Sorry.. but no. You just don't see patterns like we did today. A HUGE dip + a HUGE recovery in the matter of half an hour or so.
If people were selling.. it would stay way down.. and it's not.
There was a new MM... who has a history of being shady, and low and behold, after the shake his L2 numbers are back to a normal MM's numbers. We haven't seen ANY MMs on the list w/block sizes like his.
We obviously can't confirm this w/out an SEC investigation, but *I* think it's pretty clear what happened.
