sorting a single symbol over X bars is OK for speed, or for single bar between symbols is not bad for speed.
From what i saw of your loop code you were wanting to sort over a watchlist
of 200 symbols, for each symbol against every other symbol for every bar. This will be very very slow

Graham, Thanks. I find the sorting and ranking within the Osaka routines to be very fast. I am going to try saving a binary version of the table created using Osaka and then from within my indicator code recall and load the table into memory and index into it for just the rank of the ticker I have displayed in my chart therfore only needing to create one array instead of 200 which I think (hope?) I can do. I think I should then be able to plot this without incurring a performance penalty.....thanks for your help. regards, Tom --- In amibroker@yahoogroups.com, Graham <[EMAIL PROTECTED]> wrote: > > If you need the value for every bar then you will need to run the ranking > for every bar, including creating the data files for every bar. ie within a > loop > There are some sort and rank AFL in a library that allow similar ranking > using staticvarget, but again these will need changing to within a loop to > get the ranked values for every bar. > Just remember that sorting symbols against each other will slow the > execution down by a very large amount, the more symbols and more bars > included will determine the boredom time you will encounter > > -- > Cheers > Graham > AB-Write >< Professional AFL Writing Service > Yes, I write AFL code to your requirements > http://www.aflwriting.com > > > On 11/01/07, trb0428 <[EMAIL PROTECTED]> wrote: > > > > Hi Graham, > > > > I am using the Osaka plugin to rank and sort a list of stocks. > > From this, I am trying to create an indicator which will display the > > rank of the stock for each bar.
