Critical System Updates

UpdateUpdate - Leg Security Description Change on iLink Security Definition Request - March 29

† Denotes update to the article

On †Sunday, March 29 (trade date Monday, March 30), to better align with iLink 3 Binary Order Entry Protocol, CME Globex will change FIX tag 620-LegSecurityDesc validation for the Security Definition Request (tag 35-MsgType=c) message.

With this change, if the tag 620-LegSecurityDesc is not present, but the Security Definition Request contains tag 602-LegSecurityID, CME Globex will accept the message.

The Security Definition Request will be rejected with a Business Level Reject (35=j) message if the Security Definition Request:

• does not contain both tag 620-LegSecurityDesc and tag 602-LegSecurityID, the reject message will include the following tag 58-Text=<Business Reject: Required Fields Missing 'Missing fields: LEG_SECURITY_DESC (620) and LEG_SECURITY_ID (602)'>.
• does not contain tag 620-LegSecurityDesc, but contains an invalid value for tag 602-LegSecurityID, the reject message will include the following tag 58-Text=< Business Reject: Required Fields Invalid 'Invalid fields: LEG_SECURITY_DESC (620) and LEG_SECURITY_ID (602)’>

This change is currently available for customer testing in New Release.

CME Globex Market Segment Gateway Enhancements - May 17

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.

Starting on Friday, February 28, 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 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, April 18 and Saturday, May 2, 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.

BrokerTec CME Globex New Release Environment Access

In preparation for the BrokerTec markets launch on CME Globex in Q4 2020, customers and vendors will need to begin to develop and test their applications via CME Globex New Release Environment. The New Release Environment supports products, messaging and functionality testing prior to production launch. Basic functionality for all APIs is currently available in the New Release Environment.

All BrokerTec customers will be required to establish connectivity to the CME Globex New Release Environment prior to testing. Customers may choose one of two ways to connect:

• CME Cert VPN - which uses a secure, encrypted tunnel through an Internet service that supports VPN protocols
• CME Cert Data Center - which allows customers to cross connect to CME Data Center locations where this option is offered, using a 1Gbps fiber handoff.

Internet access to the New Release environment for the CME STP and CME STP FIX APIs is also available now.

To request connectivity to the CME Globex New Release Environment for BrokerTec:

• BrokerTec customers who are new to CME Group must submit a Certification/New Release Environment Access Request and Change Form.  This form can be found on the BrokerTec Support Portal.
  • To access the BrokerTec Support Portal you must be an existing customer or vendor with a signed Non-Disclosure Agreement (NDA) in place with BrokerTec.  
• BrokerTec customers who already have a CME Cert VPN or CME Cert Data Center connection should contact their Global Account Manager to request that their existing connection be configured to connect to BrokerTec in the New Release Environment.

Learn more about how to get set up to test in the CME Globex New Release Environment:
