【MACD多周期】指标

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;

DEA:EMA(DIF,9),COLOR1AFFFF,NODRAW;
