Depth of market
Most online trading platforms include a "Depth of Market" or DOM feature which typically shows graphically the quantity of bids and offers currently known in the electronic market. For example: If the last trade were 9755 in January CBT Beans a DOM display would show not only where trades were occuring, but the number of contracts bid or offered at that price and disclosed quantities bid or offered at prices surrounding the last traded price.
