黄金结构边缘EA - MQL4源码（XAUUSD枢轴突破策略）

Summary: 黄金结构边缘EA是一款专为XAUUSD设计的MQL4智能交易系统，识别H1枢轴区突破并由多EMA趋势过滤确认。包含硬性回撤限制、每日亏损上限和纯结构逻辑。




黄金结构边缘EA基于一个核心理念设计：成功的黄金交易需要结构清晰而非信号噪音。EA识别H1枢轴区——定义市场结构的波段高点和低点——并等待价格突破这些水平，同时接受多EMA趋势过滤器（维加斯隧道：144、288、576 EMA）的确认。不使用马丁格尔、网格或对冲。每笔交易都带有设在枢轴区之外的硬止损，以及基于ATR风险回报比的止盈。EA包含真正生效的硬编码风控限制：每日亏损上限停止交易、总回撤保护阻止新开仓、紧急制动在波动率超过2.5倍ATR时平仓所有头寸。这些限制并非装饰——它们是策略在整个市场周期中保持可控回撤的原因。

推荐加载周期： H1
策略核心逻辑：
1. 枢轴区检测：识别最近20根H1 K线的最高高点和最低低点作为结构枢轴水平。
2. 趋势过滤：维加斯隧道（EMA 144、288、576）在H1上必须全部同向排列。
3. 突破确认：价格收盘高于枢轴高点（做多）或低于枢轴低点（做空），且为动量K线（实体 > 0.7倍区间）。
4. 入场：确认后下一根K线开盘价入场。
5. 风险管理：硬止损为枢轴区外1.5倍ATR；止盈为2.2倍ATR；盈利达到0.8倍ATR后启动追踪止损。
