NWPN I'm not saying this is the case here, but it's possible...

Another (MM) practice is the "no intention to sell/buy order". It's basically a fake order. They will post up a huge sized trade on one side of the bid or ask in order to create a false sense resistance or support. Once they see the action they want to see they remove these bids, sometimes you'll hear people say, "that 2 million share bid just got pulled off". These orders are easy to spot as they tend to stay away from the market action as they obviously wouldn't want that order to accidentally fill if the market moved too quickly, and the size of the order is going to be not typical for the volume being traded. No trader wants to buy 1 million shares of a stock that has only traded 5 million shares a day unless he wants to own the float.
