发一个自用的通达信MACD指标吧。无未来，也不是完全原创。
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s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，
将MACD设置为三个步骤来操作:
买入法则:
1)当.MACD绿柱由长缩短时可以考虑买1/3;
2).当DIFF由下降转平或调头向上时再买1/3;
3).当DIFF由下向上上穿DEA(即金叉)时就可以全仓买进了（也就是剩下1/3买进）;
当股票上升到一定的幅度时,卖出法则:
4).当MACD柱由长红开始缩短时,可以考虑卖出1/3;
5)当DIFF由上升开始走平或向下时,再卖出1/3;
6).当DIFF下穿DEA(即死叉)时,就将剩下的1/3全仓卖出!}
