复用的排查路径。
-
-## 设计原则
-
-- 优先按 skill 回答，不要对高频问题重复自由规划
-- 先归类问题，再给出原因、检查项和修复建议
-- 能通过工具验证当前状态时，先查再下结论
-- 敏感信息只指导填写，不完整回显
-- 对结论不确定时，要明确标注为“更可能”或“优先怀疑”
-
-## skill_model_api_setup
-
-### 适用场景
-
-- 用户问某个大模型的 API key 去哪里申请
-- 用户问 base URL 怎么填
-- 用户问 model name 怎么填
-- 用户问 OpenAI / Claude / Gemini / DeepSeek / Qwen / Kimi / Grok / MiniMax 怎么接入
-
-### 处理策略
-
-1. 先确认用户要配置哪个 provider
-2. 告诉用户需要准备的最少字段：
-   - provider
-   - API key
-   - custom_api_url
-   - custom_model_name
-3. 如果系统已有默认地址和默认模型名，优先给推荐值
-4. 回答按步骤组织，不要泛泛解释概念
-
-### 已知实现事实
-
-- 系统内置 provider 默认运行配置，见 `agent.resolveModelRuntimeConfig(...)`
-- 常见 provider 已有默认 URL 和默认 model name
-
-## skill_model_config_diagnosis
-
-### 适用场景
-
-- 模型保存成功但 agent 仍然不可用
-- 提示 AI unavailable
-- 提示模型没启用
-- 提示 custom_api_url 不合法
-- 配置后 trader 不生效
-
-### 优先排查
-
-1. 是否存在已启用模型
-2. API key 是否为空
-3. custom_api_url 是否为合法 HTTPS 地址
-4. custom_model_name 是否为空或不匹配
-5. 当前 trader 是否绑定了这个模型
-6. 更新模型后是否已触发 trader reload
-
-### 已知实现事实
-
-- 非 HTTPS 的 `custom_api_url` 会被后端拒绝，见 `api/handler_ai_model.go`
-- 已启用模型如果缺少 API Key 或 URL，会导致 agent 无法就绪，见 `agent.ensureAIClientForStoreUser(...)`
-- 更新模型配置后，系统会尝试移除并重载相关 trader，使新配置立即生效
-
-### 输出格式
-
-- 现象
-- 更可能原因
-- 先检查什么
-- 下一步怎么修复
-
-## skill_exchange_api_setup
-
-### 适用场景
-
-- 用户要新建交易所 API
-- 用户不知道交易所需要哪些权限
-- 用户问 API key / secret / passphrase 分别填什么
-
-### 通用处理策略
-
-1. 先确认交易所类型
-2. 告知必须权限与禁止权限
-3. 告知是否需要额外字段
-4. 强调 IP 白名单与权限配置
-5. 引导用户回到系统内完成绑定
-
-### 特殊规则
-
-- OKX 除 API Key 和 Secret 外，还需要 passphrase
-- Bybit 永续/合约交易需要合约权限
-- 不建议开启提现权限
-
-### 参考文档
-
-- `docs/getting-started/okx-api.md`
-- `docs/getting-started/bybit-api.md`
-
-## skill_exchange_api_diagnosis
-
-### 适用场景
-
-- `invalid signature`
-- `timestamp` 错误
-- `IP not allowed`
-- `permission denied`
-- 交易所连接不上
-
-### 优先排查
-
-1. 系统时间是否同步
-2. API Key / Secret 是否正确
-3. 是否遗漏额外字段，如 OKX passphrase
-4. IP 白名单是否包含当前服务器
-5. 是否启用了交易或合约权限
-6. 密钥是否过期或已重建
-
-### 已知实现事实
-
-- 时间不同步是 `invalid signature` / `timestamp` 的高频根因，见 `docs/guides/TROUBLESHOOTING.zh-CN.md`
-- OKX 的 passphrase 缺失会导致签名相关问题，见 `docs/getting-started/okx-api.md`
-
-### 输出格式
-
-- 报错现象
-- 最常见根因
-- 优先检查顺序
-- 修复步骤
-
-## skill_trader_start_diagnosis
-
-### 适用场景
-
-- trader 启动不了
-- trader 启动了但没开始交易
-- 页面显示已启动但一直没有动作
-- 用户怀疑 strategy / model / exchange 绑定有问题
-
-### 优先排查
-
-1. 是否有已启用的模型配置
-2. 是否有已启用的交易所配置
-3. trader 是否绑定了 exchange_id / strategy_id / ai_model_id
-4. 交易所余额和权限是否满足下单条件
-5. AI 最近的决策到底是 wait、hold 还是下单失败
-
-### 回答原则
-
-- 要区分“没启动”“启动了但 AI 选择不交易”“尝试下单但失败”这三类
-- 不要把“没开仓”直接等同于“系统故障”
-
-## skill_order_execution_diagnosis
-
-### 适用场景
-
-- 下单失败
-- 只开空不开户 / 只开单边
-- 杠杆报错
-- position side mismatch
-
-### 优先排查
-
-1. 账户模式是否匹配，例如 Binance 是否为 Hedge Mode
-2. 是否为子账户杠杆限制
-3. 合约权限是否开启
-4. 余额、保证金、可交易 symbol 是否满足条件
-
-### 已知实现事实
-
-- Binance 在 One-way Mode 下，可能出现 `position side mismatch` 或单边行为
-- 某些子账户杠杆上限较低，超过限制会直接失败
-- 这些问题在 `docs/guides/TROUBLESHOOTING.md` 已有明确说明
-
-## skill_strategy_diagnosis
-
-### 适用场景
-
-- 用户说策略没生效
-- 用户说 prompt 预览和实际不一致
-- 用户说修改策略后 trader 行为没有变化
-
-### 优先排查
-
-1. 当前编辑的是策略模板，还是 trader 的 custom prompt
-2. 策略是否真的保存成功
-3. 是否需要重新读取当前配置做对比
-4. 用户说的“没生效”是指未保存、未绑定，还是运行结果与预期不一致
-
-### 回答原则
-
-- 先明确“对象”再排查：strategy template / trader / prompt override
-- 如果能读取当前保存值，就不要凭印象判断
-
-## 后续扩展方向
-
-下一批可以继续补：
-
-- `skill_balance_and_position_diagnosis`
-- `skill_market_data_diagnosis`
-- `skill_prompt_generation_diagnosis`
-- `skill_strategy_test_run_diagnosis`
-- `skill_exchange_specific_setup_<exchange>`

