Hull 均线反转策略

Hull 移动平均在保持平滑的同时对价格变化反应迅速，其方向的变化往往预示短期反转。本策略监控连续的 Hull MA 值，当斜率翻转时入场。

测试表明年均收益约为 154%，该策略在股票市场表现最佳。

当均线由下行转为上行时做多；由上行转为下行时做空。风险通过基于 ATR 的止损控制，止损放在最近蜡烛之外。

离场依靠该保护性止损，捕捉 Hull MA 指示动能转向后的部分走势。

细节

  • 止损：有，基于 ATR。
  • 默认值：
    • HmaPeriod = 9
    • AtrMultiplier = 2 ATR
    • CandleType = 15 分钟
  • 过滤条件：
    • 类别: 趋势跟随
    • 方向: 双向
    • 指标: Hull MA, ATR
    • 止损: 有
    • 复杂度: 基础
    • 时间框架: 日内
    • 季节性: 无
