All-or-None

Orders That Must Be Filled in Their Entirety at a Single Price

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.

The following table lists AON-eligible CME and CBOT products and includes the associated AON minimum order quantity thresholds and allowable counterparty minimum thresholds for each product.

Benefits of AON Transactions

  • Efficient and complete execution of large orders – no partial fills
  • All contracts on the order executed at a single price
  • Allows participants to take maximum advantage of pit liquidity
  • Facilitates the execution of sizeable spread and combination trades
  • Designed to meet institutional trading needs
