It has been fun to search the yahoo archives back to 2002 and see names of a lot of the original folks who got on the Amibroker bandwagon back in the early days, many of whom are no longer around (at least not posting like they used to).  Boy, how the program has evolved and improved over these many years.
 
I was looking back there in the archives for messages on the Osaka Plugin (which is still on my hard drive since 2002 but which I have never used).  Maybe now......
 
I have a need to take a watchlist and position rank several columns of calculations and determine the postion rank of the ticker for that calculation; then do the same for another column (calculation), get the position rank for that additional column, and then combine the position ranking numbers for the columns for each ticker, sort of to get a Master ranking parameter.
 
My question is: what new features in AB might help accomplish this?  Surely the Osaka Plugin (2002 vintage) is not the only way to do what I want.  I have not really studied nor used Static and Dynamic variables---is this the set of commands that I would use with looping to get position ranks of a watchlist?
 
I did find and just tested some code from the Library which used just these tools (variables and looping) and it was painfully slow and would not really work for the application I have in mind.  I am uncertain if the code in that example can be modified to make it faster. 
 
Any suggestions about this age-old question/problem, given the many advances of Amibroker since 2002??
 
Thanks for any ideas (the more specific the better).
 
Ken
