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
