Higher Order Pivots 策略

使用 3 根或 5 根 K 线定义的枢轴点来检测一、二、三阶高低点。该策略仅用于分析，不会下单。

详情

  • 入场条件：
    • 无（仅分析）。
  • 出场条件：
    • 无。
  • 指标：
    • 3 或 5 根 K 线的枢轴点检测。
  • 止损：无。
  • 默认值：
    • CandleType = 5m
    • UseThreeBar = true
    • DisplayFirstOrder = true
    • DisplaySecondOrder = true
    • DisplayThirdOrder = true
  • 过滤器：
    • 单一时间框
    • 指标：枢轴检测
    • 止损：无
    • 复杂度：低
