Golden Ratio Cubes策略

Golden Ratio Cubes策略利用斐波那契数计算金分率扩展。策略追踪一段时间内的最高价和最低价，并基于黄金分割(φ ≈ 1.618)计算突破水平。当价格收盘突破这些水平时，按照突破方向入场。

细节

  • 入场条件：
    • 收盘价高于黄金分割扩展水平 → 买入。
    • 收盘价低于黄金分割扩展水平 → 卖出。
  • 方向：多头和空头。
  • 出场条件：
    • 相反方向的突破信号。
  • 止损：无。
  • 默认参数：
    • Lookback = 34
    • Phi = 1.618
  • 过滤器：
    • 类型：突破
    • 方向：多头和空头
    • 指标：Highest, Lowest
    • 止损：无
    • 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
