-Structure Flow Swing Strategy v4.2
+Structure Flow Scalp — 震荡市剥头皮策略
-==================================
+==========================================
-纯价格行为学震荡策略 — 借鉴 v2.2b 的 swing point + K线形态框架
+基于Al Brooks价格行为学：
+- 在已识别的震荡区间内，支撑位做多、阻力位做空
+- 15m级别支撑/阻力决定交易区间，5m级别入场
+- 100x全仓杠杆，每次10%仓位
+- 区间高度40%止盈，15m支撑/阻力外侧0.3%止损
 
-核心逻辑（模拟手工交易）：
+变更记录：
-1. 用 swing point 识别近期高低点，自动形成交易区间
+   v1 (2026-06-10): 初版，基于v2.2b核心逻辑重构
-2. 价格到支撑 + K线止跌形态（bullish pinbar/engulfing）→ 做多
+   v1.1 (2026-06-10): 支撑阻力从4H改为15m
-3. 价格到阻力 + K线滞涨 → 平多（反向开空同理）
+   v1.2 (2026-06-10): 去掉4H趋势强度判断（冗余）；启用100x全仓杠杆，10%仓位
-4. 不在震荡判定上设严苛门槛，价格够到边界+形态确认就做
+   v1.3 (2026-06-10): 代码审查修复——移除populate_exit_trend死循环，NaN安全，杠杆上限
-5. 趋势突破时，突破边界导致亏损，但可控
+   v1.4 (2026-06-10): EMA动态S/R + 入场锁定S/R——止损止盈使用入场时的锁定值，不追最新
-
+   v1.5 (2026-06-10): 扩展入场信号 + 追踪止损保护 + 延长活S/R窗口
-v4.1 系列教训（2026-06-10）：
+   v1.6 (2026-06-10): 止损改为ATR动态计算——绑入场价，不绑支撑位；追踪改为ATR×0.5自适应
-  用滚动window + 碰壁验证 + ATR比例止损 → 全是技术指标思维，不是价格行为学
-  唯一正收益的是最简单的版本（1H + 形态 + 固定-3%止损）
