求助老师如何更改公式指标

求老师帮忙改一下，意思：在附图上MACD柱状线大于前二根柱状线笑脸，MACD柱状线小于前二根柱状线哭脸。
谢谢。DIFF : EMA(CLOSE,12) - EMA(CLOSE,26);
DEA  : EMA(DIFF,9);
MACD : 2*(DIFF-DEA), COLORSTICK;
DRAWICON(CROSS(COUNT(CROSS(MACD>REF(MACD,2),0.5),BARSLAST(CROSS(MACD<REF(MACD,2),0.5))+1)=1,0.5),MACD,1),VALIGN0;
DRAWICON(CROSS(COUNT(CROSS(MACD<REF(MACD,2),0.5),BARSLAST(CROSS(MACD>REF(MACD,2),0.5))+1)=1,0.5),MACD,2);
DRAWICON(CROSS(DIFF,DEA),DIFF,4);
DRAWICON(CROSS(DEA,DIFF),DIFF,5);

博易技术人员： DIFF : EMA(CLOSE,12) - EMA(CLOSE,26);
DEA  : EMA(DIFF,9);
MACD : 2*(DIFF-DEA), COLORSTICK;

DRAWICON(CROSS(MACD>REF(MACD,1) AND MACD>REF(MACD,2),MACD<REF(MACD,1) AND MACD<REF(MACD,2)),MACD,1);
DRAWICON(CROSS(MACD<REF(MACD,1) AND MACD<REF(MACD,2),MACD>REF(MACD,1) AND MACD>REF(MACD,2)),MACD,2); 大多数线都是大于前两根或者小于前两根，MACD纯趋势型的图形。 来源 程序化久久网
