黄金信号脉冲EA - MQL4源码（XAUUSD多条件共振策略）

Summary: 黄金信号脉冲EA是一款专为XAUUSD设计的MQL4智能交易系统。结合EMA50趋势过滤、RSI(14)动量确认、ATR波动率保护和动态仓位管理，适合H1周期稳定运行。




黄金信号脉冲EA专为黄金（XAUUSD）设计，采用保守的多条件共振方法。与激进的网格或马丁格尔系统不同，本EA要求三个独立条件同时满足才会开仓：趋势方向（EMA50）、动量（RSI）和波动率状态（ATR）。EA仅在主趋势方向上进行交易，并避免在高波动期入场。动态仓位管理系统根据当前ATR水平调整手数，在黄金波动率飙升时降低风险敞口。额外的安全功能包括每日净值回撤保护、最大点差控制、周五平仓机制以及亏损交易后的冷却期。

推荐加载周期： H1
策略核心逻辑：
1. 趋势过滤：EMA(50)决定主要方向。价格高于EMA只做多；低于EMA只做空。
2. 动量确认：RSI(14)必须确认趋势（做多需要RSI>50，做空需要RSI<50）。
3. 入场信号：趋势确认后，等待价格回撤至EMA50区域并出现确认K线（收盘价沿趋势方向超越EMA）。
4. 波动率保护：当前ATR(14)不得超过30周期平均ATR的1.8倍。
5. 风险管理：基于1.5倍ATR的固定止损，3倍ATR止盈，盈利达到1倍ATR后启动追踪止损。
