• High/Low/Last prices
• Fixing prices
• Marker prices
• Close prices
• Net change

CME Globex Market Segment Gateway Enhancements  - January 26, 2020

Starting Sunday, January 26, 2020 (trade date Monday, January 27), CME Group will introduce the following Market Segment Gateway (MSGW) enhancements to further safeguard CME Globex infrastructure.

With this enhancement, if a Market Segment Gateway (MSGW) iLink session sends a network packet with an incomplete message, that session will be subject to additional processing to ensure the stability of the platform. This processing results in at least 3 microseconds before the message(s) can be sent to the trading engine.

iLink messages impacted by this enhancement will be flagged in the corresponding Acknowledgment sent from CME Globex.

Customers are strongly encouraged to ensure all messages are contained within a single network packet by the following methods:

• Ensure any packet sent to CME group contains only complete messages
• Limit the number of quote entries in a mass quote message that fits within a single TCP packet
• Disable nagling, an algorithm that concatenates a number of small buffer messages to decrease the number of sent packets, on your order routing systems

As a reminder, conduct that disrupts, delays, or overloads the systems or operations of the exchange may be deemed to violate Rule 575 (“Disruptive Practices Prohibited”) or other rules, including Rule 432.Q. (“General Offenses – to commit an act which is detrimental to the interest or welfare of the Exchange or to engage in any conduct which tends to impair the dignity or good name of the Exchange”). Rule 575 further provides that it is a violation to enter or cause to be entered an order where the intent at the time of order entry is to cancel the order before execution. It is also a violation of Rule 575 to intentionally or recklessly enter or cause to be entered an actionable or non-actionable message that may cause an adverse impact on the orderliness of the markets.

Customers interested in finding out how MSGW enhancements would impact their iLink sessions should contact their Global Account Manager in the U.S. at +1 312 634 8700, in Europe at +44 203 379 3754 or in Asia at +65 6593 5505 for additional information.

In internal testing, iLink round trip times at the 75th percentile and above increased at least 10%.

Please review the Client Impact Assessment for additional information on these Market Segment Gateway enhancements.

Staring on Monday, November 4, the CME Globex MSGW Enhancements will be available for customer testing in New Release. In addition, the new FIX tags for this enhancement will be available for customer testing in CME AutoCert+ Test Suite - MSGW Protection Enhancements. Certification is not required for these MSGW enhancements.

Mock Trading Session:

CME Group will offer two customer mock trading sessions on Saturday, December 14, 2019 and Saturday, January 25, 2020 to support customer experience with the MSGW enhancements in the CME Globex production environment. Customers are required to register in advance in order to participate in this mock trading session. The mock trading session script will be announced in future CME Globex Notices.
