Are you kidding... you havent been watching L2....
SBSH has been the major MM on the BID since .30 levels....they have been the ones buying all the shares when you sell on the bid....
They provided much support and bid competition between other MMs... as the profit taking takes place. SBSH moves down and waits... sits on the ask to sell and make some nice change..... but as soon as he is back on the Bid... its the bounce..
