AI Volume策略

AI Volume策略寻找成交量的突然放大。当当前成交量超过其EMA乘以设定的倍数，价格位于50期EMA之上/下并且K线颜色一致时，在该方向开仓。每笔交易在固定数量的K线后平仓。

细节

  • 入场条件：成交量 > VolumeEMA × VolumeMultiplier 且价格与K线颜色相符地位于50 EMA之上/下。
  • 方向：双向。
  • 出场条件：在 ExitBars 根K线后平仓。
  • 止损：无。
  • 默认参数：
    • VolumeEmaLength = 20
    • VolumeMultiplier = 2.0
    • ExitBars = 5
    • CandleType = TimeSpan.FromMinutes(1)
  • 过滤器：
    • 类型：成交量突破
    • 方向：双向
    • 指标：EMA、Volume EMA
    • 止损：无
    • 复杂度：基础
    • 时间框架：任意
    • 季节性：无
    • 神经网络：无
    • 背离：无
    • 风险等级：中等
