Structure Flow Swing Strategy v4.0
Structure Flow Swing Strategy v4.1
==================================
15m 震荡区间波段策略 — 基于价格聚集度检测
15m 震荡波段 — 基于"碰壁验证"价格聚集度检测（短窗口版）
核心变革（相对于 v3.x）：
1. 时间框架从 4H → 15m：直接在小周期检测和执行
2. 震荡判定从 "swing points 宽度稳定性" → "价格聚集度 + 边界测试次数"
3. 检测周期 4-8 小时即可识别震荡，覆盖 1-3 天的 mini-震荡
v3.1 诊断回顾（2026-06-10 全周期回测）：
- 122笔全部做空，+76%，CAGR 10.97%
- is_ranging 仅 13.7%，用 4H 判定只抓到大周期震荡
- 1-3 天的小震荡完全被漏掉，这才是手工交易的利润来源
版本历史：
v3.0 (2026-06-10): 初版，4H swing points + 双边测试
v3.1 (2026-06-10): AND→OR，降门槛
v4.0 (2026-06-10): 全面重写，15m 价格聚集度检测
v4.1b (2026-06-10): 1H + 3K线验证（正收益但频率太低）
v4.1c (2026-06-10): 回到15m + 缩短lookback至24根(6h) + 保留min_rejections=2
