As a totally pragmatic point - if the market is in such free-fall that it matters that your order got in a 10 thousandth of a second after somebody else's, instead of before, you probably lost at least 5 to 10 times as much during the time it took somebody to type the damn order in and hit enter.
At that point, you have *bigger* things to worry about. [unhandled content-type:application/pgp-signature] | |
