Thanks Richard,
This is what I expected. I'm surprised that MetaStock developers
have not improved the way parameters are optimized at this late date.
Since the advent of low priced computing, the field of Operations
Research has produced many algorythms to speed up the process of
finding global optimum solutions. Single stepping through all
possible combinations is low tech, at best!
