Stochastic Three Periods

Stochastic Three Periods 策略在三个时间框架上对齐随机指标信号。 当快速随机指标发生交叉且两个更高时间框架同向时开仓。

细节

  • 入场条件：快速 %K 向上/下穿越 %D，且在 ShiftEntrance 根K线前出现相反关系；两个更高时间框架的 %K 均在 %D 之上或之下；收盘价配合信号方向。
  • 多空方向：双向。
  • 出场条件：上一根K线的快速随机指标出现反向交叉。
  • 止损止盈：通过 StartProtection 以点数固定。
  • 默认值：
    • CandleType1 = 5m
    • CandleType2 = 15m
    • CandleType3 = 30m
    • KPeriod1 = 5
    • KPeriod2 = 5
    • KPeriod3 = 5
    • KExitPeriod = 5
    • ShiftEntrance = 3
    • TakeProfitPoints = 30
    • StopLossPoints = 10
  • 筛选：
    • 类型: 振荡指标
    • 方向: 双向
    • 指标: Stochastic
    • 止损: 是
    • 复杂度: 中等
    • 时间框架: 日内
    • 季节性: 否
    • 神经网络: 否
    • 背离: 否
    • 风险等级: 中等
