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.
The price updates whenever someone buys or sells, so doing that once a day may be a bit difficult to implement. Forbidding day-trading / imposing a minimum holding time on the other hand may be easier.
I am very happy with my RX6800 based Asus Zephyrus G14 laptop :)
