Color Zero Lag MA 策略

该策略使用零滞后移动平均线（Zero Lag Moving Average）来捕捉趋势反转。当 ZLMA 曲线从下降转为上升时开多仓，从上升转为下降时开空仓。若指标斜率反向，则平掉当前仓位。

参数

  • Length：零滞后均线的周期。
  • Candle Type：策略使用的 K 线周期。
  • Open Buy：允许开多仓。
  • Open Sell：允许开空仓。
  • Close Buy：当 ZLMA 向下转折时平多仓。
  • Close Sell：当 ZLMA 向上转折时平空仓。

逻辑

  1. 订阅指定周期的 K 线。
  2. 计算零滞后移动平均值。
  3. 跟踪最近两次 ZLMA 的数值以判断斜率方向。
  4. 斜率从下行转为上行时，平空并开多。
  5. 斜率从上行转为下行时，平多并开空。

该方法利用指标颜色的变化来捕捉可能的趋势反转。
