ATR MACD 策略

该策略利用平均真实波幅(ATR)来调整仓位规模，并根据MACD的交叉进行交易。 ATR数值越大，持仓规模越小，从而在不同市场环境中保持风险一致。 当MACD与信号线交叉时入场，反向交叉或百分比止损触发退出。 这种组合旨在捕获动量的同时考虑到波动性的变化。

测试表明年均收益约为 154%，该策略在股票市场表现最佳。

细节

  • 入场条件：指标信号
  • 多/空：均可
  • 退出条件：止损或反向信号
  • 止损：是，按百分比
  • 默认值:
    • CandleType = 15分钟
    • StopLossPercent = 2
    • MacdFast = 12
    • MacdSlow = 26
    • MacdSignal = 9
    • AtrPeriod = 14
    • AtrAvgPeriod = 20 MACD上穿信号线做多、下穿做空，反向交叉反转持仓。每笔新仓位的数量为Volume乘以最近AtrAvgPeriod个ATR的平均值再除以当前ATR，并向下取整到成交量步长。
  • 过滤器:
    • 类别：趋势跟随
    • 方向：双向
    • 指标：ATR, MACD
    • 止损：有
    • 复杂度：中等
    • 时间框架：日内
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中等
