Summary: 黄金融合EA是一款专为XAUUSD设计的低风险MQL4智能交易系统。使用H4趋势过滤、H1入场信号和自适应ATR止损，适合黄金的高波动特性。建议加载H1图表。




黄金融合EA专为黄金（XAUUSD）设计，通过适应黄金的高波动和频繁反转特性，实现低风险、稳定收益。EA采用多周期方法：H4图表确定主趋势方向（EMA50），H1图表寻找回调入场信号（RSI背离+K线确认）。基于ATR的自适应止损和追踪止损在波动扩大时锁定利润。EA还包含点差保护、每日净值回撤限制和周五平仓功能，规避周末跳空风险。

推荐加载周期： H1（图表加载在H1，EA会自动读取H4数据）

策略核心逻辑：
  • 趋势过滤（H4）：H4周期EMA50定义多空方向。价格高于EMA只做多，低于EMA只做空。

  • 波动率状态（H1）：H1周期ATR(14)必须在20周期平均ATR的0.8~1.6倍区间内，超出则不开仓。

  • 入场信号（H1）：H1周期RSI(14)顶底背离 + 吞没K线形态确认。

  • 风险管理：固定止损250点或1.2倍H1 ATR（取较大值）。盈利350点后启动追踪止损，步长80点。每日亏损上限4%，最大点差35点。
