今日主力控盘系数小于昨日

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;

解答：

?zlcm:=ema(winner(c)*70,3);

shcm:=ema((winner(c*1.1)-winner(c*0.9))*80,3);
