Hello,
DateNum is a number in the format YYYMMDD
where YYY is year-1900, MM is month, DD is day.
2007-1-1 should be written as:
1070101
Best regards,

dear members
I tried the following code in commentary(to find bars between 2
dates) as suggested by TJ.
bi=BarIndex();
bi1=ValueWhen(DateNum()=2007-1-1,bi);
bi2=ValueWhen(DateNum()=2007-12-1,bi);
numbars=LastValue(bi1-bi2);
WriteVal(numbars);
(1)but i got the following error-
Error in AFL formula:
bi2=ValueWhen(DateNum()=2007-12-1,bi);
numbars=LastValue(bi1-bi2)
-------------------------^
Error 29.
Variable 'bi2' used without having been initialized.
(2)plz in what format DateNum accepts the date? whether in quotes?
regards
mahesh
