MaRsi Trigger 策略

该策略将快慢指数移动平均线（EMA）和 RSI 结合以识别趋势反转。 当快速 EMA 和 RSI 同时高于慢速指标时，认为市场看涨并开多头仓位。 当两者都低于慢速指标时，开空头仓位。参数可控制是否允许做多、做空及其平仓。

详情

  • 入场条件：
    • 多头：快速 EMA > 慢速 EMA 且快速 RSI > 慢速 RSI，并且上一趋势为看空。
    • 空头：快速 EMA < 慢速 EMA 且快速 RSI < 慢速 RSI，并且上一趋势为看多。
  • 出场条件：
    • 多头：趋势转为看空且允许平多。
    • 空头：趋势转为看多且允许平空。
  • 指标：EMA、RSI。
  • 止损：未包含。
  • 时间框架：默认使用4小时K线。
  • 参数：
    • FastRsiPeriod = 3
    • SlowRsiPeriod = 13
    • FastMaPeriod = 5
    • SlowMaPeriod = 10
    • AllowBuyEntry = true
    • AllowSellEntry = true
    • AllowLongExit = true
    • AllowShortExit = true