-# NOFXi Agent 当前设计说明
-
-## 目的
-
-本文描述当前 NOFXi Agent 的实际设计，而不是早期版本的理想设计。重点回答这些问题：
-
-- 用户消息从哪里进入
-- 什么请求会进入 planner
-- 当前有哪些记忆层
-- planner 如何生成与执行 plan
-- tool 现在是怎么设计的
-- 动态快照和当前引用分别解决什么问题
-- 为什么某些问题会出现“看起来有历史，但模型还是会追问”
-
-本文对应的主要实现文件：
-
-- `agent/agent.go`
-- `agent/web.go`
-- `api/agent_routes.go`
-- `agent/planner_runtime.go`
-- `agent/execution_state.go`
-- `agent/memory.go`
-- `agent/history.go`
-- `agent/tools.go`
-
-## 一句话总览
-
-当前 Agent 的运行模型可以概括为：
-
-1. 前端把消息发到 `/api/agent/chat/stream`
-2. 后端把登录用户身份放进 context
-3. Agent 除 `/clear` 和 `/status` 外，其他消息全部进入 planner
-4. planner 结合多层记忆、动态快照和 tool schema 生成 plan
-5. 执行 plan 中的 `tool / reason / ask_user / respond`
-6. 在执行过程中持续更新执行态、短期原话、长期摘要和当前对象引用
-
-## 请求入口
-
-### 前端入口
-
-前端 Agent 页面在：
-
-- `web/src/pages/AgentChatPage.tsx`
-
-当前聊天使用：
-
-- `POST /api/agent/chat/stream`
-
-请求体里会传：
-
-- `message`
-- `lang`
-- `user_key`
-
-### 后端路由入口
-
-路由注册在：
-
-- `api/agent_routes.go`
-
-这里会：
-
-1. 经过 `authMiddleware`
-2. 从登录态里取出 `user_id`
-3. 通过 `agent.WithStoreUserID(...)` 写入 request context
-
-### Agent Web Handler
-
-真正的 HTTP handler 在：
-
-- `agent/web.go`
-
-主要入口：
-
-- `HandleChat(...)`
-- `HandleChatStream(...)`
-
-再往下进入：
-
-- `HandleMessageForStoreUser(...)`
-- `HandleMessageStreamForStoreUser(...)`
-
-## 最外层分流
-
-当前外层分流已经被收口。
-
-在 `agent/agent.go` 中，除了这两个命令之外，其他输入全部交给 planner：
-
-- `/clear`
-- `/status`
-
-也就是说，现在这些都不再在外层直接处理：
-
-- setup flow
-- trade confirmation
-- direct trade regex
-- 自然语言配置流程
-- 自然语言策略创建
-
-这些都统一进入 planner。
-
-这是当前设计里一个很重要的原则：
-
-- 外层分流越少，行为边界越清晰
-- 自然语言理解尽量统一交给 planner + tool
-
-## 当前的 5 层记忆
-
-当前不是 3 层，也不是 4 层，而是 5 层：
-
-1. `chatHistory`
-2. `TaskState`
-3. `ExecutionState`
-4. `CurrentReferences`
-5. `Persistent Preferences`
-
-### 1. chatHistory
-
-定义位置：
-
-- `agent/history.go`
-
-作用：
-
-- 保存最近几轮用户 / assistant 原始消息
-- 给模型保留最近原话上下文
-- 为后续摘要成 `TaskState` 提供原始素材
-
-特点：
-
-- 只保留短期原话
-- 内存态
-- `/clear` 时清空
-
-适合存：
-
-- 最近几轮对话原文
-- 用户的最新措辞
-- 刚刚的自然语言上下文
-
-不适合存：
-
-- 长期真相
-- 当前外部系统状态
-- 当前流程精确执行位置
-
-### 2. TaskState
-
-定义位置：
-
-- `agent/memory.go`
-
-作用：
-
-- 保存跨轮次仍然有意义的高层摘要
-- 注入 planner / reasoning / final response
-
-持久化 key：
-
-- `agent_task_state_<userID>`
-
-字段：
-
-- `CurrentGoal`
-- `ActiveFlow`
-- `OpenLoops`
-- `ImportantFacts`
-- `LastDecision`
-- `UpdatedAt`
-
-适合存：
-
-- 当前高层目标
-- 跨轮次仍然成立的未闭环事项
-- 关键事实
-- 最近一次重要决策及其原因
-
-不适合存：
-
-- step 级待办
-- “下一步调用哪个 tool”
-- 动态余额、持仓、配置存在性
-- 任何可以通过 tool 重新读取的实时状态
-
-### 3. ExecutionState
-
-定义位置：
-
-- `agent/execution_state.go`
-
-作用：
-
-- 保存当前 plan 的执行态
-- 支持 `ask_user` 之后继续执行
-- 保存 plan、当前步骤、执行日志、等待状态等
-
-持久化 key：
-
-- `agent_execution_state_<userID>`
-
-当前关键字段：
-
-- `SessionID`
-- `Goal`
-- `Status`
-- `PlanID`
-- `Steps`
-- `CurrentStepID`
-- `DynamicSnapshots`
-- `ExecutionLog`
-- `SummaryNotes`
-- `Waiting`
-- `CurrentReferences`
-- `FinalAnswer`
-- `LastError`
-
-### 4. CurrentReferences
-
-定义位置：
-
-- `agent/execution_state.go`
-
-作用：
-
-- 记录当前对话里“这个 / 那个 / 刚才那个”到底指的是谁
-
-当前支持的引用对象：
-
-- `strategy`
-- `trader`
-- `model`
-- `exchange`
-
-这是为了解决一种常见问题：
-
-- 用户明明前一轮刚说过“激进策略”
-- 下一轮说“改一下这个策略”
-- 如果没有结构化引用，模型虽然有聊天历史，也容易重新追问
-
-`CurrentReferences` 不是系统状态快照，而是：
-
-- 当前对话焦点对象
-- 当前代词绑定对象
-
-### 5. Persistent Preferences
-
-对应工具：
-
-- `get_preferences`
-- `manage_preferences`
-
-作用：
-
-- 保存用户长期偏好
-
-适合存：
-
-- 默认中文回复
-- 偏好激进风格
-- 更关注 BTC / ETH
-- 不喜欢高频
-- 每天固定时间简报
-
-它和 `TaskState` 的区别是：
-
-- `TaskState` 偏向当前任务摘要
-- `Persistent Preferences` 偏向长期用户画像
-
-## DynamicSnapshots 是什么
-
-`DynamicSnapshots` 是当前真实系统状态的快照。
-
-它不是历史，也不是长期记忆，而是 planner 在规划前或执行中插入的“当前事实”。
-
-当前会进入快照的典型信息包括：
-
-- 当前模型配置列表
-- 当前交易所配置列表
-- 当前策略列表
-- 当前 trader 列表
-- 当前余额
-- 当前持仓
-- 最近交易历史
-
-作用：
-
-- 防止 planner 盲信旧结论
-- 避免“之前没配置，现在其实已经配好了却还说没有”
-- 避免“之前余额是 A，现在拿旧 observation 继续回答”
-
-一句话：
-
-- `DynamicSnapshots` = 当前世界里真实有什么
-
-## CurrentReferences 和 DynamicSnapshots 的区别
-
-这两个容易混淆，但职责完全不同。
-
-`DynamicSnapshots`：
-
-- 当前系统状态快照
-- 是候选集合 / 当前事实
-- 例如当前有两个策略：`激进`、`新策略`
-
-`CurrentReferences`：
-
-- 当前对话焦点对象
-- 是“这个”到底指谁
-- 例如用户现在说的“这个策略”就是 `激进`
-
-可以这样理解：
-
-- `DynamicSnapshots` 是地图
-- `CurrentReferences` 是你手指现在指着地图上的哪个点
-
-## Planner 的输入
-
-planner 主逻辑在：
-
-- `agent/planner_runtime.go`
-
-生成计划时，当前会把这些东西一起送给模型：
-
-- 当前用户请求
-- tool schema
-- `Persistent Preferences`
-- `TaskState`
-- `ExecutionState`
-- `Resume context`
-- `Structured waiting state`
-- `Observation context`
-
-其中 observation context 不是旧版单数组，而是分层后的：
-
-- `dynamic_snapshots`
-- `execution_log`
-- `summary_notes`
-
-## Plan 的结构
-
-当前 planner 只允许这 4 类 step：
-
-- `tool`
-- `reason`
-- `ask_user`
-- `respond`
-
-这意味着现在的 Agent 不是一个“自由发挥的回复器”，而是：
-
-- 先规划
-- 再执行步骤
-- 必要时重规划
-
-## 步骤执行流程
-
-`executePlan(...)` 的核心逻辑是：
-
-1. 找下一个 pending step
-2. 标记 step 为 running
-3. 执行对应类型
-4. 写回 `ExecutionState`
-5. 必要时触发 replanning
-
-不同 step 类型行为如下：
-
-### tool
-
-- 调内部 tool
-- 把结果写入 `ExecutionLog`
-- 根据结果更新 `CurrentReferences`
-- 必要时触发 replanner
-
-### reason
-
-- 发起一次短 reasoning 调用
-- 生成一段简短中间推理
-- 写入 `ExecutionLog`
-
-### ask_user
-
-- 进入 `waiting_user`
-- 保存 `WaitingState`
-- 把问题直接回给用户
-
-### respond
-
-- 生成最终回答
-- 标记当前执行完成
-
-## WaitingState 是什么
-
-`WaitingState` 用来解决：
-
-- 用户回复 `是`
-- 用户回复 `继续`
-- 用户回复 `那个就行`
-
-这类短回复如果没有结构化等待状态，很容易丢上下文。
-
-当前字段包括：
-
-- `Question`
-- `Intent`
-- `PendingFields`
-- `ConfirmationTarget`
-- `CreatedAt`
-
-它的作用是：
-
-- 告诉 planner 上一轮到底在等什么
-- 让这轮短回复更容易被理解成“对上一问的回答”
-
-## CurrentReferences 如何更新
-
-当前是双路径更新：
-
-### 1. 用户消息命中对象名时更新
-
-如果用户说：
-
-- `修改激进策略`
-- `停止 lky`
-- `用 DeepSeek`
-
-系统会去当前用户的策略 / trader / model / exchange 列表里尝试匹配名称或 ID。
-
-匹配成功后，更新 `CurrentReferences`。
-
-### 2. tool 成功返回对象时更新
-
-比如：
-
-- `manage_strategy(create/update/activate)`
-- `manage_trader(create/update)`
-- `manage_model_config(update)`
-- `manage_exchange_config(update)`
-
-只要 tool 返回了具体对象，系统就会把对应 ID / name 写回当前引用。
-
-## Tool 设计
-
-当前 tool 是“资源型 tool”设计，不是“页面动作型 tool”。
-
-### 当前主要工具
-
-配置资源：
-
-- `get_exchange_configs`
-- `manage_exchange_config`
-- `get_model_configs`
-- `manage_model_config`
-
-策略资源：
-
-- `get_strategies`
-- `manage_strategy`
-
-trader 资源：
-
-- `manage_trader`
-
-交易 / 查询资源：
-
-- `search_stock`
-- `execute_trade`
-- `get_positions`
-- `get_balance`
-- `get_market_price`
-- `get_trade_history`
-
-### 为什么这么设计
-
-优点：
-
-- tool schema 稳定
-- 行为边界清晰
-- planner 更容易学会
-- 资源增删改查统一
-
-当前 `manage_strategy` 支持：
-
-- `list`
-- `get_default_config`
-- `create`
-- `update`
-- `delete`
-- `activate`
-- `duplicate`
-
-当前 `manage_trader` 支持：
-
-- `list`
-- `create`
-- `update`
-- `delete`
-- `start`
-- `stop`
-
-## 为什么“创建策略”不该默认依赖交易所和模型
-
-当前设计里，策略模板应该是独立资源：
-
-- `strategy`
-
-而运行态对象是：
-
-- `trader`
-
-更合理的边界是：
-
-- 创建策略模板：用 `manage_strategy`
-- 把策略跑起来：用 `manage_trader`
-
-也就是说：
-
-- 策略不默认依赖交易所和模型
-- 只有当用户要求“运行 / 部署 / 创建 trader”时，才需要进一步关联 exchange / model / trader
-
-## 当前一个完整例子
-
-用户输入：
-
-`帮我创建一个新的激进策略模板，名字就叫激进。创建完后，再把这个策略绑定到 trader lky。`
-
-当前大致流程：
-
-1. 前端请求 `/api/agent/chat/stream`
-2. 后端注入 `store_user_id`
-3. Agent 进入 planner
-4. planner 刷新动态快照：
-   - 当前策略
-   - 当前 trader
-5. 生成 plan，例如：
-   - `get_strategies`
-   - `manage_strategy(create)`
-   - `manage_trader(update)`
-   - `respond`
-6. 执行 `manage_strategy(create)` 后：
-   - 写入 `ExecutionLog`
-   - 更新 `CurrentReferences.strategy`
-7. 执行 `manage_trader(update)` 时：
-   - 直接使用刚创建策略的 ID
-8. 输出最终回复
-
-如果此后用户继续说：
-
-`把这个策略的 prompt 改激进一点`
-
-系统会优先从 `CurrentReferences.strategy` 理解“这个策略”。
-
-## 为什么看起来“有历史”，模型还是会追问
-
-因为“有聊天历史”不等于“有结构化对象绑定”。
-
-如果没有 `CurrentReferences`：
-
-- 模型只能依赖原话文本推断“这个策略”是谁
-- 一旦中间插入多条消息，或者有多个候选策略
-- 就容易重新追问
-
-所以当前设计里，`CurrentReferences` 是补齐这一块的关键。
-
-## 当前已知限制
-
-### 1. 外层虽然已经大幅收口，但仍然不是纯 graph runtime
-
-现在比之前更统一，但整体仍然是：
-
-- Agent 主入口
-- Planner
-- Tool 执行
-
-而不是完整 node-graph 引擎。
-
-### 2. ExecutionState 仍然是按 userID 单槽位
-
-这意味着：
-
-- 同一用户的多个并行任务仍然可能相互影响
-
-更彻底的方向应该是：
-
-- 按 thread / session 多实例存储
-
-### 3. CurrentReferences 目前还是轻量实现
-
-当前只覆盖：
-
-- strategy
-- trader
-- model
-- exchange
-
-后面如果要更强，需要考虑：
-
-- 多候选冲突消解
-- 昵称映射
-- 跨更长会话的稳定实体绑定
-
-## 当前设计的核心思想
-
-一句话总结：
-
-- `chatHistory` 记原话
-- `Persistent Preferences` 记长期偏好
-- `TaskState` 记高层摘要
-- `ExecutionState` 记当前流程
-- `DynamicSnapshots` 记当前事实
-- `CurrentReferences` 记当前指代对象
-- `planner` 决定步骤
-- `tools` 执行落地动作
-
-这就是当前 NOFXi Agent 的实际运行设计。

