怎样用CCI指标在当下行情选出强势股？

JDEA:=EMA(JDIF,9);
Jmacd:=(JDIF-JDEA)*2;
JBOLL:=MA(CLOSE,20);
JUPPER:=JBOLL+2*STD(CLOSE,20);
JLOWER:=JBOLL-2*STD(CLOSE,20);
JK1:=CLOSE>OPEN ;
JK2:=VOL>=2*REF(VOL,1);
JK3:=CROSS(JDIF,JDEA) AND JDIF<=0 ;
JK4:=CROSS(CLOSE,JBOLL);
均线粘合:=JK1 AND JK2 AND JK3 AND JK4 ;
机构拉升:=机构加仓 AND 均线粘合;
DRAWTEXT (机构拉升,L*0.97,'↖机构拉升'),COLORFF00FF;
VARC:=SMA(MAX(C-REF(C,1),0),6,1)/SMA(ABS(C-REF(C,1)),6,1)*100;
DRAWICON(CROSS(82,VARC),H*1.02,2);
{DRAWTEXT(CROSS(82,VARC),2,'|逃庄'),COLORWHITE ;}
VAR34:=(INDEXC-REF(INDEXC, 1))/REF(INDEXC, 1);
VAR35:=(CLOSE-REF(CLOSE, 1))/REF(CLOSE, 1);
VAR36:=IF(VAR34>0.010, 0.900, 1) AND IF(VAR34>(-0.025), 1, 1.200);
VAR37:=VAR36*(VAR35-VAR34)*100;
