-    反转策略：RSI 2-24 → PCA → 模型预测 → 极端值反向开仓
-    开仓：下一根 Open 价挂限价单
-    平仓：满足以下任一条件后市价平仓
-        1. 价格触及固定价差止损线
-        2. 持有满 holding_bars 根 K 线
+    一个最简单的RSI交易策略。
+
+    核心哲学:
+    1. 动量跟踪: 遵循RSI指标反映的市场动量。RSI高于60被视为强势市场，
+       适合做多；低于40被视为弱势市场，适合做空。
+    2. 信号持续则持仓: 与传统的“超买/超卖”反转逻辑不同，本策略认为只要
+       市场维持强势（RSI > 60）或弱势（RSI < 40），就应该继续持有仓位，
+       直到出现明确的反转信号。
+    3. 简单的风险控制: 不设置固定的止盈目标，让利润自由发展。只设置一个
+       基于ATR的动态止损，用于管理最基本的下行风险。