-# NOFXi Agent Memory And Planning Design
-
-## Purpose
-
-This document explains how the current NOFXi agent handles:
-
-- short-term conversation memory
-- durable task memory
-- durable execution / planning state
-- planner execution and replanning
-- state reset and resume behavior
-
-The implementation described here is primarily in:
-
-- `agent/history.go`
-- `agent/memory.go`
-- `agent/execution_state.go`
-- `agent/planner_runtime.go`
-- `agent/agent.go`
-
-## High-Level Model
-
-The current agent uses three different layers of state:
-
-1. `chatHistory`
-Recent in-memory user/assistant turns for the live conversation.
-
-2. `TaskState`
-Durable summarized context that should survive beyond recent turns.
-
-3. `ExecutionState`
-Durable workflow state for the currently running or recently blocked plan.
-
-These three layers serve different purposes and should not be treated as the same thing.
-
-## State Layers
-
-### 1. `chatHistory`
-
-Defined in `agent/history.go`.
-
-Role:
-
-- stores recent `user` / `assistant` messages in memory
-- keyed by `userID`
-- used as short-term conversational context
-- acts as the source material for later compression into `TaskState`
-
-Characteristics:
-
-- in-memory only
-- capped by `maxTurns`
-- cleared by `/clear`
-- not suitable as durable truth
-
-Typical contents:
-
-- the last few user questions
-- the last few assistant replies
-- temporary conversational wording
-
-### 2. `TaskState`
-
-Defined in `agent/memory.go`.
-
-Role:
-
-- stores durable, structured, non-derivable context
-- persisted through `system_config`
-- injected into planning and reasoning prompts
-
-Storage key:
-
-- `agent_task_state_<userID>`
-
-Fields:
-
-- `CurrentGoal`
-- `ActiveFlow`
-- `OpenLoops`
-- `ImportantFacts`
-- `LastDecision`
-- `UpdatedAt`
-
-Intended contents:
-
-- user goal that still matters across turns
-- high-level unresolved issues that still matter across turns
-- facts that tools cannot cheaply re-fetch
-- latest important decision summary
-
-Explicitly not intended for:
-
-- step-level pending items such as "wait for API key"
-- execution actions such as "call get_exchange_configs"
-- live balances
-- current positions
-- current market prices
-- mutable configuration availability
-
-Those should be checked from tools at planning time instead of being trusted from old summaries.
-
-### 3. `ExecutionState`
-
-Defined in `agent/execution_state.go`.
-
-Role:
-
-- stores the current execution workflow
-- allows the agent to resume after `ask_user`
-- persists plan steps, observations, and completion status
-
-Storage key:
-
-- `agent_execution_state_<userID>`
-
-Fields:
-
-- `SessionID`
-- `UserID`
-- `Goal`
-- `Status`
-- `PlanID`
-- `Steps`
-- `CurrentStepID`
-- `Observations`
-- `FinalAnswer`
-- `LastError`
-- `UpdatedAt`
-
-This is the planner's working state, not a general memory store.
-
-## Data Flow
-
-### Request Entry
-
-Entry points:
-
-- `HandleMessage(...)`
-- `HandleMessageStream(...)`
-
-Flow:
-
-1. user message enters `agent`
-2. slash commands and explicit direct branches are handled first
-3. all other requests go into planner flow via `thinkAndAct(...)` / `thinkAndActStream(...)`
-
-### Planner Flow
-
-The planner pipeline in `agent/planner_runtime.go` is:
-
-1. append user message into `chatHistory`
-2. emit `planning` SSE event
-3. load `ExecutionState`
-4. optionally reset stale `ExecutionState`
-5. optionally refresh dynamic configuration snapshots
-6. create a fresh execution plan with the LLM
-7. execute steps one by one
-8. persist `ExecutionState` after important transitions
-9. append assistant answer into `chatHistory`
-10. maybe compress old conversation into `TaskState`
-
-## Short-Term vs Durable Memory
-
-### What lives in `chatHistory`
-
-Good fits:
-
-- raw recent messages
-- conversational wording
-- latest assistant phrasing
-
-Bad fits:
-
-- long-lived truths
-- current external system state
-
-### What lives in `TaskState`
-
-Good fits:
-
-- durable goal
-- high-level unfinished work that remains relevant across turns
-- important facts the user stated
-- previous decisions and why they were made
-
-Bad fits:
-
-- pending steps inside the current plan
-- execution-level reminders such as "wait for a field" or "call a tool"
-- old conclusions about whether tools exist
-- old conclusions about whether model/exchange config is present
-- live operational state that can change outside the chat
-
-### What lives in `ExecutionState`
-
-Good fits:
-
-- current plan steps
-- observations from tool calls
-- blocked-on-user-input status
-- exact current workflow state
-- step-level pending work and block reasons
-
-Bad fits:
-
-- evergreen user profile
-- long-term semantic memory
-
-## Planning Logic
-
-### Plan Creation
-
-`createExecutionPlan(...)` sends the following into the planner model:
-
-- available tool definitions
-- persistent preferences
-- `TaskState` context
-- `ExecutionState` JSON
-- current user request
-
-The planner must return JSON only with step types:
-
-- `tool`
-- `reason`
-- `ask_user`
-- `respond`
-
-### Step Execution
-
-`executePlan(...)` executes the plan loop:
-
-- `tool`
-  call tool and append observation
-- `reason`
-  run reasoning sub-call and append observation
-- `ask_user`
-  save `waiting_user` state and return question
-- `respond`
-  generate final answer and mark completed
-
-After each completed step, `replanAfterStep(...)` may:
-
-- continue
-- replace remaining steps
-- ask user
-- finish
-
-## Resume Behavior
-
-When `ExecutionState.Status == waiting_user`, the next user turn is treated as a reply to the pending question.
-
-Current safeguards:
-
-- latest asked question is extracted from the stored plan
-- the user reply is appended as a `user_reply` observation
-- planner prompt receives explicit `Resume context`
-
-This prevents short replies like `是` from being misread as unrelated fresh intents as often as before.
-
-## Dynamic State Refresh
-
-Configuration and trader management requests are dynamic by nature. Their truth can change outside the current chat, for example:
-
-- user configures exchange in the UI
-- user adds model in another tab
-- user creates trader elsewhere
-
-Because of that, configuration/trader requests should not trust stale model conclusions.
-
-Current protection in `planner_runtime.go`:
-
-- detects config / trader intent with `isConfigOrTraderIntent(...)`
-- clears `TaskState` context from the planner prompt for these requests
-- refreshes `ExecutionState.Observations` with fresh snapshots from:
-  - `toolGetModelConfigs(...)`
-  - `toolGetExchangeConfigs(...)`
-  - `toolListTraders(...)`
-
-This makes the planner rely more on current system state and less on older narrative memory.
-
-## Reset Strategy
-
-The system currently resets or weakens stale execution state when:
-
-- user says retry-like phrases such as `再试`, `继续`, `try again`, `continue`
-- request is config / trader related and old execution state is failed / completed / waiting
-
-Reset scope:
-
-- `ExecutionState` may be cleared
-- `TaskState` is not globally deleted, but it is intentionally ignored for config/trader planning
-
-Manual reset:
-
-- `/clear`
-
-This clears:
-
-- short-term chat history
-- task state
-- execution state
-
-## Compression Design
-
-`maybeCompressHistory(...)` moves older short-term chat content into `TaskState` when:
-
-- recent message count exceeds the configured window
-- estimated token count exceeds the threshold
-
-Compression strategy:
-
-1. keep recent conversation in `chatHistory`
-2. summarize older turns into structured `TaskState`
-3. persist new `TaskState`
-4. replace `chatHistory` with recent slice
-
-Important design rule:
-
-- `TaskState` should keep durable context only
-- it should not become a stale copy of mutable operational state

