根据一个成交量公式帮忙编个通达信副图指标及其选股公式

VVOL:IF(CURRBARSCOUNT=1 AND PERIOD=5,VOL*240/FROMOPEN,DRAWNULL),NODRAW;
STICKLINE(CURRBARSCOUNT=1 AND PERIOD=5,VVOL,0,-1,-1),COLOR00C0C0;
VOLUME:VOL,VOLSTICK;
AA:=VOL>=REF(V,1)*1.91 && C>REF(C,1);
AA1:=VOL<REF(LLV(VOL,21),1);
AA2:=VOL<REF(LLV(VOL,55),1);
AA3:=ABS(VOL-REF(VOL,1))/REF(VOL,1)<=0.05;
STICKLINE(AA,0,V,1,0),COLORYELLOW;
STICKLINE(AA1,0,V,1,0),COLORGREEN;
STICKLINE(AA2,0,V,1,0),COLORMAGENTA;
STICKLINE(AA3,0,V,1,0),COLORWHITE;
MV1:MA(VOL,5);
MV2:MA(VOL,10);
MV3:MA(VOL,20);
这个公式中成交量显示为黄色时以及kdj（参数用系统默认的9，3，3即可）指标中的J值小于等于70的时候显示一个向上的红色箭头代表买入。根据所编写的公式请另外编写选股公式，谢谢！
成交量显示黄色 and J值小于等于70 同时成立的时候在指标中标示出向上的红色箭头代表买入

标示出向上的红色箭头

选股:KDJ.J<=70 AND VOL>=REF(V,1)*1.91 && C>REF(C,1);
