Hello Myst, I've heard a great deal about X_DEV but haven't had the time to look at it yet. Lots of people saying lots of good things about it. When I get a chance I expect I'll delve into it. If you have anything you'd like to discuss on improving the AIM algorithm, please feel free to post it here. From time to time I'll be throwing out ideas for discussion -- well while I'm at it, why not start now... Any thoughts on using the W%R to modify AIM recommendations? Regards, Mark. <A HREF="http://www.automaticinvestor.com" target="_new">http://www.automaticinvestor.com</A>
