[torero]

I'm torn on siding with or against ws' comments. It's true it takes alot of time to come up with something useful enough to even consider trading it real time. Even then, these are not suitable for daytrading (swing or higher). Having said that I've found a few systems through data mining but took me a 2 years drudging at it. So, if you have time and 2 years, then learning this side of trading is very valuable. These data mining finds have to be done with extreme care (ie. very skeptical) or it'll be your $$$ with a wrong assumptions or operating with full knowledge of the matter involved.
