黄金地平线EA - MQL4源码（XAUUSD稳健趋势跟踪策略）

Summary: 黄金地平线EA是一款专为XAUUSD设计的MQL4智能交易系统。使用多时间框架EMA趋势确认、ATR动态止损和每日亏损限额，适合H1周期稳定运行。




黄金地平线EA专门为黄金（XAUUSD）设计，通过聚焦趋势方向和波动率感知实现稳定、低风险的运营。与激进的网格或马丁格尔系统不同，本EA将信号质量置于交易频率之上。它使用多时间框架趋势确认（H1和H4 EMA）确保与更广泛的市场方向一致。基于ATR的波动率过滤器防止在市场噪音过大时入场，而动态ATR止损则适应黄金当前的波动特性。EA包含每日净值保护、点差控制和周五平仓机制，以规避周末缺口风险。

推荐加载周期： H1
策略核心逻辑：
1. 多时间框架趋势：H4 EMA(50)决定主要趋势方向，H1必须同向交易。
2. 动量过滤：RSI(14)必须确认动量（做多>50，做空<50）。
3. 入场触发：价格回撤至H1 EMA(20)并收盘超越该线，方向与趋势一致。
4. 波动率保护：当前ATR(14)不得超过20周期平均ATR的1.8倍。
5. 风险管理：动态止损为1.5倍ATR，止盈为3倍ATR。盈利达到1倍ATR后启动追踪止损。
