LOL unfortunately the computers are gonna take over the shorter time frames. If it's mechanical, like most scalping is, the black box will be doing it instead of you.
Think of it from a business standpoint of the major IB players (particularly Goldman) and even the standard prop firms. What is more efficient, cheaper and easier to maintain? A human being or a black box. What is faster and more consistent?
Besides the big players want the NYSE's created innefficiency/racket for themselves.
