请老师把以下公式中MACD在0轴上出现橙色柱体时改为选股指标，谢谢，辛苦了。
DIF:(EMA(C,5)-EMA(C,21))/EMA(C,21)*100,ColorF0F0F0;
DEA:EMA(DIF,8),COLOR00DCDC;
MACD:2*(DIF-DEA),COLOR0000DC,LINETHICK0;

X1:=BARSLAST(CROSS(0.5,COUNT(MACD>REF(MACD,1),X0+1)=X0+1));{回}

B4:=REF(B3,1) AND MACD>REF(MACD,1) AND C>O AND ZD>0;
DRAWTEXT(B4,ABS(MACD)+1.5,'◆'),COLORYELLOW,align1;
解答：
?DIF:=(EMA(C,5)-EMA(C,21))/EMA(C,21)*100;
DEA:=EMA(DIF,8);
