Previous Value

["Jeff Gholson" <jgholson@xxxx>]

Hello 
to All!

Just 
got the lastest issure of Active Trader Magazine....always like to play around 
with the systems they present in "The Trading Systems Lab" 
section...

This 
month they present a system based on a Volume Weighted Moving Average.  
Everything is fairly simple to code into AFL, with one little exception...to 
start the calculation of the VWMA you must have the "previous" VWMA to preform 
the calculation. There is my problem...how to get a "previous" value of an array 
when you haven't preformed the first calculation of the 
array. 
 
All 
you "Codies" out there...any suggestions?
