-# 网格策略市场状态识别与风控设计
-
-## 概述
-
-增强网格策略的市场状态识别能力，实现震荡/趋势的精准判断，并根据不同震荡级别自动调整网格参数和风控策略。
-
----
-
-## 一、市场状态识别
-
-### 1.1 识别维度（3个）
-
-| 维度 | 指标 | 作用 |
-|------|------|------|
-| 价格波动 | ATR14 + Bollinger带宽 | 判断震荡幅度 |
-| 趋势强度 | EMA20/50距离 + MACD | 判断是否有趋势 |
-| 动量 | RSI14 + 1h/4h涨跌幅 | 判断超买超卖 |
-
-### 1.2 箱体指标（新增）
-
-基于1小时K线的多周期Donchian通道：
-
-| 箱体级别 | 周期 | 覆盖时间 | 用途 |
-|----------|------|----------|------|
-| 短期箱体 | 72根1小时 | 3天 | 日内波动边界 |
-| 中期箱体 | 240根1小时 | 10天 | 周级别震荡区间 |
-| 长期箱体 | 500根1小时 | ~21天 | 大级别趋势边界 |
-
-### 1.3 判断方式
-
-由AI综合分析以上指标 + 原始K线序列 + 箱体位置，输出市场状态判断。
-
----
-
-## 二、震荡分级与网格策略
-
-### 2.1 四级震荡分类
-
-| 级别 | 特征 | 判断依据 |
-|------|------|----------|
-| 窄幅震荡 | 价格在短期箱体内小幅波动 | Bollinger带宽 < 2%，ATR低 |
-| 标准震荡 | 价格在中期箱体内正常波动 | Bollinger带宽 2-3%，ATR正常 |
-| 宽幅震荡 | 价格接近中期箱体边缘 | Bollinger带宽 3-4%，ATR较高 |
-| 剧烈震荡 | 价格接近长期箱体边缘 | Bollinger带宽 > 4%，ATR高 |
-
-### 2.2 各级别对应的网格策略
-
-| 级别 | 网格密度 | 网格范围 | 单格仓位 | 总仓位上限 | 有效杠杆上限 |
-|------|----------|----------|----------|------------|--------------|
-| 窄幅震荡 | 密集 | 窄 | 小 | 30-40% | 2x |
-| 标准震荡 | 正常 | 中等 | 正常 | 60-70% | 3-4x |
-| 宽幅震荡 | 稀疏 | 宽 | 正常 | 50-60% | 3x |
-| 剧烈震荡 | 最稀疏 | 最宽 | 小 | 30-40% | 2x |
-
-**核心原则：**
-- 窄幅震荡：单格仓位小 + 总仓位上限低（防击穿风险）
-- 剧烈震荡：同样保守（随时可能变趋势）
-- 标准震荡：才是放量的最佳时机
-
----
-
-## 三、突破处理与恢复机制
-
-### 3.1 突破判断与处理
-
-**确认方式：** 收盘价突破箱体后，持续3根1小时K线不回箱体
-
-| 箱体级别 | 突破处理 |
-|----------|----------|
-| 短期箱体突破 | 降低仓位到 50% |
-| 中期箱体突破 | 暂停网格 + 取消挂单 |
-| 长期箱体突破 | 暂停网格 + 取消挂单 + 平掉所有持仓 |
-
-### 3.2 假突破恢复
-
-**价格回到箱体内 → 以50%仓位恢复网格**
-
----
-
-## 四、前端风控面板
-
-### 4.1 需要展示的信息
-
-| 类别 | 显示内容 |
-|------|----------|
-| 杠杆信息 | 当前杠杆、有效杠杆、系统推荐杠杆 |
-| 仓位信息 | 当前仓位、最大仓位、仓位占比 |
-| 爆仓信息 | 爆仓价格、爆仓距离(%) |
-| 市场状态 | 当前震荡级别(窄幅/标准/宽幅/剧烈) |
-| 箱体状态 | 短期/中期/长期箱体上下沿、当前价格位置 |

-   - `ShortBoxUpper/Lower` - 短期箱体上下沿
-   - `MidBoxUpper/Lower` - 中期箱体上下沿
-   - `LongBoxUpper/Lower` - 长期箱体上下沿
-   - `BreakoutStatus` - 突破状态 (none/short/mid/long)

-## 六、风险控制总结
-
-| 控制点 | 机制 |
-|--------|------|
-| 仓位控制 | 根据震荡级别限制总仓位上限 (30-70%) |
-| 杠杆控制 | 根据震荡级别限制有效杠杆 (2-4x) |
-| 突破保护 | 三级箱体突破分级处理 |
-| 假突破恢复 | 50%仓位降级恢复 |
-| 爆仓预防 | 前端展示爆仓距离，系统自动限制杠杆 |

-## 网格配置
-- 交易对: %s
-- 网格层数: %d
-- 总投资: %.2f USDT
-- 杠杆: %dx
-- 价格分布: %s
-
-## 决策规则
-
-### 市场状态判断
-- **震荡市场** (适合网格): 布林带宽度 < 3%%, EMA20/50 距离 < 1%%, 价格在布林带中轨附近
-- **趋势市场** (暂停网格): 布林带宽度 > 4%%, EMA20/50 距离 > 2%%, 价格持续突破布林带
-- **高波动市场** (谨慎): ATR异常放大, 价格剧烈波动
-
-### 可执行的操作
-- place_buy_limit: 在指定价格下买入限价单
-- place_sell_limit: 在指定价格下卖出限价单
-- cancel_order: 取消指定订单
-- cancel_all_orders: 取消所有订单
-- pause_grid: 暂停网格交易（趋势市场时）
-- resume_grid: 恢复网格交易（震荡市场时）
-- adjust_grid: 调整网格边界

-- **High Volatility** (caution): ATR spike, erratic price movement
-
-### Available Actions
-- place_buy_limit: Place buy limit order at specified price
-- place_sell_limit: Place sell limit order at specified price
-- cancel_order: Cancel specific order
-- cancel_all_orders: Cancel all orders
-- pause_grid: Pause grid trading (in trending market)
-- resume_grid: Resume grid trading (in ranging market)
-- adjust_grid: Adjust grid boundaries
-- hold: Maintain current state
