编写要求：

主力控盘系数指标，请老师帮忙编写一个“今日主力控盘系数小于昨日主力控盘系数”的选股公式，多谢了ZLCM:=EMA(WINNER(CLOSE)*70,3);SHCM:=EMA((WINNER(CLOSE*1.1)-WINNER(CLOSE*0.9))*80,3);ZSHTL:=SHCM/(ZLCM+SHCM)*100;ZZLKP:=ZLCM/(ZLCM+SHCM)*100;ZCMZL:=MA(ZLCM+SHCM,13);ZSHJJ:=EMA(ZSHTL,89);ZZLJJ:=EMA(ZZLKP,89);ZJLRQD:=(ZZLKP-ZZLJJ);SH8:=EMA(ZSHTL,8);DKB:=IF(ZZLKP-REF(ZZLKP,1)>ZSHTL-REF(ZSHTL,1),1,0);主力控盘系数:(ZZLKP),LINETHICK1,COLORRED;50,DASHLINE,COLORYELLOW;DRAWTEXTABS(0,175,'系数50%');主力控盘连红:LAST(ZZLKP>REF(ZZLKP,1)),COLORBLUE;STICKLINE(ZZLKP<50,ZZLKP,0,7,0),COLORBLUE;STICKLINE(ZZLKP>=50 AND ZZLKP<75,50,0,7,0),COLORBLUE;STICKLINE(ZZLKP>=50 AND ZZLKP<75,50,ZZLKP,7,0),COLORYELLOW;STICKLINE(ZZLKP>=75,50,0,7,0),COLORBLUE;STICKLINE(ZZLKP>=75,50,75,7,0),COLORYELLOW;STICKLINE(ZZLKP>=75,75,ZZLKP,7,0),COLORRED;IF(ZZLKP>REF(ZZLKP,1),ZZLKP+5,0),CIRCLEDOT,COLORRED;
