黄金波动守护者EA - MQL4源码（XAUUSD多层保护系统）

Summary: 黄金波动守护者EA是一款专为XAUUSD设计的MQL4智能交易系统。使用MACD趋势过滤、多层仓位进阶（最多3层）和基于ATR的动态风控，适合H4周期稳定运行。




黄金波动守护者EA专为黄金（XAUUSD）设计，核心聚焦于资金保全。与激进的网格系统不同，本EA采用纪律严明的趋势跟踪方法，使用MACD(12,26,9)确认趋势方向，并结合EMA交叉验证。EA采用多层仓位系统，每一层新增仓位必须满足更严格的入场条件。基于权益的追踪止损在保护利润的同时允许趋势延续。EA包含每日亏损限额、点差过滤和周五平仓机制。

推荐加载周期： H4
策略核心逻辑：
1. 趋势检测：MACD主线高于信号线为上涨趋势；低于则为下跌趋势。EMA(20)与EMA(50)交叉提供额外确认。
2. 入场信号：价格回撤至EMA(50)并在趋势方向收盘超越该线，同时MACD动量确认。
3. 多层进阶：仅当现有持仓盈利达到1.5倍ATR时才允许加仓（最多3层）。
4. 风险管理：ATR动态止损、基于权益的追踪止损、每日亏损上限5%。
