Keltner Macd Strategy

本策略结合Keltner通道和MACD指标。当价格突破上轨且MACD在信号线上方时做多；跌破下轨且MACD在信号线下方时做空。MACD与信号线出现反向交叉时离场。

测试表明年均收益约为 169%，该策略在加密市场表现最佳。

Keltner通道提供突破信号，MACD动量用于过滤方向。适合寻求波动扩张并依靠动量确认的交易者，止损基于ATR倍数。

细节

  • 入场条件:
    • 多头: Close > UpperBand && MACD > Signal
    • 空头: Close < LowerBand && MACD < Signal
  • 多/空: 双向
  • 离场条件: MACD反向交叉
  • 止损: ATR倍数，使用 AtrMultiplier
  • 默认值:
    • EmaPeriod = 20
    • Multiplier = 2m
    • AtrPeriod = 14
    • MacdFastPeriod = 12
    • MacdSlowPeriod = 26
    • MacdSignalPeriod = 9
    • AtrMultiplier = 2m
    • CandleType = TimeSpan.FromMinutes(15).TimeFrame()
  • 过滤器:
    • 类别: Mean reversion
    • 方向: 双向
    • 指标: Keltner Channel, MACD
    • 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
