Security and commodity exchanges are trading posts where people meet who wish to buy or sell. The exchanges themselves do no trading; they merely provide a place where prospective buyers and sellers can meet and conduct their business.

There are the cotton exchanges in New Orleans and Chicago; the Mercantile Exchange, which deals in many farm products, in Chicago; and grain exchanges in many of the large cities of the Midwest. Some exchanges, like the Chicago Board of Trade, provide market services for several kinds of products. These trading posts where products may be bought or sold are called commodity exchanges.
