RE: [amibroker] Date for last avilable data

["ta" <tagroups@xxxxxxxxxxxxx>]

The following code correctly identifies the the beginning and ending data dates for the active symbols. It uses the same beginning and ending date for all other sysmbols. Do you know why? TIA

 

FirstDataDate = BeginValue( DateTime() );
LastDataDate = EndValue( DateTime() );
_TRACE(Name() + " FirstDataDate: " + WriteVal( FirstDataDate , formatDateTime ) + " LastDataDate: " + WriteVal( LastDataDate, formatDateTime ));

AddColumn(FirstDataDate, "FirstDataDate", formatDateTime );
AddColumn(LastDataDate, "LastDataDate", formatDateTime );

I am trying to run an explore to find the first and last dates that I have data for all the symbols in my eod database. I have struggled with it quite a bit. How would you suggest I should go about solving this problem. TIA

 

d = DateNum();
LastDataDate = ValueWhen(LastValue(BarIndex()), d);

AddColumn(LastDataDate, "LastDataDate", formatDateTime );
