Chicago Board of Trade.

Its development history is as follows:1At the beginning of the 9th century, Chicago was the largest grain distribution center in the United States. With the continuous concentration of grain trading and the development of forward trading methods, the Chicago Board of Trade was established on 1848 by 82 grain traders. After the establishment of the exchange, the trading rules have been continuously improved. 1865, the forward contract is replaced by the standard futures contract, and the deposit is implemented.

. In addition to providing futures trading of corn, soybeans, wheat and other agricultural products, the Chicago Board of Trade also provides futures trading markets for medium and long-term US Treasury bonds, stock indexes, municipal bond indexes, gold and silver, and provides options trading of agricultural products, finance and metals. The futures prices of corn, soybean, wheat and other varieties on the Chicago Board of Trade have not only become important reference prices for agricultural production and processing in the United States, but also become authoritative prices in international agricultural trade.
