but the price doesnt have to move for your limit order that is say in between the bid and ask price. all you need is someone with the stock to want to sell it. plus if you let them fill parts of your order you are guananteed to pay higher prices on the rest of it.

sure if its a high volitility stock and you think its going to skyrocket soon, you should buy right now and not miss out, but i dont know anyone that is this smart. so far one one has showed that saving that 1/4 or 1/2 point which is several hunderd dollars on even smallish sized transactions, really costs you money. as i find that the sale almost always goes thru right away. this shows to me that the market makers that are putting up a spread will usually take a little less. forget about the theory behind it all, which i understand much better now, this is what i see happens.
