# MACD金叉死叉EA带EMA趋势过滤 - 完整MQL4源码
本文提供一个基于MACD金叉死叉策略的完整自动交易EA，并加入趋势过滤增强功能。该策略因某热门交易视频声称回测胜率高达87%而在交易者中广泛传播。EA采用纪律化交易方式：只顺应大周期趋势方向开仓，通过MACD金叉死叉确认入场信号。
策略逻辑
EA使用200周期指数移动平均线(EMA)作为主趋势过滤器。当价格在EMA上方时，只考虑做多信号；当价格在EMA下方时，只考虑做空信号。MACD(12,26,9)通过快线与慢线的交叉产生入场信号，在零轴下方发生的金叉信号强度更高。EA还包含三级加仓机制，允许在每个方向上最多加仓三次，以改善平均入场价格。
