I asked that question in the newbie forum already but nobody answered. So i thought i would try here.

Hey, Guys! In trading one of the possibilities to judge a "System" is to calculate the Profit Factor. (Gross Win / Gross Loss). For example i make 500 bets $100 each and win 55% So it would be:
(275*95=26.125) / (225*100=22.500) = 1,16 Profit Factor. Do you guys have anything similar to that? What would be a "good" and what a "realistic" number?

Why do you think this profit factor is a good way to judge a systems results versus more traditional metrics?
