IU Bigger Than Range 策略

当当前K线实体大于之前区间时入场的突破策略。

系统比较当前K线实体与设定周期内开收价的最高和最低范围。如果实体超过前一范围，则按K线方向开仓，并根据所选方法设置止损和止盈。

细节

  • 入场条件：K线实体大于前一范围；方向取决于K线实体。
  • 多空方向：双向。
  • 出场条件：止损或止盈触发。
  • 止损：前一K线、ATR或摆动高/低。
  • 默认值：
    • LookbackPeriod = 22
    • RiskToReward = 3
    • StopLossMethod = PreviousHighLow
    • AtrLength = 14
    • AtrFactor = 2m
    • SwingLength = 10
    • CandleType = TimeSpan.FromMinutes(1)
  • 过滤器：
    • 类别：突破
    • 方向：双向
    • 指标：Highest, Lowest, ATR
    • 止损：是
    • 复杂度：中等
    • 时间框架：任意
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中等