-    running --> failed: step error
-    failed --> planning: retry / continue / config-trader reset
-    completed --> planning: new relevant request or retry flow
-```
-
-## Known Design Tradeoffs
-
-### Strengths
-
-- separates short-term chat from durable task summary
-- allows blocked flows to resume
-- supports replanning after every meaningful step
-- can recover from stale assumptions better for dynamic config/trader requests
-
-### Weaknesses
-
-- `TaskState` is still summary-driven, so summarization quality matters
-- planner still depends on model compliance for some transitions
-- `ExecutionState` is single-track per user, not multiple concurrent workflows
-- config/trader intent detection is heuristic and keyword-based
-
-## Practical Guidance
-
-### When to trust `TaskState`
-
-Trust it for:
-
-- user intent continuity
-- open loops
-- durable facts
-
-Do not trust it for:
-
-- whether current exchange/model/trader config exists now
-- whether a specific operational action is currently possible
-
-### When to trust `ExecutionState`
-
-Trust it for:
-
-- current plan continuity
-- exact blocked step
-- latest observation chain
-
-Do not trust it blindly when:
-
-- user has changed configuration outside the chat
-- the system capabilities changed after deployment
-
-### When to fetch live state again
-
-Always prefer fresh tool snapshots before answering about:
-
-- existing model configs
-- existing exchange configs
-- existing traders
-- whether trader creation can proceed
-
-## Suggested Future Improvements
-
-- add workflow versioning so capability changes invalidate stale `ExecutionState`
-- separate `waiting_user_confirmation` from generic `waiting_user`
-- introduce code-level handling for short confirmations such as `是`, `好`, `继续`
-- move dynamic state refresh from heuristic to explicit planner preflight stage
-- support multiple concurrent execution sessions per user if needed

-# NOFXi Agent 记忆与规划设计
-
-## 目的
-
-本文说明当前 NOFXi agent 是如何处理以下能力的：
-
-- 短期对话记忆
-- 持久化任务记忆
-- 持久化执行态 / 规划态
-- planner 的执行与重规划
-- 状态重置与恢复
-
-本文主要对应以下实现文件：
-
-- `agent/history.go`
-- `agent/memory.go`
-- `agent/execution_state.go`
-- `agent/planner_runtime.go`
-- `agent/agent.go`
-
-## 总体模型
-
-当前 agent 使用三层不同的状态：
-
-1. `chatHistory`
-用于保存当前会话最近几轮的原始用户/助手对话，驻留内存。
-
-2. `TaskState`
-用于保存跨轮次仍然有价值的结构化摘要，持久化存储。
-
-3. `ExecutionState`
-用于保存当前规划流程的执行态，支持流程中断后的继续执行。
-
-这三层职责不同，不能混为一谈。
-
-## 三层状态
-
-### 1. `chatHistory`
-
-定义位置：`agent/history.go`
-
-作用：
-
-- 按 `userID` 保存最近的 `user` / `assistant` 消息
-- 作为短期对话上下文
-- 作为后续压缩进 `TaskState` 的原始素材
-
-特性：
-
-- 仅在内存中存在
-- 有 `maxTurns` 上限
-- `/clear` 时会清空
-- 不适合作为长期真相来源
-
-典型内容：
-
-- 最近几轮用户问题
-- 最近几轮助手回答
-- 临时措辞与上下文表达
-
-### 2. `TaskState`
-
-定义位置：`agent/memory.go`
-
-作用：
-
-- 保存持久化、结构化、不可轻易从工具重新推导出的上下文
-- 通过 `system_config` 持久化
-- 注入到 planner / reasoning prompt 中
-
-存储 key：
-
-- `agent_task_state_<userID>`
-
-字段：
-
-- `CurrentGoal`
-- `ActiveFlow`
-- `OpenLoops`
-- `ImportantFacts`
-- `LastDecision`
-- `UpdatedAt`
-
-适合存放：
-
-- 当前仍有效的用户目标
-- 跨轮次仍然成立的高层未闭环问题
-- 无法简单通过工具重新读取的重要事实
-- 最近一次关键决策及原因
-
-不适合存放：
-
-- “等用户提供 API Key” 这类 step 级待办
-- “调用 get_exchange_configs” 这类执行动作
-- 实时余额
-- 当前持仓
-- 当前行情价格
-- 是否存在某个配置这类会变化的状态
-
-这些动态信息应该在规划阶段通过工具重新检查，而不是相信旧摘要。
-
-### 3. `ExecutionState`
-
-定义位置：`agent/execution_state.go`
-
-作用：
-
-- 保存当前执行中的工作流状态
-- 支持 `ask_user` 之后恢复执行
-- 持久化保存计划步骤、观察结果和最终状态
-
-存储 key：
-
-- `agent_execution_state_<userID>`
-
-字段：
-
-- `SessionID`
-- `UserID`
-- `Goal`
-- `Status`
-- `PlanID`
-- `Steps`
-- `CurrentStepID`
-- `Observations`
-- `FinalAnswer`
-- `LastError`
-- `UpdatedAt`
-
-它是 planner 的“工作态”，不是通用记忆仓库。
-
-## 数据流
-
-### 请求入口
-
-入口函数：
-
-- `HandleMessage(...)`
-- `HandleMessageStream(...)`
-
-流程：
-
-1. 用户消息进入 `agent`
-2. 优先处理 slash command 和显式直达分支
-3. 其余请求进入 planner 流程：`thinkAndAct(...)` / `thinkAndActStream(...)`
-
-### Planner 主流程
-
-`agent/planner_runtime.go` 中的 planner 管线如下：
-
-1. 把用户消息加入 `chatHistory`
-2. 发出 `planning` SSE 事件
-3. 加载 `ExecutionState`
-4. 视情况重置过期的 `ExecutionState`
-5. 视情况刷新动态配置快照
-6. 调用 LLM 生成新的执行计划
-7. 按步骤执行计划
-8. 在关键状态变化后持久化 `ExecutionState`
-9. 把助手回答加入 `chatHistory`
-10. 视情况把旧对话压缩进 `TaskState`
-
-## 短期记忆 vs 持久记忆
-
-### `chatHistory` 里应该放什么
-
-适合：
-
-- 最近原始消息
-- 对话措辞
-- 最近一轮助手的表达方式
-
-不适合：
-
-- 长期真相
-- 外部系统当前状态
-
-### `TaskState` 里应该放什么
-
-适合：
-
-- 持续目标
-- 跨轮次仍有意义的高层未闭环事项
-- 用户明确讲过的重要事实
-- 历史关键决策和原因
-
-不适合：
-
-- 当前 plan 中尚未执行的步骤
-- “等待某个字段”“调用某个 tool” 这类执行级待办
-- “系统有没有这个工具” 这种过时结论
-- “当前有没有模型/交易所配置” 这种可变化状态
-- 可以通过工具重新查询到的动态状态
-
-### `ExecutionState` 里应该放什么
-
-适合：
-
-- 当前计划步骤
-- 工具调用观察结果
-- 当前是否卡在等用户补充信息
-- 当前工作流的精确执行位置
-- step 级待办和阻塞原因
-
-不适合：
-
-- 长期用户画像
-- 通用长期语义记忆
-
-## 规划逻辑
-
-### 计划生成
-
-`createExecutionPlan(...)` 会把以下信息送给 planner 模型：
-
-- 当前可用 tool 定义
-- 持久化用户偏好
-- `TaskState` 上下文
-- `ExecutionState` JSON
-- 当前用户请求
-
-planner 必须返回 JSON，且步骤类型只能是：
-
-- `tool`
-- `reason`
-- `ask_user`
-- `respond`
-
-### 步骤执行
-
-`executePlan(...)` 的执行循环如下：
-
-- `tool`
-  调用工具并写入 observation
-- `reason`
-  发起 reasoning 子调用并写入 observation
-- `ask_user`
-  保存 `waiting_user` 状态并把问题返回给用户
-- `respond`
-  生成最终回答并标记完成
-
-每个步骤结束后，`replanAfterStep(...)` 还可以决定：
-
-- continue
-- replace_remaining
-- ask_user
-- finish
-
-## 恢复执行
-
-当 `ExecutionState.Status == waiting_user` 时，下一条用户消息会被视为对上一轮追问的回复。
-
-当前保护机制：
-
-- 从已有 plan 中提取最近一次追问内容
-- 将用户回复作为 `user_reply` observation 追加
-- 在 planner prompt 中注入显式的 `Resume context`
-
-这样可以减少用户只回复 `是` 这类短消息时，被错误理解成全新意图的情况。
-
-## 动态状态刷新
-
-配置类与 trader 管理类请求本质上是动态请求，它们的真相可能在聊天之外发生变化，例如：
-
-- 用户在 Web UI 中配置了交易所
-- 用户在另一个页面新增了模型
-- 用户在别处创建了 trader
-
-因此，这类请求不能依赖旧的模型结论。
-
-当前在 `planner_runtime.go` 中的保护措施：
-
-- 通过 `isConfigOrTraderIntent(...)` 检测配置 / trader 意图
-- 这类请求在 planner prompt 中不再注入旧 `TaskState`
-- 同时刷新 `ExecutionState.Observations` 中的实时快照：
-  - `toolGetModelConfigs(...)`
-  - `toolGetExchangeConfigs(...)`
-  - `toolListTraders(...)`
-
-这样 planner 会更多依赖当前系统状态，而不是依赖旧记忆中的描述。
-
-## 重置策略
-
-当前系统在以下场景会重置或弱化旧执行态：
-
-- 用户说了类似 `再试`、`继续`、`try again`、`continue`
-- 当前请求是配置 / trader 相关，并且旧 `ExecutionState` 已经失败 / 完成 / 正在等待用户
-
-重置范围：
-
-- `ExecutionState` 可能会被清空
-- `TaskState` 不会整体删除，但在配置 / trader 请求中会被主动忽略
-
-手动清理：
-
-- `/clear`
-
-这条命令会清掉：
-
-- 短期 chat history
-- task state
-- execution state
-
-## 压缩设计
-
-`maybeCompressHistory(...)` 会在以下条件满足时把旧的短期对话压缩进 `TaskState`：
-
-- 最近消息数超过窗口
-- 估算 token 数超过阈值
-
-压缩流程：
-
-1. 保留最近若干轮对话在 `chatHistory`
-2. 把更早的内容总结成结构化 `TaskState`
-3. 持久化新的 `TaskState`
-4. 用最近消息切片替换 `chatHistory`
-
-重要设计原则：
-
-- `TaskState` 只保留长期有效上下文
-- 不能把它变成动态运营状态的陈旧副本

