I believe that he is saying that you show your cards with a GTC. They see where people have their buys in and they move the price down to your price. In this case, you probably get diltion(sp???) shares. Since people that bought higher probably won't be selling to you down there for a loss. (thus the drag.) If you wait and see if the price drops down to the price you want, then you just put your order in then (I am assuming a market order), the price will come up to you. I guess you would get it at the ask instead of at the bid (so it will be 1 tick up). I may just be babbling here, but I think this is right. IMO
