老师麻烦你给改一下MACD指标 (文华财经WH6赢顺V6.7)

要求MACD叠加在主图上、要求MACD的红柱和绿主变色成和K线不同的两种颜色。

DIFF :=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA  := EMA(DIFF,9);
MACD:2*(DIFF-DEA),COLORSTICK;
MA20:=MA(C,20),COLORRED;

 MACD指标柱体变色参考：

DIFF :=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA  := EMA(DIFF,9);
MACD:=2*(DIFF-DEA),COLORSTICK;

DRAWLINE(MACD>0,0,MACD>0,MACD,0),COLORYELLOW;
DRAWLINE(MACD<0,0,MACD<0,MACD,0),COLORGREEN;
