Re: [amibroker] Another PREV example

["Tomasz Janeczko" <amibroker@xxxx>]

Hello,
 
This is the reason why I think it is a good idea 
NOT to have PREV in AFL.
In 80% of cases things may be coded without it in 
much more efficient manner
(remember MS's PREV is very slow). The rest 20% of 
cases could be coded
in script (also much more 
efficiently).
 
Best regards,

Hey 
that worked perfectly!

It 
just goes to show that there is always a different perspective for every 
problem.  I never thought to use the barssince 
function.

Hi All,I've been struggling to figure out how 
to code an MS indicator in AFLwithout using VBScript or JScript.  
The function is pretty straight forward,but the solution still eludes 
me.  Here is the function:      
If(Month()<>Ref(Month(),-1),1,PREV+1)It is recursive, which 
makes it very simple to understand.  It is anindicator that plots 
the current trade day number of the month.Can anybody offer any 
ideas on how to get this going?Thanks in 
advance!DanielYour use of Yahoo! Groups
