Hello,
Sorry there was one typo, should be AddColumn instead of Addtextcolumn,
as below:
function RangeBarLast()
{
Result = LastValue( ValueWhen( Status("lastbarinrange"),
BarIndex() ) );
return Result;
}
EndBar = RangeBarLast();
dt = DateTime();
Filter = 1;
AddColumn(dt[ EndBar ] , "End Date", formatDateTime);
Hope this helps.
Best regards,
Tomasz Janeczko
