Safa Bot Alert 策略

Safa Bot Alert 策略利用短期 SMA 和 ADX 过滤器进行趋势交叉交易。价格上穿 SMA 且 ADX 高于阈值时做多，下穿且 ADX 高于阈值时做空。策略使用固定止盈、止损和跟踪止损，并在指定的会话时间平仓所有仓位。

细节

  • 入场条件：价格与 SMA 交叉且 ADX > AdxThreshold。
  • 多/空：双向。
  • 出场条件：止盈、止损、跟踪止损或会话收盘。
  • 止损：固定和跟踪。
  • 默认值：
    • SmaLength = 3
    • TakeProfitPoints = 80m
    • StopLossPoints = 35m
    • TrailPoints = 15m
    • AdxLength = 15
    • AdxThreshold = 15m
    • SessionCloseHour = 16
    • SessionCloseMinute = 0
    • CandleType = TimeSpan.FromMinutes(5)
  • 过滤器：
    • 分类：趋势跟随
    • 方向：双向
    • 指标：SMA, ADX
    • 止损：是
    • 复杂度：基础
    • 时间框架：日内
    • 季节性：无
    • 神经网络：否
    • 背离：否
    • 风险级别：中
