黄金动量流EA - MQL4源码（XAUUSD趋势跟踪）

Summary: 黄金动量流EA是一款专为XAUUSD设计的MQL4智能交易系统。使用双EMA交叉配合RSI动量确认和ATR动态止损，适合H1周期稳定运行。




黄金动量流EA专门为黄金（XAUUSD）设计，捕捉中期趋势运动，同时管理黄金特有的波动率飙升。该EA结合双EMA交叉（快EMA12，慢EMA26）判断趋势方向，RSI(14)动量过滤器避免低动量假突破，以及基于ATR的动态止损，在高波动时自动放宽止损。每笔交易包含追踪止损，随着趋势发展锁定利润。

推荐加载周期： H1
策略核心逻辑：
1. 趋势检测：快EMA12上穿慢EMA26为上涨趋势；反之下跌趋势。
2. 动量过滤：做多要求RSI(14)>50，做空要求RSI(14)<50。
3. 入场确认：等待交叉后K线收盘，同时动量条件成立。
4. 风险管理：动态止损为1.5倍ATR，止盈为3倍ATR，盈利达到1倍ATR后启动追踪止损。
