求助老師如何更改公式指標

求老師幫忙改一下，意思：在附圖上MACD柱狀線大于前二根柱狀線笑臉，MACD柱狀線小于前二根柱狀線哭臉。
謝謝。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);

博易技術人員： 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); 大多數線都是大于前兩根或者小于前兩根，MACD純趨勢型的圖形。 來源 程序化久久網
