Title: Re: [amibroker] Re: Find symbols with no bars
You need to decide how many/few bars you want to accept. To get an idea what you are dealing with Explore your database with an exploration like this:
DT = DateTime();
DN = DateNum();
NumBars = Cum(V>0);
NewDay = DN != Ref(DN,-1);
FillBars = Cum(V==0 AND Status("BarInRange"));
SN = Status("StockNum");
NumDays = Cum(Newday);
Filter = Status("LastBarInTest");
SetOption("NoDefaultColumns",False);
AddTextColumn(MarketID(1),"Market",1.0);
AddTextColumn(SectorID(1),"Sector",1.0);
AddTextColumn(IndustryID(1),"Industry",1.0);
AddTextColumn(FullName(),"FullName",1.0);
AddColumn(C,"$Close",1.2,1,2,60);
AddColumn(MA(V,60),"MA(V,60)",1.0,1,2,60);
AddColumn(FillBars,"NoData",1.0,1,2,60);
AddColumn(SN,"#",1.0,1,2,50);
AddColumn(NumBars,"#B",1.0,1,2,50);
AddColumn(Numdays,"#D",1.0,1,2,50);
AddColumn(DT[0],"From",formatDateTime,1,2,150);
AddColumn(DT[BarCount-1],"To",formatDateTime,1,2,150);
