Sounds nice, but I guess the first step is to take control away from the likes of Citadel / Kenneth Griffin since they take advantage of all that information and they already get to bid against every order placed in real time.
I think our government should definitely get on that. In the meantime forbidding this kind of play aka taxing the living shit out of day-trading (like the current short-term/long-term gain system but actually painful in the very short term) should be pretty simple to implement.
