CME: Mandatory Migration to iLink 3.0 – Available in Production

March 1

Summary: CME has introduced support for iLink3 on Convenience Gateways (CGW) for trading futures and options on CME Globex. CME will decommission CGW iLink2 on April 6, 2025 however, all customers must migrate by March 1, 2025 to avoid penalties.

NOTE: As of March 1, CME will charge customers $1000 per week for the continued use of iLink 2 credentials.

Convenience Gateway Migration from iLink 2.0 to iLink 3.0: Customers familiar with the MSGW iLink3 upgrade that occurred in 2019 will find the CGW iLink upgrade familiar. The steps for migrating are as follows:

1. Coordinate with CME to apply for an iLink3 Convenience Gateway Session.
   1. When applying for a new iLink3 Session, Members should specify TT frontend name “TT CME iLink3 CGW”
2. For each iLink Session, create NEW Connections in Setup
   1. Be sure to use a Session ID created by CME specifically for iLink3 (see #1 above).
   2. Be sure to set the Connection Type to “Convenience Gateway iLink3.”
   3. PLEASE NOTE: Modifying an existing connection’s “Type” (for example, changing a connection from “Convenience Gateway” to “Convenience Gateway iLink3” is not supported. All customers migrating from iLink2 to iLink3 must create a new connection for iLink3.
3. FIX configurations, Order Tag Defaults, etc. will all continue to function with no changes required since the functionality of TT CGW iLink3 is identical to TT MSGW iLink3.
4. Throttle Limits
   1. For on-demand order entry, TT recommends that customers set their Connection level Max Order Rate to 250 transactions per second in order to ensure CME iLink session throttle limits are not exceeded.
   2. This limit will be applied to New Order Single and Change messages, but Cancel messages will not be throttled by TT.
      1. Note: Cancel messages are accounted for in the rolling transaction per second queue, but will not be rejected by TT.

Access to Testing: The Convenience Gateway for iLink 3.0 on-demand order entry is available now for testing in UAT. Members who have not yet started verifying iLink 3.0 are strongly encouraged to begin testing as soon as possible.

Access to Production: The Convenience Gateway for iLink 3.0 OnDemand order routing is available now for Production trading. Members are welcome to begin migrating as desired. User acceptance testing prior to migration is highly recommended.

Please note: GTC orders will not persist when moving from an iLink 2 connection to an iLink 3 connection. TT recommends that, where possible, customers place GTC orders via iLink 3 sessions as they prepare to fully migrate to iLink 3.

UPDATE: Production Support for CME iLink 3.0 Pre-registration

Support for pre-registration on CME iLink 3.0 is available now in Production. This version of the TT CME iLink3 Gateway will continue to support “On Demand” order entry and will also support the CME iLink3 “Pre-Registration” order entry type, allowing orders to be submitted to the exchange using a single order message alone.

For additional information, please refer to the documentation:

Documentation/ iLink3 Migration Guide: The TT CME iLink3 Migration Guide is now available at the link below. 

Pre-Registration vs On-Demand Order Support: At this time, TT support of CME iLink 3.0 is limited to on-demand orders only. However, TT engineers are currently working to complete support for the exchange’s new “pre-registration” order entry method. Details about TT handling of pre-registration, including implementation details, Max Order Rate settings and delivery schedules, are provided in the iLink3 Migration Guide.

Further updates regarding timelines, migration, documentation, etc will be shared here in System Admin News & Updates.

MEFF: Launch of European-style Stock Options with Cash settlement

March 3

From March 3, 2025, MEFF will launch European-style Stock Options with Cash settlement. In the initial phase, these contracts will be launched on the below symbols –

• BBVA
• IBE
• ITX
• SAN
• TEF
• REP

In order to differentiate the cash settled options from the existing physically settled ones, the Delivery Type (Physical / Cash) will be added to the Alias / Display Name of the option contracts on TT.

B3: Binary Protocol

B3 has introduced new lower-latency binary protocols for market data via the Unified Market Data Feed (UMDF) and order entry via Simple Binary Encoding (SBE). 

On March 19, 2024, TT upgraded the B3 binary market data protocol in UAT; the release note can be found here: https://library.tradingtechnologies.com/release_notes/uat-2024-03.html

Please note that on the new binary SBE UMDF market data protocol, B3 does not send Settle and SettlePU prices. B3 plans to address this in Q2, with the solution becoming available to ISVs in Q3. To address this in the new protocol, TT is implementing an interim solution to retrieve Settle and SettlePU from the old protocol at the beginning and end of each trading session. These values will remain constant until the end of the trading session and won’t be updated in real time. Once this feature becomes available via the new protocol, these values will once again be updated in real time.

Please note that B3 continues to support the legacy protocols in parallel with the new Binary offering and the TT migration will follow a phased approach:

• Phase 1: TT will update its Market Data feed to use the new UMDF protocol, which is compatible with both the new SBE Order API and the legacy order entry protocol – no changes are expected for end users. This is completed and available in UAT.
• Phase 2: TT will allow customers to continue using their existing order connections, and in parallel will allow customers to configure and use new connections using SBE. 
• Phase 3: TT will discontinue support of the legacy orders API, and customers will need to utilize new SBE connections. Please note that any GTC/GTDate orders on legacy connections will be canceled when we cut off support for the old API.

B3 has set the length of Entering Trader trader to five.

The following are the anticipated milestones for this project:

ASX: Bond futures Delinking and Tick Change Testing

KRX: Night Session

June 9

In June, KRX will introduce support for Night Session trading on a limited set of products.

The session time for the night session will be from 1800 to 0600 KST and will be held from Monday to Friday. The trades done on this night session will have a trade date of T+1 i.e. of the next business day. So, the trades done on Monday night session will have Tuesday’s date as the trade date. The trades done on Friday night session will have Monday’s date as the trade date.

Although these products will be traded during both the Day and Night sessions, and will have the same ISIN / Security Id, KRX will treat the Day and Night sessions as two separate order books, i.e., two separate instruments. Therefore, these will be maintained as two separate instruments in TT under 2 different product symbols. The night session symbols will have an ‘N’ appended to them.

Trading Firms connecting to KRX through TT are advised to reach out to their brokers to determine any required changes on their venues. TT will also be reaching out to KRX FCMs to agree on an approach for their venue. 

TT plans to participate in the dress rehearsal scheduled by the exchange on May 17. Customers are advised to participate in this test, as participation in the dress rehearsals is mandated by the exchange.
