About the Global Command Center (GCC)

All CME Group customers are welcome to contact the GCC for support. However, for critical order status assistance, such as requests related to obtaining confidential order and trade data, the GCC requires a valid CME Group login with proper FirmSoft mapping and dual-factor authentication (2FA) enabled to provide the most secure and expedited service.

To expedite critical order status assistance from the Global Command Center (GCC), please complete these three steps:

1. Create a CME Group Login if you do not already have one.
2. Register for Access: Register for both FirmSoft Access and Two-Factor (2FA) Authentication using a phone number unique to you.
3. Test Call: Once you have access to FirmSoft and 2FA, we recommend making a test call to the GCC during a non-emergency/non-critical time when you have working or filled orders in the market. This will familiarize you with our order status and cancellation protocols and ensure your CME Group Login is recognized. For security purposes, our analysts will verify your information if 2FA is not recognized or if you call from a non-2FA registered phone number.

Order status and cancellations may require specific details about your order(s): Firm ID, Trader ID, Globex User Signature (GUS), Globex Firm Id (GFID), Account Number, Trade Order Number (TON), Specific Instrument(s), Order Quantity, and/or Date and Time of Order

Please prioritize order(s) for cancellation based on market and execution risk. The GCC will confirm your cancellation request before execution, verify the cancellation is complete, and review the status of your remaining orders with you.

If you have any questions, please contact the CME Global Command Center:

Support is available 24 hours a day, beginning at 11 a.m. Sunday through 4:30 p.m. Friday, Central Time.

This policy outlines procedures to safeguard CME Group markets and systems from disruptive behavior.

The GCC continuously monitors trading activity. If potentially harmful behavior is detected, whether via iLink or network connections, and is not promptly corrected, the GCC will intervene by:

• Closing the ports associated with the disruptive iLink session.
• Blocking problematic IP Ranges.

Please note, all such actions are subject to regulatory review. Existing working orders in the affected session will remain active unless Cancel on Disconnect (COD) is enabled. COD will cancel all day and session orders. Traders without COD can cancel orders using Kill Switch, FirmSoft, or by having a registered contact call the GCC.

To avoid disruptions, trading entities should:

• Monitor Order Activity: Continuously monitor order flow and executions for anomalies.
• Manage Order Rejections: Implement robust systems to handle and resolve administrative and business-level order rejections.
• Maintain Systems: Ensure trading systems are properly maintained and configured to handle potential issues. CME Group expects continuous monitoring of all electronic activity. Failure to do so may invite more regulatory scrutiny.

Disruptive behavior resulting in port closures or IP blocks will incur a $1,000 fee per affected session, up to $10,000 per event. This applies to iLink sessions trading CME Group products. Sessions trading solely on partner exchanges are governed by their respective rules.

The GCC will make the best attempt to notify the GCC Outbound iLink Technical Contact via email for port closures. For IP blocks, the identified circuit owner will be contacted.

The GCC calculates and publishes daily and final settlement prices for all core CME Group futures and options products, as well as provides settlement derivation services for our partner exchanges. Because these settlements determine the payouts and collections processed by the Clearing House for all CME Group customers, the accuracy and transparency of these prices are crucial for maintaining customer confidence. The GCC collaborates closely with various departments, including Product Launch, Research, Business Line Management (BLM), Client Development & Services (CD&S), Market Regulation and Clearing, to ensure the implementation of the most appropriate methodologies.

Further information is available on the Settlement Wiki.

The GCC sends notifications via the CME Globex Targeted Messaging System during emergency situations. If it is determined that an event is likely to affect a significant number of customers and/or has the potential to require an emergency market halt, the GCC posts a message on CMEGroup.com and notifies subscribed customers via:

• Email
• SMS text

If markets are halted, the GCC will send messages at 15-minute intervals throughout the event investigation. Once the issue is resolved, the GCC will announce the market re-opening time.
