Structure Flow Strategy v2.2c — 冷却期修复版 Structure Flow Swing Strategy v3.0
============================================== ==================================
变更记录: 波段交易策略 — 基于4H震荡区间保守参数
v2.2c (2026-06-11): 1H S/R 替代 4H S/R
v2.2c-coolfix (2026-06-11): 修复冷却期无限阻止下单 bug 核心思路(冯总指示):
1. 在4H级别识别震荡区间
2. 只在确认震荡时交易(区间宽度稳定、价格测试过边界、无突破)
3. 止损设在支撑/阻力外侧,确保几乎不被噪音触发
4. 止损被触发 = 结构已坏,离场正确
5. 止盈区间高度的70%
保守参数:
- 杠杆1x无杠杆
- 止损安全边际ATR(4H, 14) * 1.5
- 区间宽度稳定阈值15%
- 止盈区间70%
- 入场范围:支撑/阻力2%以内
版本历史:
v3.0 (2026-06-10): 初版,基于冯总波段交易新思路
