I don't see where you are getting 500%/year.Its not about being one of the good ones or not.
But saying that making 500% a year just to cover you commissions is realistic for retail traders, is just really silly guys.
Maybe 0.1% of traders can do that if they have found some arb strategy that guarantees making money.
But its not even worth considering as realistic for 99.9% of retail traders.
Saying otherwise is something that a newbie trader would come out with.
Again, I have never traded YM.. but if he's (YMmagic) is making $25 a point (not sure how many contracts that is), and a round trip is $8ish.... and he gets 20 points on one of his winners, ie $500... $8 doesn't sound like much to me. Am I missing something? Again, I don't trade it.