-
-## 当前设计的取舍
-
-### 优点
-
-- 将短期对话与长期摘要分离
-- 支持在 `ask_user` 之后恢复执行
-- 每个关键步骤后都支持重规划
-- 对配置 / 创建 trader 这类动态请求，已经能更好抵抗旧结论污染
-
-### 缺点
-
-- `TaskState` 的质量仍然依赖总结效果
-- 某些恢复逻辑仍依赖模型是否听话
-- 每个用户当前只有一条 `ExecutionState`，不支持多个并发工作流
-- 配置 / trader 意图识别目前仍是关键词启发式
-
-## 实践建议
-
-### 什么时候该相信 `TaskState`
-
-应该相信它用于：
-
-- 延续用户目标
-- 跟踪未完成事项
-- 保留长期有效事实
-
-不应该相信它用于：
-
-- 当前是否存在模型 / 交易所 / trader 配置
-- 当前是否能够执行某个操作
-
-### 什么时候该相信 `ExecutionState`
-
-应该相信它用于：
-
-- 当前工作流是否仍然连续
-- 当前阻塞在哪一步
-- 最近的 observation 链条
-
-不应该盲信它用于：
-
-- 用户在聊天外已经修改过配置的场景
-- 系统能力或工具集发生变化后的旧结论
-
-### 什么时候必须重新获取实时状态
-
-以下场景应该优先重新通过工具获取：
-
-- 当前模型配置
-- 当前交易所配置
-- 当前 trader 列表
-- 当前是否满足 trader 创建条件
-
-## 后续建议
-
-- 为 `ExecutionState` 增加版本号或能力签名，能力变化时自动失效
-- 将 `waiting_user_confirmation` 与通用 `waiting_user` 分开
-- 对 `是`、`好`、`继续` 这类短确认增加代码级识别
-- 将动态快照刷新从启发式升级为显式 planner 预检查阶段
-- 如果后续需要，支持一个用户多条并发执行会话

+
+## 9. Account & Position Management
+
+**Core File:** `backtest/account.go`
+
+### 9.1 Position Structure
+
+```go
+type position struct {
+    Symbol           string
+    Side             string     // "long" or "short"
+    Quantity         float64
+    EntryPrice       float64
+    Leverage         int
+    Margin           float64    // Margin
+    Notional         float64    // Notional value
+    LiquidationPrice float64    // Liquidation price
+    OpenTime         int64
+}
+```
+
+### 9.2 Open Position Logic
+
+```go
+// backtest/account.go:61-104
+func (a *BacktestAccount) Open(symbol, side string, qty, price float64, leverage int) {
+    // 1. Apply slippage
+    // 2. Calculate notional value (qty × price)
+    // 3. Calculate margin (notional / leverage)
+    // 4. Deduct margin + fees
+    // 5. Create/add to position
+    // 6. Calculate liquidation price
+}
+```
+
+### 9.3 Close Position Logic
+
+```go
+// backtest/account.go:106-140
+func (a *BacktestAccount) Close(symbol, side string, qty, price float64) {
+    // 1. Verify position exists
+    // 2. Apply slippage (reverse direction)
+    // 3. Calculate realized PnL
+    //    long:  (exit - entry) × qty
+    //    short: (entry - exit) × qty
+    // 4. Return margin + PnL - fees
+    // 5. Update/delete position
+}
+```
+
+### 9.4 Liquidation Price Calculation
+
+```go
+// backtest/account.go:177-186
+func computeLiquidation(entry float64, leverage int, side string) float64 {
+    if side == "long" {
+        return entry * (1 - 1.0/float64(leverage))  // Long: liquidate on drop
+    }
+    return entry * (1 + 1.0/float64(leverage))      // Short: liquidate on rise
+}
+```

+func (r *Runner) maybeCheckpoint() {
+    // Save every N bars
+    // Or save every N seconds
+}
+```
+
+### 10.3 Resume Flow
+
+```go
+func (r *Runner) RestoreFromCheckpoint() {
+    // 1. Load checkpoint
+    // 2. Restore account state
+    // 3. Restore bar index (continue from next bar)
+    // 4. Restore equity curve, trade records

+### 5.2 Multi-Coin Consensus Determination
+
+**Location:** `debate/engine.go:determineMultiCoinConsensus()` (Lines 752-924)
+
+**Algorithm:**
+
+```
+1. Collect all coin decisions from all votes
+2. Group by: symbol → action → aggregated data
+
+3. For each vote decision:
+   weight = confidence / 100.0
+   Accumulate:
+   ┌─────────────────────────────────────────────────────────┐
+   │ score += weight                                         │

+   │ total_leverage += leverage                              │
+   │ total_position_pct += position_pct                      │
+   │ total_stop_loss += stop_loss                            │

+   └─────────────────────────────────────────────────────────┘
+
+4. For each symbol:
+   Find winning action (max score)
+   Calculate averages:
+   ┌─────────────────────────────────────────────────────────┐
+   │ avg_confidence = total_confidence / count               │
+   │ avg_leverage = clamp(total_leverage / count, 1, 20)     │

+   │ avg_stop_loss = default 3% if not set                   │
+   │ avg_take_profit = default 6% if not set                 │
+   └─────────────────────────────────────────────────────────┘
+
+5. Return array of consensus decisions
+```
+
+### 5.3 Consensus Example
+
+**Input Votes:**
+```
+AI1 (Bull):     BTC open_long  (conf=80, lev=10, pos=0.3)
+AI2 (Bear):     BTC open_short (conf=60, lev=5, pos=0.2)
+AI3 (Analyst):  BTC open_long  (conf=70, lev=8, pos=0.25)
+```
+
+**Calculation:**
+```
+open_long:
+  score = 0.80 + 0.70 = 1.50
+  avg_conf = (80 + 70) / 2 = 75
+  avg_lev = (10 + 8) / 2 = 9
+  avg_pos = (0.3 + 0.25) / 2 = 0.275
+
+open_short:
+  score = 0.60
+  avg_conf = 60
+  avg_lev = 5
+  avg_pos = 0.2
+
+Winner: open_long (score 1.50 > 0.60)
+```
+
+**Output:**
+```json
+{
+  "symbol": "BTCUSDT",
+  "action": "open_long",
+  "confidence": 75,
+  "leverage": 9,

+
+## 11. Integration Points
+
+### 11.1 Strategy System
+
+Debate sessions depend on saved strategies for:
+- **Coin source configuration:** static/pool/OI top
+- **Market data indicators:** K-lines, timeframes, technical indicators
+- **Risk control parameters:** leverage limits, position sizing
+- **Custom prompts:** role definition, trading rules
+
+### 11.2 AI Model System
+
+Each participant requires:
+- AI model configuration (provider, API key, custom URL)
+- Supported providers: deepseek, qwen, openai, claude, gemini, grok, kimi
+- Client initialization with timeout handling (60s per call)
+
+### 11.3 Trader System
+
+For auto-execution:
+- Requires active trader with running status
+- Trader must have valid exchange connection
+- Executor interface: `ExecuteDecision()`, `GetBalance()`
+
+### 11.4 Market Data
+
+Market context building uses:
+- Market data service (K-lines, OHLCV)
+- Quantitative data (capital flow, position changes)
+- OI ranking data (market-wide position changes)
+
+---
+
+## 12. Error Handling
+
+### 12.1 Cleanup on Startup
+
+**Location:** `debate/engine.go:cleanupStaleDebates()` (Lines 58-71)
+
+```go
+// On server restart, cancel all running/voting debates
+func cleanupStaleDebates() {
+    sessions := debateStore.ListAllSessions()
+    for _, session := range sessions {
+        if session.Status == running || session.Status == voting {
+            debateStore.UpdateSessionStatus(session.ID, cancelled)
+        }
+    }
+}
+```
+
+### 12.2 AI Call Timeout
+
+```go
+// 60 seconds per participant response
+select {
+case res := <-resultCh:
+    response = res.response
+case <-time.After(60 * time.Second):
+    return nil, fmt.Errorf("AI call timeout")
+}
+```
+
+### 12.3 Symbol Validation
+
+```go
+// Force all decisions to use session symbol if specified
+if session.Symbol != "" {
+    for _, d := range decisions {
+        if d.Symbol == "" || d.Symbol != session.Symbol {
+            logger.Warnf("Fixing invalid symbol '%s' -> '%s'", d.Symbol, session.Symbol)
+            d.Symbol = session.Symbol
+        }
+    }
+}
+```
+
+### 12.4 Panic Recovery
+
+```go
+defer func() {
+    if r := recover(); r != nil {
+        logger.Errorf("Debate panic: %v", r)
+        debateStore.UpdateSessionStatus(sessionID, cancelled)
+        if OnError != nil {
+            OnError(sessionID, fmt.Errorf("panic: %v", r))
+        }
+    }
+}()
+```
+
+---
+
+## Summary
+
+The Debate Arena module provides a sophisticated multi-AI collaborative decision system with:
+
+- **Multi-Personality Debate:** 5 distinct AI personalities (Bull, Bear, Analyst, Contrarian, Risk Manager) with unique trading biases
+- **Consensus Mechanism:** Weighted voting based on confidence levels to determine final decisions
+- **Real-Time Updates:** SSE streaming for live debate progress
+- **Auto-Execution:** Optional automatic trade execution based on consensus
+- **Strategy Integration:** Deep integration with strategy configuration for market data and risk parameters
+- **Multi-Coin Support:** Ability to analyze and decide on multiple coins simultaneously
+
+The system enables users to leverage multiple AI perspectives for more robust trading decisions while maintaining full control over execution.

