VNDM is an obvious short seller. Period. when there is a run, he steps in. when there is a drop, he moves down. When other market makers join him, he moves away. He does not want to short more; he wants to prevent a run.
Most brokerages route their orders through ETMM (ETrade) or NITE; some through UBSS; fewer through HDSN (Hudson). Virtually none of them route orders through VNDM or VFIN. So when you see those two on the offer, it is clear they are there only to stop a run or encourage a decline.
$$$$HNSS$$$$ you don't know which way that you want to flop. It is obvious that you are trying to get cheapies. You'll have a positive post and then negative, mostly negative. Go back and read your own posts and you'll see what I mean. If I'm wrong go outside and shoot yourself in the foot, because your not helping the stock at all.
