AI Supertrend Pivot Percentile 策略

该策略结合两个 Supertrend 指标、ADX 过滤器以及 Williams %R 枢轴百分位过滤。 当价格位于两个 Supertrend 之上、ADX 显示强趋势且 Williams %R 高于 -50 时开多仓；相反条件下开空仓。

详情

  • 入场条件:
    • 多头: 价格高于两个 Supertrend，ADX 大于阈值，Williams %R > -50。
    • 空头: 价格低于两个 Supertrend，ADX 大于阈值，Williams %R < -50。
  • 多/空: 双向。
  • 离场条件:
    • 反向信号。
  • 止损: 基于百分比的止盈和止损。
  • 默认参数:
    • Length1 = 10
    • Factor1 = 3
    • Length2 = 20
    • Factor2 = 4
    • AdxLength = 14
    • AdxThreshold = 20
    • PivotLength = 14
    • TpPercent = 2
    • SlPercent = 1
  • 过滤器:
    • 类别: 趋势跟随
    • 方向: 双向
    • 指标: SuperTrend, ADX, Williams %R
    • 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
