Summary: EURUSD三核EA是一款融合EMA趋势、随机震荡指标和K线形态三重确认的MQL4智能交易系统。专为欧美稳定低风险运行设计，适合H1周期。




EURUSD三核EA融合了三类互补逻辑：趋势跟踪（EMA）、动量/均值回归（随机指标）以及价格行为确认（K线形态）。EA仅当三个条件同时满足时才开仓，有效减少假信号。包含基于ATR的波动率过滤、每日亏损限制、点差控制和周五平仓保护。策略追求稳步复利增长，而非高频交易。

推荐加载周期： H1
策略核心逻辑：
  • 趋势过滤：EMA(50)判断方向（价格高于EMA只做多，低于EMA只做空）。

  • 随机指标过滤：做多要求Stochastic(14,3,3)低于20（超卖区）；做空要求高于80（超买区）。

  • K线确认：做多需要看涨吞没或锤子线；做空需要看跌吞没或射击之星。

  • 风险管理：固定止损250点，止盈450点。同时持仓最多1单，每日亏损上限5%，最大点差25点。
