Re: [amibroker] AA/AFL: How many bars within date range

[uenal.mutlu@xxxxxxxxxxx]

Hi Herman and all,
sorry, I was a little bit unclear in my question. I indeed 

meant the date range fields one 
can set in AA. 
The solution below is exactly what I was looking 
for.
BTW, it is a very interesting (hard to find, maybe tricky) 

solution. Combining 
the required filter here with the 
usual filters of <FONT 
face=Arial>the system works too, that's wonderful.
On the other hand, IMHO such a function belongs to 
AFLs core lib.
Thanks to all,
UM
