GoldStabilityPro EA - MQL4源码（XAUUSD稳定趋势策略 ADX+ATR）

Summary: GoldStabilityPro EA是一款专为XAUUSD设计的MQL4智能交易系统。将ADX趋势过滤与基于ATR的动态止损相结合，适合H1周期长期稳定运行。




GoldStabilityPro EA专门为XAUUSD设计，专注于长期稳定性和资金保全。与激进的高频系统不同，本EA将交易质量置于数量之上，仅在趋势强度和波动率条件同时满足时执行交易。策略结合ADX进行趋势过滤，ATR进行动态仓位管理。每笔交易都基于当前市场波动率设有固定止损和止盈，确保风险可控。EA包含每日净值保护、点差控制和周五平仓机制。

推荐加载周期： H1
策略核心逻辑：
1. 趋势强度过滤：ADX(14)必须高于ADX最小阈值（默认25），确保处于趋势市场。
2. 方向过滤：DI+（看涨）或DI-（看跌）决定交易方向，选择占优的一方。
3. 波动率评估：计算ATR(14)并用于动态止损设置。
4. 入场确认：价格必须收盘于H1 EMA(50)之外，且方向与占优DI一致。
5. 风险管理：固定止损（默认300点）和止盈（默认600点），可选ATR缩放功能。
