编写要求：

DIF:EMA(CLOSE,12)-EMA(CLOSE,26),COLORFF00FF,NODRAW;DEA:EMA(DIF,9),COLOR1AFFFF,NODRAW;MACD:(DIF-DEA)*2,COLOR0000F2,NODRAW;STICKLINE("MACD.MACD#WEEK">=0,0,"MACD.MACD#WEEK",4,0),COLOR000055;STICKLINE("MACD.MACD#WEEK"<0,0,"MACD.MACD#WEEK",4,0),COLOR515100;STICKLINE(MACD>=0 AND MACD>=REF(MACD,1),0,MACD,1,0),COLOR0000F2;STICKLINE(MACD>=0 AND MACD=REF(MACD,1),0,MACD,1,1),COLOR008000;ES:=REF(EMA(C,26),1);EP:=REF(EMA(C,12),1);DI:=REF(DIF,1);DIF穿零价:((12+1)*(26-1)*ES-(26+1)*(12-1)*EP)/(2*(26+1)-2*(12+1)),NODRAW,COLORWHITE;DIF拐点价:((12-1)*EP/(12+1)-(26-1)*ES/(26+1)-DI)*(26+1)*(12+1)/(2*(12+1)-2*(26+1)),COLORYELLOW,NODRAW;IF(1,DIF,DRAWNULL),COLORCYAN;IF(DIF>=REF(DIF,1),DIF,DRAWNULL),COLORFF00FF;IF(1,DEA,DRAWNULL),COLOR1AFFFF;

解答：

 DIF:EMA(CLOSE,12)-EMA(CLOSE,26),COLORFF00FF,NODRAW;
