While I was sweeping the floors at knight equity, I asked one of those High school buddies I ran into on the trade floor, and pinks are no different. Even the ECN network is the same. I ran into a few folks at Direct Edge while I was moping under their desk. They have to keep track of EVERY TRADE every day..... pinks included.
Posting Mis information in front of someone who sweeps floors at Knight, is a mistake.
