All-or-None (AON) orders are orders executed in the open outcry venue that must be filled in their entirety at a single price. AON transactions are permitted only in certain products and must be for a quantity that meets or exceeds the exchange-specified AON minimum quantity for that product. An AON order may be executed opposite multiple counterparties provided that each opposing party to the AON order meets the exchange-specified minimum counterparty threshold.
For additional information on AON transactions, please see our CME & CBOT Market Regulation Advisory Notices.
