Up3x1 策略

Up3x1 策略使用三条简单移动平均线来捕捉趋势变化：

  • 快速 SMA：快速响应价格变化。
  • 中速 SMA：提供趋势的额外确认。
  • 慢速 SMA：定义市场的总体方向。

入场规则

  • 当快速 SMA 向上穿越中速 SMA 且两者都位于慢速 SMA 下方时买入。
  • 当快速 SMA 向下穿越中速 SMA 且两者都位于慢速 SMA 上方时卖出。

出场规则

  • 每笔交易设置固定的止盈和止损。
  • 可选的追踪止损在入场后跟随价格以保护利润。

参数

  • Volume – 委托量。
  • TakeProfit – 以价格单位表示的止盈值。
  • StopLoss – 以价格单位表示的止损值。
  • TrailingStop – 追踪止损距离，设为 0 表示禁用。
  • FastPeriod、MiddlePeriod、SlowPeriod – 移动平均线周期。
  • CandleType – 计算所用的蜡烛图时间框架。

该策略用于演示，可根据具体交易工具或条件进一步定制。
