Chicago Board of Trade

The Chicago Board of Trade (CBOT), is an American futures and options exchange that was founded in 1848. On July 12, 2007, the CBOT merged with the Chicago Mercantile Exchange (CME) to form CME Group. CBOT and three other exchanges (CME, NYMEX, and COMEX) now operate as designated contract markets (DCM) of the CME Group. Provided by Wikipedia
