Summary: 黄金守护者EA是一款专为XAUUSD设计的MQL4智能交易系统。结合多时间框架EMA趋势过滤、ATR波动率保护、受控分层建仓和整体止盈机制，适合H4周期稳定运行。




黄金守护者EA专为黄金的长期稳定交易而设计，核心聚焦于资金保全。与激进的网格或马丁格尔系统不同，本EA采用纪律严明的趋势跟踪方法，配备多层安全机制。它等待H1和H4时间框架共同确认的高质量突破结构，然后以受控的分层系统入场，限制最大风险敞口。EA包含基于ATR的动态止损、波动率过滤、整体盈利保护以及每日净值防护。这种设计优先考虑一致性而非交易频率，适合追求账户稳步增长的交易者。

推荐加载周期： H4
策略核心逻辑：
  • 多时间框架确认：H4 EMA(200)定义宏观趋势；H1必须同向。

  • 突破检测：识别过去20根K线内形成的新的波段高低点。

  • 入场：在确认的结构水平之外布置挂单，需要ADX(14) > 25确认趋势强度。

  • 受控分层：最多追加2个仓位（合计3单），固定手数（无马丁格尔）。

  • 风险管理：ATR动态止损（1.5倍ATR），整体止盈机制，每日亏损上限5%。
