For Market Data Distributors that support trading systems-

Currency and Livestock outright options executed at a Trade Price of 0 (zero) will be considered a trade at cabinet.

Equity and Eurodollar outright options executed at the lowest allowable tick value (non-zero) will be considered a trade at cabinet.

Buy-Sell option spreads executed at a Trade Price of 0 (zero) will be considered a trade at a 0 (zero) differential and leg prices will be assigned accordingly. These do not represent a trade at the Cabinet Price.

Buy/Buy and Sell/Sell option strategies must be entered with an order price no less than one tick per leg. For example, an straddle that trades at a tick of .25 per leg must be entered with a price of .50 or greater

CME is currently reviewing Cabinet pricing for all CME Globex options to support order entry at the actual Cabinet Price.
