Structure Flow Strategy v1.6
|
||||
=======================
|
||||
变更记录：
|
||||
v1.0 (2026-06-07): 纯价格结构策略，D1定方向→4H定位→1H入场
|
||||
v1.1 (2026-06-07): 1H futures，结构止损，首次回测成功(+61.52%)
|
||||
v1.2 (2026-06-07): Entry Candle止损，bug导致50笔硬止损全亏
|
||||
v1.3 (2026-06-07): ATR动态止损，结果-63.72%，胜率20.2%
|
||||
v1.4 (2026-06-07): 回归纯价格结构止损，+140.71%，胜率38.7%
|
||||
v1.5 (2026-06-07): 参数调优(stoploss -5%→-15%, max_stop_dist 3%→5%)，+140.83%
|
||||
v1.6 (2026-06-07): ===== 入场质量优化 =====
|
||||
- 6-bar冷却期：信号后6h内不重复入场（防止连挨多刀）
|
||||
- 活支撑/阻力检查：S/R必须被最近测试并守住才算有效
|
||||
设计原则：不降频，只砍最差的那几笔重复入场