-# x402 Streaming Payment Architecture
-
-## Overview
-
-NOFX calls AI models (DeepSeek, GPT, Claude, etc.) through the claw402 gateway, using the [x402 protocol](https://github.com/coinbase/x402) to pay per request with USDC on Base L2.
-
-This document describes the full implementation of the SSE streaming call mode, including client, server, and billing logic.
-
-## Why Streaming Is Needed
-
-```
-NOFX (client)  ──→  Cloudflare (100s idle limit)  ──→  claw402 (gateway)  ──→  AI upstream
-```
-
-- DeepSeek inference takes 60–180 seconds (up to 5 minutes)
-- Cloudflare enforces a **100-second hard limit** on idle connections, returning 520/EOF on timeout
-- Non-streaming mode: the client receives no data until inference completes — Cloudflare disconnects after 100 seconds
-- Streaming mode: the first byte arrives within seconds, subsequent chunks flow continuously, keeping Cloudflare alive
-
-## End-to-End Request Flow

-### File Structure
-
-| File | Responsibility |
-|------|----------------|
-| `mcp/payment/claw402.go` | Claw402Client — model routing, wallet management |
-| `mcp/payment/x402.go` | x402 payment flow core — DoX402RequestStream, X402CallStream |
-| `mcp/client.go` | ParseSSEStream — shared SSE parsing function |
-
-### Call Chain
-
-```
-Claw402Client.Call()
-  └→ X402CallStream()                          // x402.go:380
-       ├→ Build request body + inject stream:true
-       ├→ DoX402RequestStream()                // x402.go:239
-       │    ├→ Send initial request (no payment header)
-       │    ├→ Receive 402 → parse Payment-Required header
-       │    ├→ signFn() → EIP-712 signature
-       │    └→ Send retry request with X-Payment header → return open *http.Response
-       │
-       ├→ Start idle timeout watchdog (90s with no data → disconnect)
-       ├→ TeeReader: simultaneous SSE parsing + raw byte buffering
-       ├→ ParseSSEStream()                     // client.go:703
-       │    ├→ bufio.Scanner line-by-line read
-       │    ├→ Parse "data: {...}" → OpenAI chunk format
-       │    └→ Accumulate text + call onChunk callback
-       │
-       └→ Fallback: if SSE yields nothing, try JSON parsing on buffered bodyBuf
-```
-
-### Request Identification
-
-Every request carries an `X-Client-ID: nofx` header (`x402.go:473`), allowing claw402 to identify the request source for logging and monitoring.
-
-### Model Routing
-
-`claw402ModelEndpoints` maps user-friendly model names to API paths:
-
-```go
-"deepseek"     → "/api/v1/ai/deepseek/chat"
-"gpt-5.4"      → "/api/v1/ai/openai/chat/5.4"
-"claude-opus"  → "/api/v1/ai/anthropic/messages/opus"
-"qwen-max"     → "/api/v1/ai/qwen/chat/max"
-// ... more
-```
-
-Anthropic endpoints (containing `/anthropic/`) automatically switch to the Messages API wire format.
-
-## Server Implementation (claw402)
-
-### Core Problem: ginmw Is Incompatible with SSE
-
-Coinbase's standard Gin middleware `ginmw.PaymentMiddlewareFromConfig` internally works as follows:
-
-```
-1. Wrap c.Writer with responseCapture (all writes go to buffer)
-2. c.Next() — handler runs, SSE chunks all go into buffer
-3. Settle payment after handler completes
-4. Write buffered content to client only after successful settlement
-```
-
-Problems:
-- SSE chunks are buffered — the client receives no data for minutes
-- Cloudflare disconnects after 100 seconds → 520 error
-- Handler runs too long (5 min), settlement context expires
-
-### Solution: streamAwareX402Middleware
-
-Dual-path design (`internal/gateway/x402.go`):
-
-```go
-func streamAwareX402Middleware(streamServer, standardMW) {
-    return func(c *gin.Context) {
-        if !isStreamingBody(c) {
-            standardMW(c)   // Non-streaming → standard ginmw (battle-tested)
-            return
-        }
-        // Streaming → custom path
-    }
-}
-```
-
-#### Non-Streaming Path
-
-Delegates entirely to `ginmw.PaymentMiddlewareFromConfig` with no custom logic.
-
-#### Streaming Path (Pre-Settlement)
-
-```
-1. isStreamingBody(c) — read body to check for {"stream": true}, restore body
-2. streamServer.RequiresPayment(reqCtx) — does this route require payment?
-3. streamServer.ProcessHTTPRequest() — verify X-Payment signature
-4. handleStreamingPayment():
-   a. ProcessSettlement() — settle USDC on-chain (collect payment first)
-   b. c.Next() — pass to HandleAPIKeyStream
-   c. SSE chunks write directly to c.Writer (no responseCapture buffer)
-```
-
-Key differences:
-
-| | Standard ginmw (non-streaming) | Custom path (streaming) |
-|---|---|---|
-| Settlement timing | **After** handler completes | **Before** handler starts |
-| Response buffer | `responseCapture` buffers everything | No buffer, writes directly to client |
-| Timeout risk | Slow handler causes context expiry | Settlement uses `context.Background()` |
-| SSE compatible | No | Yes |
-
-## Billing Logic
-
-### x402 Protocol Flow
-
-x402 is an HTTP 402 payment protocol proposed by Coinbase. Core roles:
-
-- **Resource Server** (claw402) — provides paid APIs
-- **Client** (NOFX) — consumer, holds an EVM wallet
-- **Facilitator** (Coinbase CDP) — verifies signatures, executes on-chain settlement
-
-### Payment Signing (EIP-712)
-
-Client signature type: USDC `TransferWithAuthorization`
-
-```
-1. Receive Payment-Required header from 402 response (base64 JSON)
-2. Decode to get:
-   - scheme: "exact"
-   - network: "eip155:8453" (Base L2)
-   - amount: USDC amount (e.g., "3000" = $0.003)
-   - asset: USDC contract address
-   - payTo: claw402 recipient address
-3. Sign with wallet private key using EIP-712, authorizing USDC transfer from user wallet to payTo
-4. Place signature in X-Payment + Payment-Signature headers
-```
-
-### Pricing Models
-
-Each AI model route has its own price configured in claw402:
-
-| Mode | Description | Example |
-|------|-------------|---------|
-| Fixed price | Specified directly via `user_price` field | `$0.003` per request |
-| Token-based dynamic pricing | Calculated from request token count | `$0.001` per 1K tokens |
-| Dispatch fallback | Default price for SDK-compatible routes | `$0.01` per request |
-
-```go
-// Fixed price
-price := fmt.Sprintf("$%s", route.UserPrice)
-
-// Dynamic pricing
-price = DynamicPriceFunc(func(ctx, reqCtx) (Price, error) {
-    return resolveDynamicPrice(ctx, reqCtx, rule)
-})
-```
-
-### Retry Logic and Double-Charge Prevention
-
-```go
-const X402MaxPaymentRetries = 5
-const X402RetryBaseWait     = 3 * time.Second
-```
-
-- **5xx errors** → exponential backoff retry (3s, 6s, 9s...), no re-signing (same payment authorization)
-- **Another 402** → previous signature expired, re-sign and retry (on-chain authorization auto-invalidates, **no double charge**)
-- **4xx (non-402)** → non-retryable, fail immediately
-- Outer retry is set to 1 (`WithMaxRetries(1)`) to prevent outer retries from causing duplicate payments
-
-### Settlement Timing: Streaming vs Non-Streaming
-
-| | Non-Streaming | Streaming |
-|---|---|---|
-| Settlement timing | After receiving full response | Before streaming begins |
-| Risk | Low (content confirmed before charge) | Slightly higher (charge before seeing content) |
-| Necessity | Standard mode | Must charge first, otherwise SSE is buffered |
-
-## Timeout Configuration
-
-| Location | Timeout | Purpose |
-|----------|---------|---------|
-| NOFX `X402Timeout` | 5 min | HTTP client overall timeout |
-| NOFX `x402StreamIdleTimeout` | 90s | SSE idle disconnect (prevent hangs) |

-## SSE Fault Tolerance
-
-### TeeReader Dual Parsing
-
-```go
-var bodyBuf bytes.Buffer
-tee := io.TeeReader(resp.Body, &bodyBuf)
-text, sseErr := ParseSSEStream(tee, onChunk, onLine)
-
-if text != "" {
-    return text, nil  // SSE succeeded
-}
-// SSE yielded nothing → try JSON parsing on bodyBuf (server may have returned non-streaming JSON)
-jsonText, _ := ParseMCPResponse(bodyBuf.Bytes())
-```
-
-### Idle Timeout Watchdog
-
-```go
-go func() {
-    t := time.NewTimer(90s)
-    for {
-        select {
-        case <-t.C:
-            cancel()  // timeout → cancel context → close TCP → body.Read() returns error
-        case <-resetCh:
-            t.Reset(90s)  // received SSE line → reset timer
-        }
-    }
-}()
-```
-
-Every incoming SSE line resets the timer. If no data arrives for 90 seconds, the context is cancelled and the TCP connection is closed, preventing indefinite blocking.

