Polynomial Regression Bands Channel 策略

该策略对最近价格进行多项式回归，并根据残差的标准差构建上下通道。当价格跌破下轨时开多头仓位，当价格突破上轨时开空头仓位。

细节

  • 入场条件:
    • 多头: Close < LowerBand。
    • 空头: Close > UpperBand。
  • 多空方向: 双向。
  • 出场条件:
    • 相反信号。
  • 止损: 否。
  • 默认值:
    • Length = 100。
    • Degree = 2。
    • Std Dev Multiplier = 2。
  • 筛选器:
    • 类别: 均值回归
    • 方向: 双向
    • 指标: 多项式回归
    • 止损: 否
    • 复杂度: 中等
    • 时间框架: 中期
    • 季节性: 否
    • 神经网络: 否
    • 背离: 否
    • 风险等级: 中等
