Level 2 Bid/Ask are the same people. I have tried several times to sell some shares. But NITE or CSTI would ALWAYS jump in front of me .001 lower on the Ask. We would walk it down just above the Bid before I would take it off. I am NOT selling at the BID as a matter of principle. Although I wish I had several times because that money would have been doubled elsewhere this past month. This stock is about on it last breath but I will wait for the fat lady to sing. A high note could change everything.
