The delisting of a futures variety means that all contracts of a futures variety are withdrawn from the market for some reason and no longer traded. For example, treasury bonds futures and mung bean futures, which were once very active.
The delisting of futures contracts refers to the phenomenon of automatic delisting after the last specified transaction. The delisting date of each contract has been determined on the day of listing. When the Shanghai Copper 0807 contract was listed on July 8, 2007, it was clearly stated that it would be delisted on July 5, 2008.
