I was reading my Futures magazine about the Top Ten Trading System and they looked interesting. For paying 1-2k for a trading system, you could get these great long term systems averaging over 40% a year. I researched into some of the systems like CheckMate and ReadySetGo. I look at their performance and then I went to some Systems Brokers who ran those systems but their actual results are Far from the hypothetial performance. For Example, Dean Hoffman says his personal account is up over 200% last 2 years. I looked at the last 1 year performance of CheckMate, Interplay, Fusion at Attain System Broker and those systems were like up 10% last year. And the hypothetical results were suppose to be like 50%. My question is... Is it really possible to pay 1-2k for a system and have a systems broker make 20-50% a year with that system for your capital? Why is there such a difference between the hypothetical results and the actual performance at system brokers? I thought commodities were liquid and slippage was limited. Thanks!
