Market making refers broadly to trading strategies that seek to profit by providing liquidity to other traders while avoiding accumulating a large net position in a stock. In the simplest terms, a market maker helps facilitate the execution of a trade by providing a continuous bid-and-ask market for a futures or options contract to any interested party, hoping to make a profit by exploiting the difference between the two prices, known as the spread. Intuitively, a market maker wishes to buy and sell equal volumes of the instrument (or commodity), and thus rarely or never accumulate a large net position, and profit from the difference between the selling and buying prices.
