MACD的精华就8个字：买小卖小，缩头缩脚。小指的是，红绿柱的堆而言，缩头缩脚是指红绿柱的长短而言。当股价一波比一波高时，反而红柱的堆，一堆比一堆小，证明产生了顶背离现象，应该及时卖出；当股价一波比一波低时，反而绿柱的堆一堆比一堆小，证明产生了底背离，应该买进。买点在绿堆小时，一根比一根短买进，也就是说缩脚时买进。当红堆小时，红柱一根比一根短时，叫缩头，卖出。
这里的"大"和"小"是指MACD中的大绿柱，小绿柱，和大红柱，小红柱。而在操作时图中的DIF和MACD两条白色和黄s的曲线，一般是视而不见的，我们只注重红绿柱的变化。
MACD指标中的柱状图分析
1、当红柱状持续放大时，表明股市处于牛市行情中，股价将继续上涨，这时应持股待涨或短线买入股票，直到红柱无法再放大时才考虑卖出。
2、当绿柱状持续放大时，表明股市处于熊市行情之中，股价将继续下跌，这时应持币观望或卖出股票，直到绿柱开始缩小时才可以考虑少量买入股票。
3、当红柱状开始缩小时，表明股市牛市即将结束（或要进入调整期），股价将大幅下跌，这时应卖出大部分股票而不能买入股票。
4、当绿柱状开始收缩时，表明股市的大跌行情即将结束，股价将止跌向上（或进入盘整），这时可以少量进行长期战略建仓而不要轻易卖出股票。
5、当红柱开始消失、绿柱开始放出时，这是股市转市信号之一，表明股市的上涨行情（或高位盘整行情）即将结束，股价将开始加速下跌，这时应开始卖出大部分股票而不能买入股票。
6、当绿柱开始消失、红柱开始放出时，这也是股市转市信号之一，表明股市的下跌行情（或低位盘整）已经结束，股价将开始加速上升，这时应开始加码买入股票或持股待涨。
