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

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.

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.

UpdateUpdate - Mandatory iLink 3 Binary Order Entry Protocol for MSGW - Available Now in New Release

† Denotes update to the article

Starting Sunday, March 29 (trade date Monday, March 30), CME Group will launch iLink 3, a new order entry protocol for trading futures, options, and BrokerTec products on CME Globex, over 4 launch weekends. All customers connected via Market Segment Gateway (MSGW) will need to migrate to the iLink 3 by Q4 2020.

iLink 3 includes:

• Simple Binary Encoding (SBE);delivers faster encoding/decoding
• FIX Performance (FIXP) protocol; very simple, lightweight, point-to-point session layer
• More efficient iLink FIX messaging
• Standard message size, fixed positions, and fixed length fields
• Consistent encoding method for order entry and market data

iLink 3 will only support iLink MSGW sessions. The Client Impact Assessment is available and provides detailed functionality and messaging information.

†iLink 3 Binary Order Entry Update:

During the iLink 2 to 3 session migration, any MSGW sessions configured for iLink 3 must send iLink 3 messages if market segments are migrated to iLink 3, and send iLink 2 messages if market segments have not yet migrated to iLink 3.  A new MSGW config.xml file with a flag to indicate for each MSGW if it is enabled for iLink 3 is now available for customer download from CME Group SFTP site.

When iLink 2 sessions migrate to iLink 3 sessions, Good ‘Till Cancel (GTC) and Good ‘Till Date (GTD) orders on the migrated market segments will reflect the following messaging changes:

• CME Globex will return the Party Details Definition Request Acknowledgment message with tag 1505-PartyDetailsListRequestID=0 before everyEx ecution Report - Confirmation/Acknowledgment (tag 35 - MsgType=8)
• For iLink 3 Application messages from CME Globex to Client System,
  • tag 2422-OrderRequestID will be set to 0
  • tag 9537-Location will contain the truncated 5 bytes from the left of iLink 2 tag 142-SenderLocationID from the GT order
  • tag 527-SecondaryExecId and tag 1506-SideTradeID will contain Trade Number on tag 17-ExecID, except the spread leg trade execution. To enable client systems to link the spread instrument with each component leg, Execution Report - Trade Spread Leg will contain the same tag 527 value as  Execution Report - Trade Spread

For example, a calendar spread trade: 6BM7-6BJ7

iLink 3 Execution Report -Trade	Tag 17	Tag 527- SecondaryExecId	Tag 1506- SideTradeID
Spread: 6BM7-6BJ7	5081:M:45601TN0000007	7	7
Spread Leg 1: 6BM7	5081:M:45601TN0000014	7	14
Spread Leg 2: 6BJ7	5081:M:45601TN0000025	7	25

• The following iLink 2 tags will be deprecated and will not be present on iLink 3 outbound messages
  • tag 20-ExecTransType
  • tag 41-OrigClOrdID
  • tag-50-SenderSubID contains Market Segment ID.
  • tag 55-Symbol
  • tag 107-SecurityDesc
  • tag 167-SecurityType
  • tag 819-AveragePriceIndicator
  • tag 1731-AveragePriceGroupID
  • tag 9717- CorrelationClOrdID

To facilitate these GTC and GTD changes, customers can choose one of the following options by the close on Friday before each production launch weekend

• Leave all GTC and GTD orders as-is; any remaining GTC and GTDorders will reflect the above messaging changes
• Cancel all GTC and GTD orders for the affected products
• Modify GTC and GTD orders without changing the below parameters to prevent the order to lose priority in the book
  • Account
  • Increase quantity
  • Order type
  • Price
  • Stop trigger price
  • Minimum fill quantity

All client systems must complete the full certification before migrating to iLink 3 in production.

• All iLink 3 tests except the iLink 3 Failover Tests –  Available Now
• iLink 3 Failover Tests – Monday, March 23, 2020

NewNew - Update on Order Routing and Front-End Audit Trail Requirements for iLink 3

As noted in the CME Globex Notice on January 30, 2020, the required audit trail specifications in the Client Systems Wiki were amended in connection with the implementation of iLink 3.

Customer systems will not need to be certified for Audit Trail for iLink 3 prior to going to the production environment. Instead, all customer systems must capture and maintain the audit trail in raw format and have the ability to produce such audit trail in FIX format upon request until AutoCert+ for Audit Trail is available. Once AutoCert+ Audit Trail for iLink 3 is available, entities that connect an order routing or front-end system to the CME Globex platform through the iLink 3 gateway will be required to certify.

For additional information, please review the Market Regulation Advisory Notice on order routing and front-end audit trail regulatory requirements.

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.

The CME Globex MSGW enhancements are currently 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.
