      If the market maker is a size buyer or seller of shares, another trickthat he will often employ (sometimes in conjunction with the aforementionedtrick) is to "hide" the size. For example, if the market maker is a sizeseller of stock, he may only reveal a small portion of the order. He willgo to the inside ask, sell a few thousand shares, and then "reload"(refresh the ask). When those shares are taken, he will reload again.. .andagain.. .and again. You will see these trades in the TOS. When you see amarket maker reloading, there are a number of factors to consider. First,who is the market maker? If you have been watching the stock closely overthe past days and weeks, you will have developed a feel for who the "key"market makers are in the stock. Is the market maker who is reloading a keyplayer? If so, add more weight to this consideration. If he is not, takenotice. It could be that the market maker only has a limited number ofshares to offer and will soon be done selling. One way to quickly determinewhether or not the market maker is a key player in a stock is to use theindicator that tells which market makers have been at the inside ask themost times during the day. If you do not have this tool, I highly recommendthat you switch to a platform that does have it. This is one of the mostpowerful decision support tools available, and one that you cannot affordto trade without.
