请高手把这个大智慧的分时指标改成通达信的，谢谢

A1:=(VOL/CLOSE)/3;
A2:=SUM((IF(((A1>40) AND (CLOSE>(REF(CLOSE,1)))),A1,0)),0);
A3:=SUM((IF(((A1>40) AND (CLOSE<(REF(CLOSE,1)))),A1,0)),0);
A4:=SUM((IF(((A1<40) AND (CLOSE>(REF(CLOSE,1)))),A1,0)),0);
A5:=SUM((IF(((A1<40) AND (CLOSE<(REF(CLOSE,1)))),A1,0)),0);
A6:=((A2+A3)+A4)+A5;

A8:=((IF((ISLASTBAR=1),((100*A3)/A6),0)));
A9:=((IF((ISLASTBAR=1),((100*A4)/A6),0)));
A10:=((IF((ISLASTBAR=1),((100*A5)/A6),0)));
