MACD配合1日随机指标确认的反转策略

当MACD线向上穿越信号线并且日线随机指标K线高于D线且低于80时买入。价格跌破ATR计算的止损或跌破追踪EMA止盈线时平仓。

细节

  • 入场条件：
    • 多头：MACD上穿Signal 且 DailyK > DailyD 且 DailyK < 80
  • 多空方向：仅做多
  • 止损：ATR止损和EMA追踪止盈
  • 默认参数：
    • MacdFastLength = 12
    • MacdSlowLength = 26
    • MacdSignalLength = 9
    • TrailingEmaLength = 20
    • StopLossAtrMultiplier = 3.25m
    • TrailingActivationAtrMultiplier = 4.25m
    • CandleType = TimeSpan.FromHours(1).TimeFrame()
  • 过滤器：
    • 类别：反转
    • 方向：多头
    • 指标：MACD, Stochastic, ATR, EMA
    • 止损：是
    • 复杂度：中等
    • 时间框架：中期
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中等
