Hi, I have only been trading for a couple of months now and have come across a few questions that I write down in a book to ask when I come across someone who might know the answer. Unfortunately I do not live in a "big business" metropolis so knowledgable traders are few and far between. I was hoping some of you guys could help me with one question that really bugs me and seems to keep coming up over and over again. This question pertains to placing orders on NASDAQ Level II. At times I notice that a huge amount of buying volume comes in at a particular ask price--I am talking about the kind of volume that causes a spike on the chart. This continues to go on for 3-5 minutes and the ask price never raises. My question is if there are these people buying consistently over a 3-5 minute period of time, why do the market makers not raise the ask price? Obviously there is a large buying interest in the stock, so why not get more money on the shares by periodically raising the price (and make me a profit in the process)?
