If you place a trade the MM buy at the bid and sell to you at the ask. That is called spread. Now if he hold it a little longer while the price drops, he sell you at the old top and MM buys at the new lower price, increasing his spread. You can stop that by bidding at the bid and placing a limit order but for you to get filled the bid price has to drop below the present price and then the MM will only trade if he can make a profit. This is done all the time with most brokers, that why on line is so much better for us lowly customers!!
