Market Makers set SHIT up, believe that 100%, there are no buys for every sells down here. They are in it for the BIG BUCKS. There's not a DAM thing the SEC can do to these guys.
This is one BIG reason why they LOAD UP on things they know are coming, FYI TBEV
That said, try and change your trading strategy to noticing HOW Time Sales is setting up in conjunction with L2. Never look at one without the other, never!
