Structure Flow Swing Strategy v3.1
Structure Flow Swing Strategy v3.2
==================================
波段交易策略 — 基于4H震荡区间保守参数 v2
波段交易策略 — 基于4H震荡区间v3.1优化版
v3.1 改动基于v3.0诊断结果):
1. 双边测试 AND→OR在10根K线内测试过支撑 OR 阻力即可(不需两者都测过)
2. 区间稳定性 15%→25%:放宽波动容忍度
3. 入场范围 2%→3%:增加候选信号密度
4. 冷却期 3根→1根减少过渡过滤
v3.2 改动基于v3.1诊断结果 — 三大市场感知不足
1. D1趋势强度过滤D1处于强趋势时拒绝入场防假区间陷阱
- 计算 D1 EMA20/EMA50 间距作为趋势强度指标
- 趋势强度超过阈值 → 不交易即使4H出现区间形态
2. 区间质量评分:从二分法升级为多维度评分
- 边界测试次数(测试越多越可靠)
- 区间持续时长(越长越成熟)
- 区间宽度适配度3-8%最优)
- 总分>=阈值才入场
3. 主动退出机制:确认转趋势后提前离场
- 3根连续K线收盘在入场时区间外 → 结构破坏
- 不等止损,主动离场(仅在损失<2%时)
- 避免浮盈变亏损
保留纯震荡定位、ATR×1.5止损、区间70%止盈、D1趋势过滤
预期年交易量从9笔 → 50-80笔约1-2单/周)
保留纯震荡定位、ATR×1.5止损、区间70%止盈、OR双边测试、冷却期1根
版本历史:
v3.0 (2026-06-10): 初版,基于冯总波段交易新思路
v3.1 (2026-06-10): 降低条件门槛,提升交易频率
v3.1 (2026-06-10): 降低条件门槛,AND→OR等4项
v3.2 (2026-06-10): 三大市场感知改进
