+Structure Flow Swing Strategy v3.1
+==================================
+波段交易策略 — 基于4H震荡区间，保守参数 v2
+
+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
+
+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）
+
+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
