We actually talked about that today here in the ES journal. I said someone starting out could take $100 and learnt o trade the ES micro, but someone disagreed with me and said that someone needs at least $1100 to trade micros. Your $50 is easy enough to come up with, but even I think that that is too little by about half.
No, I didn't say someone needed $1100 to trade micros, I simply said it was better (safer) than $100. Heck, the only thing you "need" is whatever the broker requires, which happens to be $50 at Ninjatrader I believe. That's nuts.
