+# Market Regime Classification Framework
+
+> A comprehensive market state identification system for quantitative trading strategy matching
+
+---
+
+## 1. Classification Dimensions Overview
+
+Market state identification requires analysis across multiple dimensions:
+
+| Dimension | Sub-dimensions | Description |
+|-----------|---------------|-------------|
+| **Trend** | Direction, Strength | Determine market movement direction and momentum |
+| **Volatility** | Amplitude, Frequency | Measure price fluctuation characteristics |
+| **Structure** | Pattern, Phase | Identify market structure and cycle position |
+
+---
+
+## 2. Primary Classification (5 Categories)

+
+### 2.2 Identification Indicators
+

+  - ADX > 25: Clear trend exists
+  - ADX < 20: Range-bound market
+- **EMA Alignment**: Determines trend direction
+  - EMA20 > EMA50 > EMA200: Bullish alignment

+# 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 |
+
+---
+
+## 五、实现要点
+
+### 5.1 后端新增
+
+1. **箱体指标计算** (`market/data.go`)
+   - 新增 `calculateDonchian(klines, period)` 函数
+   - 返回 upper(最高价), lower(最低价)
+   - 支持72/240/500三个周期
+
+2. **市场状态评估** (`kernel/grid_engine.go`)
+   - 更新AI prompt，加入箱体指标和K线序列
+   - AI输出震荡级别判断
+
+3. **网格参数动态调整** (`trader/auto_trader_grid.go`)
+   - 根据震荡级别自动调整：网格密度、范围、仓位、杠杆
+   - 实现有效杠杆上限控制
+
+4. **突破处理逻辑** (`trader/auto_trader_grid.go`)
+   - 实现三级箱体突破检测
+   - 实现3根K线确认逻辑
+   - 实现降级恢复机制
+
+### 5.2 前端新增
+
+1. **风控面板组件**
+   - 杠杆信息展示
+   - 仓位信息展示
+   - 爆仓信息展示
+   - 市场状态展示
+   - 箱体状态可视化
+
+### 5.3 数据模型更新
+
+1. **GridConfigModel** 新增字段：
+   - `EffectiveLeverageLimit` - 有效杠杆上限
+   - `ShortBoxPeriod` - 短期箱体周期 (默认72)
+   - `MidBoxPeriod` - 中期箱体周期 (默认240)
+   - `LongBoxPeriod` - 长期箱体周期 (默认500)
+
+2. **GridInstanceModel** 新增字段：
+   - `CurrentRegimeLevel` - 当前震荡级别 (narrow/standard/wide/volatile)
+   - `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)
+   - `BreakoutConfirmCount` - 突破确认K线计数
+
+---
+
+## 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 |

+1. 判断当前市场状态（震荡/趋势/高波动）
+2. 决定是否需要调整网格或暂停交易
+3. 管理每个网格层级的订单
+
+## 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
+- hold: 保持当前状态不操作

+- **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
