主题：加了过滤集合竞价代码无信号

那代码怎么写？

if  dynainfo(207)>opentime(1) and dynainfo(207)<closetime(0) and islastbar  then begin

refh:=ref(h,1);
refl:=ref(l,1);
name:=strreplace(stklabel,'13','00');

if holding=0 and h>refh then
  begin
    tbuy(1,1,lmt,dynainfo2(7,name)+3*mindiff,0,'',name);
    buy(1,1,LIMITR,max(refh,o)+3*mindiff);
  end

if holding>0 and l<refl and enterbars>0 then
  begin
    tsell(1,1,lmt,dynainfo2(7,name)+3*mindiff,0,'',name);
    sell(1,1,limitr,min(refl,o)-3*mindiff);
  end
end
