其实MACD的精华就8个字：买小卖小，缩头缩脚。一个单独的MACD并不能说明多大问题，但各种优化的的指标结合共振就有一定意义了。
各种背离信号和文字颜色是一致的。空心柱为背离信号。MACD二次金叉会文字提示
{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两条白色和黄色的曲线，
一般是视而不见的，我们只注重红绿柱的变化。}
{在牛市行情里，该指标准确率更高！我对MACD的理解是,当股票下跌时，
