把成交量公式做个选股公式

VOLUME:VOL,VOLSTICK;
AA:=VOL>REF(V,1)*1.9;
AA1:=VOL<REF(LLV(VOL,13),1);
AA2:=VOL<REF(LLV(VOL,55),1);
STICKLINE(AA,0,V,1,0),COLORYELLOW;
STICKLINE(AA1,0,V,1,0),COLORGREEN,LINETHICK1;
STICKLINE(AA2,0,V,1,0),COLORMAGENTA;
TJ1:=COUNT(V>REF(V,1)*1.9,4)=1;
TJ2:=COUNT(V<REF(V,1) AND L>MIN(L,4) AND L>REF(L,1),3)=3 ;
TJ3:=TJ1 AND TJ2;
STICKLINE(TJ3,0,V,1,0),COLORRED;
MV2:MA(V,2),color00ff00 ;
MV6:MA(V,6),COLORCYAN
;
MV20:MA(V,20),COLORRED ;

请老师做个图中画圈的，缩量两天中间有一天放量的选股公式，也就是今天缩量昨天是量大些，前天是缩量的。出现这种图形的选股公式，

ref(v/ref(v,1)>=1.9 and c>o,1) and v/ref(v,1)<=0.6;
