Tomasz,
Thanks as always for your reply.
Can you just clarify for me please where the number of quotes for a stock comes into the adline() formulae.
>>From the manual
adline = (Sum (advances) - Sum(declines))/(Sum(unchanged) + 1)
I'm assuming the sum is across all quotes in the database.
I can't see where the number of quotes for a stock comes into this ?
or anywhere in the afl I sent you on this.
Is the sum just across the quotes for the stock being displayed not all quotes in the database ?
I think that would explain it.
Regards,
Geoff

Hi,<BR>

If all your stocks had the same history length there wouldn't be a problem.<BR>
Unfortunatelly, because all have different lengths there is no constant that you<BR>
can add that will fit all.<BR>
