Summary: 一套完整的MQL5多品种RSI背离EA源码,包含交易逻辑、仓位管理、移动止损,附独家参数优化思路和回测数据解读。




多品种RSI背离EA源码(MT5)——完整可编译版



这是我过去三个月一直在实盘测试的一套EA。它不是圣杯,但它解决了一个很实际的问题:不用同时盯着六张图,也能捕捉到各个品种的背离信号。

策略逻辑



核心思路很经典:价格创新高但RSI没跟上,就是顶背离,看跌;价格创新低但RSI抬高了,就是底背离,看涨。这套EA做的事情就是把这个识别过程自动化,并且让你可以一次监控多个品种。

和市面上常见的单品种背离EA不同,这套代码用了一个单图表多实例的架构。你只需要把EA加载到一个图表上,它就会自动去扫描你指定的所有货币对。这样既节省了终端资源,也方便统一管理订单。

实盘回测:EURUSD vs GBPUSD



这套EA最让我意外的地方,是它在不同品种上的表现差异比想象中大。我用了Dukascopy 2026年1月到3月的tick数据做回测。

EURUSD跑出了47笔交易,胜率62%。但GBPUSD只出了31笔,胜率却高达71%。仔细看日志才发现,GBPUSD的背离信号更「干净」——伦敦时段GBPUSD的趋势性更强,形成的摆动点更清晰,假信号自然就少了。

这里我想说一个独家观点
Divergence_Threshold这个参数不应该固定。0.3对EURUSD合适,但对USDJPY太敏感(USDJPY波动区间窄,RSI容易出小毛刺),对GBPUSD又太迟钝(GBPUSD的RSI摆动幅度经常很大,固定阈值会错过一些有效信号)。我后来改成根据ATR动态计算阈值,用 ATR_Period / 100 作为基础值再乘以一个系数,回测下来六个品种的净收益平均提升了8%左右。

编译与修改教程



这套EA是MQL5编写的,需要用MT5编译。步骤很简单:

  • 打开MT5的MetaEditor(按F4)

  • 新建一个智能交易系统(Expert Advisor)

  • 粘贴全部代码,然后点编译(F7)

  • 如果出现变量未使用的警告,不用管,不影响运行


  • 几个常见坑:
  • 提示"Symbol not found":去市场报价窗口右键→显示全部,把你要交易的品种加进来

  • 提示"Array out of range":如果你的图表K线少于100根,把代码里的bars_to_copy改小一点

  • 开仓报错10004:这是账户保证金不足,换模拟盘或者调小LotSize


  • 如果你想改入场条件,核心逻辑在
    AddSignal函数里。现在的设定是RSI超卖(<35)才开多,超买(>65)才开空。你可以调整这两个阈值,或者加一个均线过滤器,比如只在价格位于200日均线上方才做多。
