With only 70+m issued shares and mkt cap on 3.5m the stock often has a large spread between bid/ask. I not the same player want 100k+ each day at 4.6 must have an Algo as each time a bid comes above him he is there by the time you press "submit"... do details are available "as your entering you big details. He pulls out (or algo does) after 5.1 bid. good exercise to watch