-判断は、[Claw402.ai](https://claw402.ai)・Vergex のデータスタックを読み取る言語モデルから生まれます。全市場を方向バイアスとシグナル強度でランク付けするライブシグナルボード、銘柄ごとの Signal Lab ディープシグナル、群衆の「燃料」と「壁」の位置を映すコストベース・清算ヒートマップ、リアルタイムのネットフロー — これらを生のローソク足とトレーダー自身のライブ実績と突き合わせます。ただし、執行はそうではありません。

-すべての注文は、モデルの手が届かない、コードで強制されるリスク制限を通過します。

-## モデル
-
-自分の API キーで 8 つのプロバイダーを利用できます — DeepSeek、OpenAI、Claude、Qwen、Gemini、Grok、Kimi、MiniMax。カスタムエンドポイントとカスタムモデル名にも対応しています。
-
-あるいは、キーを一切使わない方法もあります。[Claw402](https://claw402.ai) は x402 プロトコル上で、モデルの利用量を呼び出しごとに USDC で課金します。Base 上のウォレットひとつが、すべての API キーの代わりになります。
-
-| プロバイダー | アクセス |
-| :------- | :----- |
-| **Claw402** | [公式割引付きの従量課金 AI モデル](https://claw402.ai) |
-
-## マーケット
-
-9 つの取引所すべてで暗号資産の無期限先物を取引できます。Hyperliquid では、同じランタイムが暗号資産に加えて、トークン化された米国株、コモディティ、株価指数、FX、プレ IPO 無期限先物 — TSLA、NVDA、GOLD、SPX、EUR、OPENAI — も取引します。

-## インストール
-
-**Linux / macOS**
+### オプション 2: 手動インストール
 
 ```bash
+# 前提条件: Go 1.21+, Node.js 18+, TA-Lib
+
+# TA-Lib インストール (macOS)
+brew install ta-lib
+
+# クローンとセットアップ
+git clone https://github.com/NoFxAiOS/nofx.git
+cd nofx
+go mod download
+cd web && npm install && cd ..
+
+# バックエンド起動
+go build -o nofx && ./nofx
+
+# フロントエンド起動（新しいターミナル）
+cd web && npm run dev
+```
+
+---
+
+## 初期設定
+
+1. **AI モデル設定** - AI API キーを追加
+2. **取引所設定** - 取引所 API 認証情報を設定
+3. **戦略作成** - ストラテジースタジオで取引戦略を設定
+4. **トレーダー作成** - AI モデル + 取引所 + 戦略を組み合わせ
+5. **取引開始** - 設定したトレーダーを起動
+
+---
+
+## リスク警告
+
+1. 暗号通貨市場は非常に変動が激しい - AI の決定は利益を保証しない
+2. 先物取引はレバレッジを使用 - 損失は元本を超える可能性がある
+3. 極端な市場状況では清算リスクがある
+
+---
+
+## サーバー展開
+
+### クイックデプロイ (HTTP経由のIP)
+
+デフォルトでは、トランスポート暗号化は**無効**になっており、HTTPSなしでIPアドレス経由でNOFXにアクセスできます:
+
+```bash
+# サーバーにデプロイ
 curl -fsSL https://raw.githubusercontent.com/NoFxAiOS/nofx/main/install.sh | bash
 ```
 
-**Railway**
+`http://YOUR_SERVER_IP:3000` 経由でアクセス - すぐに動作します。
 
-[![Deploy on Railway](https://railway.com/button.svg)](https://railway.com/deploy/nofx?referralCode=nofx)
+### セキュリティ強化 (HTTPS)
 
-**Docker**
+セキュリティを強化するには、`.env`でトランスポート暗号化を有効にします:
 
 ```bash
-curl -O https://raw.githubusercontent.com/NoFxAiOS/nofx/main/docker-compose.prod.yml
-docker compose -f docker-compose.prod.yml up -d
+TRANSPORT_ENCRYPTION=true
 ```
 
-**Windows** — [Docker Desktop](https://www.docker.com/products/docker-desktop/) をインストールしてから、次を実行します。
+有効にすると、ブラウザはWeb Crypto APIを使用して転送前にAPIキーを暗号化します。これには以下が必要です:
+- `https://` - SSLを備えた任意のドメイン
+- `http://localhost` - ローカル開発
 
-```powershell
-curl -o docker-compose.prod.yml https://raw.githubusercontent.com/NoFxAiOS/nofx/main/docker-compose.prod.yml
-docker compose -f docker-compose.prod.yml up -d
-```
+### Cloudflareを使用した簡単なHTTPSセットアップ
 
-**ソースからビルド** — Go 1.21+、Node.js 18+ が必要です。
+1. **ドメインをCloudflareに追加** (無料プランでOK)
+   - [dash.cloudflare.com](https://dash.cloudflare.com) にアクセス
+   - ドメインを追加してネームサーバーを更新
 
+2. **DNSレコードを作成**
+   - タイプ: `A`
+   - 名前: `nofx` (またはサブドメイン)
+   - コンテンツ: サーバーのIP
+   - プロキシ状態: **Proxied** (オレンジ色の雲)
+
+3. **SSL/TLSを設定**
+   - SSL/TLS設定に移動
+   - 暗号化モードを **Flexible** に設定
+
+   ```
+   User ──[HTTPS]──→ Cloudflare ──[HTTP]──→ Your Server:3000
+   ```
+
+4. **トランスポート暗号化を有効化**
+   ```bash
+   # .envを編集して設定
+   TRANSPORT_ENCRYPTION=true
+   ```
+
+5. **完了!** `https://nofx.yourdomain.com` 経由でアクセス
+
+---
+
+## 初期設定 (Webインターフェース)
+
+システムを起動した後、Webインターフェースを通じて設定します:
+
+1. **AIモデルの設定** - AI APIキーを追加 (DeepSeek、OpenAI など)
+2. **取引所の設定** - 取引所API認証情報を設定
+3. **戦略の作成** - ストラテジースタジオで取引戦略を設定
+4. **トレーダーの作成** - AIモデル + 取引所 + 戦略を組み合わせ
+5. **取引開始** - 設定したトレーダーを起動
+
+すべての設定はWebインターフェースで完了 - JSONファイルの編集は不要です。
+
+---
+

+## AI 기반 암호화폐 거래 플랫폼
 
-NOFX는 언어 모델이 곧 전략이 되는 오픈소스 트레이딩 터미널입니다. 각 트레이더는 시장 구조 읽기, 판단, 실행, 근거 기록으로 이어지는 루프를 끊임없이 반복하고, Go 런타임은 모든 주문을 모델이 절대 우회할 수 없는 하드 리스크 한도 안에 묶어 둡니다.
+**NOFX**는 여러 AI 모델을 실행하여 암호화폐 선물을 자동으로 거래할 수 있는 오픈소스 AI 거래 시스템입니다. 웹 인터페이스를 통해 전략을 구성하고, 실시간으로 성과를 모니터링하며, AI 에이전트들이 최적의 거래 방식을 찾도록 경쟁시킵니다.
 
-트레이더는 자유롭게 조합할 수 있습니다. 어떤 모델이든, 아홉 개 거래소 중 어디든, 어떤 전략이든 가능합니다. 여러 트레이더를 나란히 돌리면서 실현 수익률 기준의 공개 리더보드에서 비교해 보세요. 모든 것은 사용자의 머신에서 실행되며, 거래소 자격 증명은 저장 시 암호화되고 절대 외부로 나가지 않습니다.
+### 핵심 기능
+
+- **다중 AI 지원**: DeepSeek, Qwen, GPT, Claude, Gemini, Grok, Kimi 실행 - 언제든 모델 전환 가능
+- **다중 거래소**: Binance, Bybit, OKX, Hyperliquid, Aster DEX, Lighter에서 통합 거래
+- **전략 스튜디오**: 코인 소스, 지표, 리스크 제어를 설정하는 시각적 전략 빌더
+- **AI 경쟁 모드**: 여러 AI 트레이더가 실시간으로 경쟁, 성과를 나란히 추적
+- **웹 기반 설정**: JSON 편집 불필요 - 웹 인터페이스에서 모든 설정 완료
+- **실시간 대시보드**: 실시간 포지션, 손익 추적, 사고의 연쇄가 포함된 AI 결정 로그

+## 빠른 시작
+
+### 옵션 1: Docker 배포 (권장)
+
+```bash
+git clone https://github.com/NoFxAiOS/nofx.git
+cd nofx
+chmod +x ./start.sh
+./start.sh start --build
+```
+
+웹 인터페이스 접속: **http://localhost:3000**
+
+### 최신 버전 유지
+
+> **💡 업데이트가 빈번합니다.** 최신 기능과 수정 사항을 받으려면 매일 이 명령을 실행하세요:
 
 ```bash
 curl -fsSL https://raw.githubusercontent.com/NoFxAiOS/nofx/main/install.sh | bash
 ```
 
-터미널은 `http://127.0.0.1:3000`에서 열립니다.
+이 명령은 최신 공식 이미지를 가져오고 서비스를 자동으로 다시 시작합니다.
 
-**첫 실행**
-
-1. 계정을 등록합니다 — 첫 번째 계정이 해당 인스턴스의 소유자가 됩니다.
-2. 가이드 런치를 따라갑니다. 자동으로 생성된 AI 수수료 지갑에 **$1+ USDC**(Base 네트워크)를 넣은 뒤, Hyperliquid를 연결하고 거래 자금으로 **$12+ USDC**를 입금합니다.
-3. **Autopilot**을 시작합니다. AI가 몇 분마다 시장을 스캔하며 스스로 거래하고, 모든 결정은 발생하는 즉시 대시보드에 표시됩니다. 언제든 클릭 한 번으로 중지할 수 있습니다.

