分笔统计涨停时的处理

源码如下

IF DATATYPE=6 then exit;
ZF:=C/DYNAINFO(3)>=1.099;
TF:=DYNAINFO(3)/C>=1.110;
bidoor:=5000; //大单门限
sudoor:=80000; //超大单门限
buy:=IF(ZF,VOL,IF(TF,0,BUYVOL)); //应该是这里有问题，不过想来想去没搞懂
sell:=IF(ZF,0,IF(TF,VOL,SELLVOL)); //涨停时记SELLVOL为流入，故为buy，跌停反之
sub:=IF(buy*C>=sudoor,buy,0);
sus:=IF(sell*C>=sudoor,sell,0);
bib:=IF(buy*C<sudoor AND buy*C>=bidoor,buy,0);
bis:=IF(sell*C<sudoor AND sell*C>=bidoor,sell,0);
lib:=IF(buy*C<bidoor,buy,0);
lis:=IF(sell*C<bidoor,sell,0);
