MA Crossover Demand Supply Zones SLTP 策略

该策略将长短期简单移动平均线交叉与需求/供应区结合。当交叉发生在最近确认的需求区或供应区附近时入场，并以固定百分比的止损和止盈管理仓位。

细节

  • 入场条件：
    • 多头：短期SMA在需求区附近上穿长期SMA。
    • 空头：短期SMA在供应区附近下穿长期SMA。
  • 方向：双向。
  • 出场条件：
    • 价格触及止盈或止损。
  • 止损：按百分比的止损和止盈。
  • 默认值：
    • ShortMaLength = 9
    • LongMaLength = 21
    • ZoneLookback = 50
    • ZoneStrength = 2
    • StopLossPercent = 1
    • TakeProfitPercent = 2
  • 过滤器：
    • 类别：趋势跟随
    • 方向：双向
    • 指标：SMA, Highest, Lowest
    • 止损：是
    • 复杂度：基础
    • 时间框架：任意
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中
