高低点策略

基于最高价和最低价区间的策略。

当当前K线中点低于最高价和最低价平均值且归一化距离低于 LowThreshold 时买入。当中点高于平均值且归一化距离超过 HighThreshold 时平仓。

详情

  • 入场条件：中点低于平均值且归一化距离低于 LowThreshold。
  • 多/空：仅做多。
  • 出场条件：中点高于平均值且归一化距离高于 HighThreshold。
  • 止损：无。
  • 默认值：
    • Range = 100
    • LowThreshold = 15m
    • HighThreshold = 85m
    • CandleType = TimeSpan.FromMinutes(240)
  • 筛选器：
    • 类别：区间
    • 方向：做多
    • 指标：Highest, Lowest
    • 止损：无
    • 复杂度：基础
    • 时间框架：日内 (240m)
    • 季节性：无
    • 神经网络：无
    • 背离：无
    • 风险等级：中等
