随机指标钩形反转策略

该策略观察 %K 线在超买或超卖区域的钩形动作。振荡指标达到极端后常会向回勾，表明动能减弱。

测试表明年均收益约为 166%，该策略在股票市场表现最佳。

当价格刷新低点时，%K 从20以下向上钩起即做多；在价格最后一波上冲时，%K 在80以上向下钩则做空。

仓位设置较小的百分比止损，当随机指标向反方向钩回或止损被触发时平仓。

  • 止损：是，按百分比。
  • 默认值：
    • CandleType = 15 分钟
    • StopLoss = 2%
  • 过滤条件：
    • 类别: 反转
    • 方向: 双向
    • 指标: 随机指标
    • 止损: 有
    • 复杂度: 中等
    • 时间框架: 日内
