請老師幫我加個大于0和小于0的箭頭

 DIFF :EMA(CLOSE,8) - EMA(CLOSE,21);
DEA  : EMA(DIFF,13),NODRAW;
MACD:2*(DIFF-DEA),COLORSTICK;
DRAWCOLORLINE(DEA>REF(DEA,1),DEA,COLORRED,COLORGREEN),LINETHICK3;
STICKLINE(MACD>0&&MACD>REF(MACD,1),MACD,0,COLORRED,0);
STICKLINE(MACD>0&&MACD<REF(MACD,1),MACD,0,COLORYELLOW,0);
STICKLINE(MACD<0&&MACD>REF(MACD,1),MACD,0,COLORGREEN,0);
STICKLINE(MACD<0&&MACD<REF(MACD,1),MACD,0,COLORBLUE,0);

DIFF大于0用紅箭頭表示，小于0用綠箭頭表示，謝謝！

DRAWICON(DIFF>0,DIFF,'ICO4');

DRAWICON(DIFF<0,DIFF,'ICO5');
