动量突破策略

该系统寻找动量相对其历史平均值的突然增加。当动量读数大幅高于平均水平时，价格可能开始快速单边运行。

测试表明年均收益约为 82%，该策略在股票市场表现最佳。

动量高于均值加 Multiplier 倍标准差时买入；低于均值减同倍数时做空。动量回到均值附近便平仓。

此策略适合喜好追逐快速行情的交易者，止损按价格百分比设置以防突破失败。

详细信息

  • 入场条件:
    • 做多: 动量 > Avg + Multiplier * StdDev
    • 做空: 动量 < Avg - Multiplier * StdDev
  • 多空方向: 双向
  • 退出条件:
    • 做多: Exit when 动量 < Avg
    • 做空: Exit when 动量 > Avg
  • 止损: 是
  • 默认值:
    • 动量Period = 14
    • AveragePeriod = 20
    • Multiplier = 2.0m
    • CandleType = TimeSpan.FromMinutes(5)
  • 筛选条件:
    • 类别: 突破
    • 方向: 双向
    • 指标: 动量
    • 止损: 是
    • 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
