Trading Practices



CME Clearing accommodates special types of trades to meet the business needs of our diverse base. These include large orders and privately negotiated transactions that require clearing.

Block Trading


A Block Trade is a privately negotiated futures transaction executed apart from the public auction market, either on or off the exchange trading floor.

All-or-None (AON) trades are specially designated large order trades that must be filled completely or not at all.

Mutual Offset System

Exchange for Related Positions (EFRP) transactions are privately negotiated trades that include Exchange for Physical (EFP), Exchange for Risk (EFR) and Exchange of Options for Options (EOO).

The Mutual Offset System (MOS) is a partner program between CME and SGX that enables traders to open a futures position on one exchange and liquidate it on the other.
