Yes, I agree proving it is important.
I am about to release my trading system. The website goes live on Wednesday (it's up now, but has typos). I have a book of paper trades that are showing an 80% win rate (some more, some less). They are generally small wins tough. Most are under $100.00, with a few good ones closer to $1000.00 or more every 10-12 trades.
To prove this, I have decided to subscribe to Collective2 at http://www.collective2.com/cgi-perl/c2dashboard.mpl
For those of you that don't know, Collective2 is a subscriber website that independently tests people's trading system. Then they publish the results.
it costs $98.00 to subscribe to have your system tested, This is done by entering trades through thier system to log them as you make your entries, and exits. It produces a hypothetical fill, and accounts for typical commissions and fees. The results are published on your page.
The cool thing about it, is people can subscribe to your page, and use the auto trader function to automatically trade thier accounts with your signals. Collective2 takes a commission and you get the rest of that subscription fee. so, if I charge a $150.00 per month subscription fee, I may take home $100.00 per subscriber.
Once my system proves itself, I am sure it will not be hard to get subscribers. Although, for me I am doing it to prove the concept publicly more than the subscriptions I may get.
Right now, I am playing with it as a test system. I am not ready to go live yet. I am going to get a few dozen trades there in the 'Test' mode to sharpen my execution, and smooth out the emotional stuff now that the pressure is going to be on. After that phase is worked out, then I will publish it live.
After that, I either stand the trial by fire, or I burn.
Maybe the 7-10 rules could be tested the same way.
