Hi,
That's not an easy question. There is certainly a lot one can do with power
basic. However, if you want a system optimisation with lets say upto six
variables and test combinations of setups entries and exits over a large
portfolio, then such an optimisation by brute force is going to take you for
ever. So I guess, I wouldn't start from Metastock. Have a read of Katz &
McKormick's Encyclopaedia of Trading Strategies. This has quite few good
ideas on portfolio testing & genetic optimisation in particular. If it were
me starting out, I'd probably export the data from MetaStock and then
develop a trading strategy testing tool in either Visual Basic as being
quick or Visual C++ being more efficient.
Not sure if I've helped.