-## 모델은 제안하고, 런타임이 결정합니다
-
-의사결정은 [Claw402.ai](https://claw402.ai) · Vergex 데이터 스택을 읽는 언어 모델에서 나옵니다. 모든 시장을 방향 편향과 시그널 강도로 순위 매기는 실시간 시그널 보드, 종목별 Signal Lab 딥 시그널, 시장의 '연료'와 '벽'이 어디에 있는지 보여주는 코스트·청산 히트맵, 실시간 순유입 — 이를 원시 캔들과 트레이더 자신의 실시간 트랙 레코드로 교차 검증합니다. 그러나 실행은 그렇지 않습니다.
-
-모든 주문은 모델의 손이 닿지 않는 곳에서 코드로 강제되는 한도를 통과해야 합니다.
-
-|                          |                                                                                    |
-| :----------------------- | :--------------------------------------------------------------------------------- |
-| 포지션 한도          | 최대 동시 포지션 수, 자본 대비 비율로 상한이 걸린 명목 금액, 심볼당 포지션 1개 |
-| 레버리지 클램프          | 모델이 무엇을 요청하든 관계없이 주문 크기 산정 시점에 적용되는 하드 캡     |
-| 거래소 측 보호 | 모든 진입 직후 거래소에 스탑로스와 테이크프로핏을 즉시 배치     |
-| 드로다운 자동 청산      | 고점 대비 이익을 과도하게 반납한 수익 포지션은 자동으로 청산            |
-| 거래 스로틀링         | 최소 보유 시간, 심볼별 재진입 쿨다운, 사이클당·시간당 진입 횟수 제한 |
-| 세이프 모드                | 모델 오류가 반복되면 모델이 복구될 때까지 신규 진입을 차단                 |
-| 런치 프리플라이트         | 트레이더 시작 전에 모델 접근성, 지갑 자금, 전략, 거래소 잔고를 검증 |
-
-각 결정은 모델의 전체 추론 과정과 함께 저장됩니다. 기록 없는 포지션은 존재하지 않습니다.

-## 모델
-
-자신의 키로 사용할 수 있는 여덟 개 제공업체 — DeepSeek, OpenAI, Claude, Qwen, Gemini, Grok, Kimi, MiniMax — 커스텀 엔드포인트와 모델 이름도 지원합니다.
-
-키가 전혀 없어도 됩니다. [Claw402](https://claw402.ai)는 x402 프로토콜을 통해 모델 사용량을 호출 단위로 USDC로 정산합니다. Base 네트워크의 지갑 하나가 모든 API 키를 대신합니다.
-
-| 제공업체 | 이용 방법 |

-
-## 시장
-
-아홉 개 거래소 전체에서 암호화폐 무기한 선물을 거래합니다. Hyperliquid에서는 같은 런타임이 암호화폐와 함께 토큰화된 미국 주식, 원자재, 지수, 외환, 프리 IPO 무기한 선물 — TSLA, NVDA, GOLD, SPX, EUR, OPENAI — 도 거래합니다.

-## 설치
-
-**Linux / macOS**
+### 옵션 2: 수동 설치
 
 ```bash
+# 필수 조건: Go 1.21+, Node.js 18+, TA-Lib
+
+# TA-Lib 설치 (macOS)
+brew install ta-lib
+
+# 클론 및 설정
+git clone https://github.com/NoFxAiOS/nofx.git
+cd nofx
+go mod download
+cd web && npm install && cd ..
+
+# 백엔드 시작
+go build -o nofx && ./nofx
+
+# 프론트엔드 시작 (새 터미널)
+cd web && npm run dev
+```
+
+---
+
+## 초기 설정
+
+1. **AI 모델 설정** - AI API 키 추가
+2. **거래소 설정** - 거래소 API 자격 증명 설정
+3. **전략 생성** - 전략 스튜디오에서 거래 전략 구성
+4. **트레이더 생성** - AI 모델 + 거래소 + 전략 조합
+5. **거래 시작** - 설정된 트레이더 시작
+
+---
+
+## 위험 경고
+
+1. 암호화폐 시장은 매우 변동성이 높음 - AI 결정이 수익을 보장하지 않음
+2. 선물 거래는 레버리지 사용 - 손실이 원금을 초과할 수 있음
+3. 극단적인 시장 상황에서 청산 위험 있음
+
+---
+
+## 서버 배포
+
+### 빠른 배포 (IP를 통한 HTTP)
+
+기본적으로 전송 암호화가 **비활성화**되어 HTTPS 없이 IP 주소를 통해 NOFX에 액세스할 수 있습니다:
+
+```bash
+# 서버에 배포
 curl -fsSL https://raw.githubusercontent.com/NoFxAiOS/nofx/main/install.sh | bash
 ```
 
-**Railway**
+`http://YOUR_SERVER_IP:3000`을 통해 액세스 - 즉시 작동합니다.
 
-[![Deploy on Railway](https://railway.com/button.svg)](https://railway.com/deploy/nofx?referralCode=nofx)
+### 향상된 보안 (HTTPS)
 
-**Docker**
+보안을 강화하려면 `.env`에서 전송 암호화를 활성화하세요:
 
 ```bash
-curl -O https://raw.githubusercontent.com/NoFxAiOS/nofx/main/docker-compose.prod.yml
-docker compose -f docker-compose.prod.yml up -d
+TRANSPORT_ENCRYPTION=true
 ```
 
-**Windows** — [Docker Desktop](https://www.docker.com/products/docker-desktop/)을 설치한 뒤:
+활성화되면 브라우저는 Web Crypto API를 사용하여 전송 전에 API 키를 암호화합니다. 이를 위해 필요한 것:
+- `https://` - SSL이 있는 모든 도메인
+- `http://localhost` - 로컬 개발
 
-```powershell
-curl -o docker-compose.prod.yml https://raw.githubusercontent.com/NoFxAiOS/nofx/main/docker-compose.prod.yml
-docker compose -f docker-compose.prod.yml up -d
-```
+### Cloudflare를 사용한 빠른 HTTPS 설정
 
-**소스에서 빌드** — Go 1.21+, Node.js 18+:
+1. **Cloudflare에 도메인 추가** (무료 플랜 가능)
+   - [dash.cloudflare.com](https://dash.cloudflare.com) 방문
+   - 도메인 추가 및 네임서버 업데이트
 
+2. **DNS 레코드 생성**
+   - 유형: `A`
+   - 이름: `nofx` (또는 서브도메인)
+   - 콘텐츠: 서버 IP
+   - 프록시 상태: **Proxied** (주황색 구름)
+
+3. **SSL/TLS 구성**
+   - SSL/TLS 설정으로 이동
+   - 암호화 모드를 **Flexible**로 설정
+
+   ```
+   User ──[HTTPS]──→ Cloudflare ──[HTTP]──→ Your Server:3000
+   ```
+
+4. **전송 암호화 활성화**
+   ```bash
+   # .env 편집 및 설정
+   TRANSPORT_ENCRYPTION=true
+   ```
+
+5. **완료!** `https://nofx.yourdomain.com`을 통해 액세스
+
+---
+
+## 초기 설정 (웹 인터페이스)
+
+시스템을 시작한 후 웹 인터페이스를 통해 구성합니다:
+
+1. **AI 모델 구성** - AI API 키 추가 (DeepSeek, OpenAI 등)
+2. **거래소 구성** - 거래소 API 자격 증명 설정
+3. **전략 생성** - 전략 스튜디오에서 거래 전략 구성
+4. **트레이더 생성** - AI 모델 + 거래소 + 전략 결합
+5. **거래 시작** - 구성된 트레이더 시작
+
+모든 구성은 웹 인터페이스를 통해 완료 - JSON 파일 편집 불필요.
+
+---
+
+## 웹 인터페이스 기능
+
+### 경쟁 페이지
+- 실시간 ROI 리더보드
+- 다중 AI 성능 비교 차트
+- 실시간 손익 추적 및 순위
+
+### 대시보드
+- TradingView 스타일 캔들스틱 차트
+- 실시간 포지션 관리
+- Chain of Thought 추론이 포함된 AI 결정 로그
+- 자본 곡선 추적
+
+### 전략 스튜디오
+- 코인 소스 구성 (정적 목록, AI500 풀, OI Top)
+- 기술 지표 (EMA, MACD, RSI, ATR, 거래량, OI, 펀딩 비율)
+- 리스크 제어 설정 (레버리지, 포지션 한도, 마진 사용)
+- 실시간 프롬프트 미리보기를 포함한 AI 테스트
+
+---
+
+## 일반적인 문제
+
+### TA-Lib을 찾을 수 없음
 ```bash
-git clone https://github.com/NoFxAiOS/nofx.git && cd nofx
-go build -o nofx && ./nofx            # backend
-cd web && npm install && npm run dev  # frontend, in a second terminal
+# macOS
+brew install ta-lib
+
+# Ubuntu
+sudo apt-get install libta-lib0-dev
 ```
 
-**업데이트** — 설치 스크립트를 다시 실행하면 제자리에서 업그레이드됩니다.
+### AI API 타임아웃
+- API 키가 올바른지 확인
+- 네트워크 연결 확인
+- 시스템 타임아웃은 120초
 
-<details>
-<summary>서버 배포</summary>
+### 프론트엔드가 백엔드에 연결할 수 없음
+- 백엔드가 http://localhost:8080에서 실행 중인지 확인
+- 포트가 점유되어 있지 않은지 확인

-
-**HTTP**
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/NoFxAiOS/nofx/main/install.sh | bash
-# http://YOUR_IP:3000
-```
-
-**Cloudflare를 통한 HTTPS**
-
-1. [Cloudflare](https://dash.cloudflare.com)에 도메인 추가(무료 플랜)
-2. A 레코드 → 서버 IP, Proxied 설정
-3. SSL/TLS → Flexible
-4. `.env`에 `TRANSPORT_ENCRYPTION=true` 설정
