Cycle Biologique策略

Cycle Biologique策略基于正弦周期。当周期上穿零轴时做多，周期下穿零轴时平仓。

细节

  • 入场条件：周期上穿零轴。
  • 出场条件：周期下穿零轴。
  • 默认参数：
    • CycleLength = 30
    • Amplitude = 1.0
    • Offset = 0
  • 过滤器：
    • 类型：Cycle
    • 方向：多头
    • 指标：正弦波
    • 止损：否
    • 复杂度：低
    • 时间框架：任意
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中等
