This metric of YOURS, n to 1 margin, is somewhat incorrect, as far as trading futures is concerned. It doesn't matter one iota if you put up $400 or 4M per contract. In the ES the tic value is 12.50. That fact has absolutely nothing to do with the amount of "margin" a participant is required, or otherwise chooses, to put up, period. Unless you traded 10 contracts, talking about some equivalence is nothing more than a fisherman's tale. BTW, nothing wrong with capturing 12.25 pts on however many it was.
