v1.6 (2026-06-07): ===== 入场质量优化 =====
|
v1.6 (2026-06-07): 入场质量优化(冷却期+活支撑),+151.32% ⭐ 最优基线
|
||||||
- 6-bar冷却期:信号后6h内不重复入场(防止连挨多刀)
|
v1.7 (2026-06-07): 止损优化(5%缓冲),❌ 失败
|
||||||
- 活支撑/阻力检查:S/R必须被最近测试并守住才算有效
|
v1.8 (2026-06-07): 止损优化(2%缓冲),❌ 失败
|
||||||
设计原则:不降频,只砍最差的那几笔重复入场
|
v1.9 (2026-06-08): ===== 结构变化检测止损 =====
|
||||||
v1.6.4 (2026-06-08): ===== 止损距离下限过滤器 =====
|
入场逻辑保持 v1.6 不变。
|
||||||
- 核心发现:交叉对比 v1.6 的 stop_loss vs trailing_stop_loss
|
custom_stoploss 新增:当价格已穿越原 S/R 时,
|
||||||
止损距离是最大区分因子!
|
提前退出而非等待原止损位。
|
||||||
LONG: stop_loss 2.08% vs trailing_stop 3.06% (+47%)
|
核心假设:入场后 S/R 被否定 → 原止损逻辑无效。
|
||||||
SHORT: stop_loss 1.80% vs trailing_stop 2.10% (+17%)
|
|
||||||
- 根因:止损设太近 → 被噪音震出 → 错过 trailing_stop 利润
|
|
||||||
- 改动:min_stop_dist 从 0.3% 提升到 2.0%
|
|
||||||
LONG: 要求 support_4h 距离入场价至少 2%
|
|
||||||
SHORT: 要求 resistance_4h 距离入场价至少 2%
|
|
||||||
- 预期:减少在窄止损距离上的入场 → 降低 stop_loss 比例
|
|
||||||
但也会过滤掉部分窄止损但最终盈利的交易

v1.9改动(相对于v1.6):

基于交叉对比分析发现止损距离是最大区分因子:

custom_stoploss 增加结构变化检测:

- 盈利交易止损距离平均比亏损交易宽 30-50%
|
- 做多:如果当前 bar 的 close < support_4h(支撑被跌破),提前退出
|
||||||
- LONG stop_loss 65% 止损距离 <2%,trailing_stop 62% >2%
|
- 做空:如果当前 bar 的 close > resistance_4h(阻力被突破),提前退出
|

→ 新增 min_stop_dist 参数,默认 2%,拒绝止损距离过近的入场
|
