Summary: 黄金联结EA是一款专为XAUUSD设计的MQL4智能交易系统。融合H4宏观趋势过滤、M15回调结构评分系统、RSI背离确认和ATR动态止损，适合H1周期分析配合M15入场。




黄金联结EA基于2024-2026年商业黄金EA的结构化原理设计。该EA融合了三个核心概念：H4宏观趋势过滤、M15回调结构专有评分系统、以及RSI背离确认。这种多时间框架融合方法确保交易与主导趋势一致，同时在最优回调区域入场。EA包含波动率自适应仓位管理、达到指定盈利阈值后激活的追踪止损系统、点差过滤和每日净值保护。不使用马丁格尔或网格回血——每笔交易独立，采用基于ATR的固定止损。

推荐加载周期： H1（主趋势分析）+ M15（入场时机）
策略核心逻辑：
  • 宏观趋势过滤：H4周期的EMA89和EMA34确定主趋势方向。EMA34必须在EMA89上方才能做多，或在下方才能做空。

  • 趋势强度验证：ATR标准化的EMA价差将趋势分为弱/正常/强——仅在正常或强趋势条件下允许交易。

  • M15回调检测：价格必须回撤至EMA20区域或RSI 45-55区间。

  • 入场触发：突破前一根K线的高低点且方向与趋势一致，同时需要RSI背离确认（价格极值与RSI极值的背离）。

  • 风险管理：ATR动态止损（1.6倍ATR），止盈2.8倍ATR，盈利达到1.2倍ATR后启动追踪止损。
