黄金信号专业EA - MQL4源码（XAUUSD七层过滤系统）

Summary: 黄金信号专业EA是一款专为XAUUSD设计的MQL4智能交易系统，整合7层独立过滤器包括多时间框架趋势确认、RSI动量、波动率检测和MA结构分析，适合M15稳定运行。




黄金信号专业EA专为XAUUSD构建，采用严格的七层过滤系统剔除低概率信号。与典型的网格或马丁格尔EA不同，本策略通过多时间框架确认（M5入场、H1趋势、H4主方向）、波动率状态检测和动态质量评分来优先保证信号质量。每个信号都带有基于当前ATR和市场结构计算的TP/SL水平。EA包含每日净值保护、点差监控、时段过滤和周五平仓机制。

推荐加载周期： M15
策略核心逻辑：
1. 多时间框架过滤：H4 EMA(50)决定主趋势方向，H1确认中期方向，M5扫描入场触发。
2. 波动率检测：当前ATR不得超过20周期平均ATR的1.6倍，异常波动峰值阻止交易。
3. MA结构检查：验证SMA 13/21/75/100的排列顺序，均线走平期间自动过滤。
4. RSI动量过滤：做多信号要求RSI(14)>50，做空信号要求RSI(14)<50，避免超买超卖极端入场。
5. 质量评分系统：每个信号基于多重共振因素评分（★★★强信号，★★标准信号，★谨慎信号）。
6. 风险管理：基于ATR的动态止损（1.4倍ATR），止盈（2.5倍ATR）。盈利达到1倍ATR后启动追踪止损。
