ICAi 策略

该策略基于自适应移动平均线 ICAi。指标根据标准差调整斜率并平滑价格。当指标向上转折时建立多头仓位，向下转折时建立空头仓位。

该算法可用于任何有K线数据的市场。默认设置使用4小时周期和12的平滑长度。

  • 入场条件:
    • 多头: Prev < PrevPrev && Current >= Prev
    • 空头: Prev > PrevPrev && Current <= Prev
  • 多空方向: 双向
  • 出场条件: 相反信号
  • 止损/止盈: 可选固定止损与止盈
  • 默认参数:
    • Length = 12
    • CandleType = TimeSpan.FromHours(4).TimeFrame()
    • TakeProfit = 2000
    • StopLoss = 1000
  • 过滤器:
    • 类别: 趋势跟随
    • 方向: 双向
    • 指标: ICAi
    • 止损: 支持
