Zig Zag Aroon Strategy

该策略将简单的 ZigZag 枢轴识别与 Aroon 指标结合。当 Aroon Up 上穿 Aroon Down 且最近的枢轴为高点时买入。Aroon Down 上穿 Aroon Up 且最新枢轴为低点时做空。

细节

  • 入场条件：Aroon 交叉并匹配 ZigZag 枢轴。
  • 多空方向：双向。
  • 出场条件：反向信号。
  • 止损：无。
  • 默认值:
    • ZigZagDepth = 5
    • AroonLength = 14
    • CandleType = TimeSpan.FromMinutes(1)
  • 过滤器:
    • 类别: 趋势
    • 方向: 双向
    • 指标: Aroon, ZigZag
    • 止损: 无
    • 复杂度: 基础
    • 时间框架: 日内
    • 季节性: 无
    • 神经网络: 无
    • 背离: 无
    • 风险水平: 中等
