黄金曙光EA - MQL4源码（XAUUSD多策略自适应稳定系统）

Summary: 黄金曙光EA是一款专为XAUUSD设计的MQL4智能交易系统。结合波动率突破检测、ADX趋势强度过滤和动态仓位管理，适合H1周期稳定运行。




黄金曙光EA采用独特的混合策略架构，专为黄金稳定交易而设计。与单一策略系统不同，本EA监测三种不同的市场状态——盘整、趋势和突破——并相应调整交易逻辑。核心入场信号基于波动率收缩形态（布林带收窄）后的扩张突破，由ADX趋势方向确认。EA包含独立的风险管理模块，具备每日亏损限制、点差控制，以及独创的"市场记忆"功能，在连续亏损后自动暂停交易。

推荐加载周期： H1
策略核心逻辑：
1. 波动率状态检测：计算布林带(20,2)带宽。带宽过窄(<0.015)表示压缩期，过宽(>0.030)表示扩张期。
2. 突破确认：压缩期后，当价格以实体饱满的K线（实体/区间>0.7）收盘于布林带外时触发入场。
3. 趋势过滤：ADX(14) > 20时顺势交易；ADX < 20时使用均值回归逻辑（价格回归均线）。
4. 风险管理：固定止损1.8倍ATR(14)，止盈2.5倍ATR。盈利达到1倍ATR后启动追踪止损。
5. 市场记忆：连续亏损达到设定次数后暂停交易1小时。
