30 ES contracts requires $30000 margin. ES intraday moves UPTO 20 points either way. I work on 0.50 to 1.5 point move of the index. Each index point is worth $50 x 30 cars=$1500 per point. Now what would be 12.8% of $30k initial invested capital? 2.56 points on AVERAGE SO FAR. I do have more funds in the account, but that's not accountable as invested capital, that would only be so if extra margin is required. OK, now if you take firms that offer $500 margins, 30 contracts would need $15000 margin, though if the return in points on average is the same as above, the return on investment is higher. There are days when there are no trades for me, but you were talking about daily average I assumed.
