Techniques for trading commodities on a private trading system and not regulatedby the government

摘要

Techniques for assisted trading in a market for commodities include designating a non-trading central authority (110). The central authority screens entities to identify authorized traders (120). If agreement is subsequently indicated by input from each trader of at least two contracting traders among the authorized traders (132), then the central authority automatically constructs a standardized sales contract (136) for the commodity.
