通达信的虚拟成交量在选股公式中该怎么表达？

虚拟量:=IF(DYNAINFO(7)=CLOSE AND DYNAINFO(10)=AMOUNT,MAX(VOL,DYNAINFO(17)*REF(MA(VOL,5),1)),0);
STICKLINE(DYNAINFO(7)=CLOSE AND DYNAINFO(10)=AMOUNT,VOL,MAX(VOL,DYNAINFO(17)*REF(MA(VOL,5),1)),4,-21),COLOR00C0C0;
VOLUME:VOL,VOLSTICK;
VOLL:IF(虚拟量>0,虚拟量,VOLUME);
??
上面是指标源码
选股公式里：
虚拟量1:=IF(DYNAINFO(7)=CLOSE AND DYNAINFO(10)=AMOUNT,MAX(VOL,DYNAINFO(17)*REF(MA(VOL,5),1)),0);
VOLUME:=VOL;
虚拟量:IF(虚拟量>0,虚拟量1,VOLUME);
