It is true that many day traders try to "figure out" what the market makers are doing based on the size of their bids and offers. That actually worked OK two or three years ago on the NASDAQ. The big houses figured out a way to counter that...they started using the ECNs themselves. On top of that, there are a few very, very large players in the day trading business. It has become increasingly difficult to "read" a MM on a stock, fat volume or thin. Additionally, I myself see examples of a MM backing away from a firm bid or offer almost every day. Today for example, a MM backed away from three separate orders that I placed to buy a stock from him, all at the same price. He did not move from the ask, and his size did not change, he simply refused to take my order and then about a minute later, he backed away. I have instant execution and nobody else was in front of me or behind me. Yes, it pisses me off, and yes, I could make a stink about it, but it happens all the time . As a day trader, I have already accepted the fact that the man with the hundred million is not going to telegraph his moves to me or to anyone else. In other words, if the stock is at 50 X 50 1/4, and ISLD (or ARCA or REDI or whomever) suddenly appears with an offer of 29,600 at 50 3/8, a rookie day trader who just bought the stock for 50 3/16 will assume the stock is going to go down and panic if it does. That's not the way I look at it. I assume that that guy is either a large day trader or a market maker, and I watch to see if he actually sells any of those shares. If the stock does in fact go down, (to say 48 7/8 on the bid, for example) and holds, and the big ISLD offer goes away, (he was never the best ask) and the stock moves back up, I know that it was probably somebody (I don't know who) either going long at 48 7/8 or covering his short position. Just part of the game. The MM is getting the best price for his client, or the elephant day trader held off the Big Bad Wolf again and walked away with cash. These whipsaws are orchestrated IMHO simply to shake out people who are trading on momentum. True, sometimes momentum works out, like when the stock breaks through a new daily high or low, but most of the time, the size on the bid or the offer is just somebody smoking somebody else. I've sat in the same room as a firm trader, and I have watched them work. It's not a simple or easy job. I don't bother to try and figure out the head games. I don't have enough money. I just try and figure out what the guy that is playing the head games is actually doing. I have no problem with that. <G>
