在MT4上使用双线MACD指标源码

MACD指标是股票交易中经典的一款技术分析指标，该指标由两条曲线和柱线组成。

基本用法：MACD金叉：DIFF由下向上突破DEA，为买入信号。MACD死叉：DIFF由上向下突破DEA，为卖出信号。MACD绿转红：MACD值由负变正，市场由空头转为多头。MACD红转绿：MACD值正转负，市场多头转空头。DIFF与DEA均为正值，即都在零轴线以上时，大势属于多头市场，DIFF向上突破DEA，可以做买入信号。DIFF与DEA均为负值，即都在零轴线以下时，大势属于空头市场，DIFF向下跌破DEA，可做卖出信号。DEA在盘整局面失误率高，配合RSI及KDJ指标可以适当弥补缺点。

效果如下：
