Terminator V2 策略

该策略使用移动平均收敛发散（MACD）指标进行双向交易。当 MACD 线向上穿越信号线时开多单；当 MACD 线向下穿越信号线时开空单。策略通过固定的止损和止盈保护持仓，并可选用追踪止损以在趋势行情中锁定利润。

细节

  • 入场条件：
    • 做多：MACD 上穿信号线。
    • 做空：MACD 下穿信号线。
  • 方向：双向。
  • 出场条件：
    • 触发止损或止盈。
    • 触发追踪止损。
  • 止损：支持止损、止盈和可选的追踪止损。
  • 默认参数：
    • FastPeriod = 14
    • SlowPeriod = 26
    • SignalPeriod = 1
    • TakeProfit = 500 点
    • StopLoss = 2500 点
  • 过滤器：
    • 类型：趋势跟随
    • 方向：双向
    • 指标：MACD
    • 止损：是
    • 复杂度：中等
    • 时间框架：短期
