Attain Capital is similar but much more professional than collective2. Walter Gallwas is a very nice guy as well. If you have documented returns I'm sure he'd be interested in making a system available for lease to his clients. He also gives credit to the systems that perform well in his weekly report so you could get lots of customers very quickly. http://www.attaincapital.com
Attain is nice, and definately more professional - but I'm looking for other sites like collective2 - that just play the middleman between system "vendor" and "customer" - for a cut. Not places that trade systems for clients.
It is not bad, but only stocks, ETFs and mutual funds can be traded. Navigation was a bit confusing...
No, I'm just a satisfied customer. I'd love to see more systems available there since the only results he sends out are of ACTUAL trading.
