While the changes to support these are deployed in both TT UAT and Prod, exchange has postponed the go live date for these products and hence, these are not currently available in TT UAT.

Nord Pool: Throttling Messages Unavailability

TBD

The Throttling messages received from Nord Pool are currently displayed as News messages on TT. On May 27, Nord Pool will change the endpoints from which these messages are obtained. TT will not be ready for this change on Day 1. TT’s readiness date will be communicated in subsequent System News. Till that time, these throttling messages will not be available on TT.

EEX : Support for FOK orders 

Q3 2026

EEX has added support for FOK orders on July 6. This functionality is available in the EEX simulation environment, and will be available in EEX production from July 6. 

For FOK orders, the SMP instructions Cancel Aggressive and Cancel Passive (default at EEX) are supported. However, as Cancel Both could lead to partial fulfilment, this instruction type is not supported for FOK. Any FOK order submitted with the Cancel Both instruction will therefore be rejected.

TT will not support this feature on launch, but availability is expected by the end of Q3 .

EEX Announcement

CME : Livestock Futures and Options Migration to New Market Segments and MDP Channels

Spetember 13

CME has postponed the Livestock product migration from August 16, 2026, to September 13, 2026. The products will move from the Agricultural complex to new MDP multicast channels and MSGW connectivity.

For MSGW order routing, clients will need new connections for Segment ID 71 (Futures and Spreads) and Segment ID 61 (Options and Strategies). TT will not support the new MSGW connections on the August 16 Day 1 go-live. Clients will need to use CGW connections to trade Livestock products until MSGW support is available

“GT” (Good Till Cancel, Good Till Date) Order Behavior

• For MSGW connections, CME will support the transition of resting GT orders to the new segments on their end, however, TT will not support this transition. Clients are therefore expected to cancel any resting GT orders for Livestock products on Segment IDs 60 and 70 by 4:00 PM CT on August 14. If GT orders are not canceled, clients will need to work directly with CME or use CME FirmSoft to manage those orders after the segment migration.
• For CGW connections, existing GT orders will continue to work and no action is required for the CGW connections.

Trading Schedule

• Livestock products will continue to follow CME’s standard 24×5 trading schedule.

• The below new order types will be introduced by MIAX –
  • Market to Limit
  • Iceberg / Reserve
  • Market with protection
  • Stop Market with protection
    • The planned date for adding support for the Market to Limit and Iceberg / Reserve order types is still being evaluated by TT, and may not be available Day1
    • TT does not plan to add support for the Market with protection and Stop market with protection order types
• MIAX will start disseminating settle prices on complex instruments, and hence the same will be available on TT.
• MIAX will send both active as well as inactive (i.e. instruments that have been added, but are not yet active) instruments in their reference data. TT does not plan to filter out any instruments based on the active / inactive status, as this will allow customers to configure any required limits before the instruments become active. The inactive instruments will have a status of Unknown on TT.

SGX : Launch of McCloskey FOB Australia Hard Coking Coal Futures

September 07

SGX has announced the introduction of the following future contracts

SGX McCloskey FOB Australia Hard Coking Coal Futures

Contract code : HCF

The Exchange will list up to 3 calendar years starting with the September 2026 contract, with 12 consecutive months added upon expiry in December.

Euronext: Changes introduced in SBE 366

September 28

Euronext will upgrade their API to a new version of SBE 366 on September 28. Below are the changes associated with this version upgrade –

• RFC Enhancements for Commodities
  • Euronext will start sending a book snapshot of the RFC responses over the market data feeds for the commodities market.
  • TT does not plan to support displaying the RFC book currently. But TT will make necessary changes to ensure the CLOB is not impacted due to the dissemination of the RFC book by Euronext. There will be no impact to any customer facing features due to these changes.
• Inactive Strategies on Commodities
  • Any strategy that does not have any open GTC/GTD order is currently marked as inactive by Euronext at end of trading. Such inactive strategies are not sent by Euronext in their reference data files. Before the start of trading on the next day, though, Euronext activates and sends all the exchange created strategies over the market data messages. Hence, the exchange created strategies that become inactive, disappear from TT for a few hours between the reception of the reference data files and reception of the market data messages.
  • With the SBE 366 release, Euronext will start sending all such inactive strategies on their reference data files. And hence, the exchange created strategies will not disappear from TT like they do today, unless these have expired / discontinued by Euronext.
  • In case of a user created strategy that gets inactivated in this manner, that too will be received on the reference data files, and hence will be available on TT. Since these will continue to stay inactive, no real time market data updates will be received on these and these will be displayed on TT with an Unknown status. In order to trade these strategies, these will need to be recreated using the Strategy Creation feature.
  • No changes are planned to be implemented on TT side for this.
• Change in Order price validation for RFC on Commodities
  • Currently, the order price validations applied to Request For Cross (RFC) on Derivatives instruments assess whether the price falls within both the Dynamic Collar of the Central Order Book (COB, EMM=1) and the Best Bid Offer (BBO).
  • With this enhancement, Euronext will replace the current RFC price validation mechanism for Commodity instruments, which relies on Dynamic Collars and the BBO, with a new price validation logic based on the Dynamic Collars and the instrument’s daily high and low prices, instead of the current best bid and offer (BBO) prices.
  • No changes are required on TT side for this. TT will display an error code of 2644, as sent by Euronext, for any RFC orders that get rejected by Euronext due to these price validations.

Euronext will upgrade their test environment with this new version on 15 July. Hence, TT recommends customers to test and verify for any impact to their processes post this date.

From 2026-09-30 these contracts will be migrated to their own separate market data channels. The Athex specific channels will be supported on TT from April 2027, and hence these contracts will not be available in TT UAT from 2026-09-30 to Mar 2027.

Stunnel Changes: Removing Certificate Pinning 

October 2026

As of Q2 2026 TT no longer provides / updates the stunnel.zip file which customers might be using to perform certificate pinning. The final certificate in the stunnel.zip file expires on Oct 17, 2026.  

Only customers who download the stunnel.zip file from https://library.tradingtechnologies.com/tt-fix/general/stunnel.zip are impacted. Affected customers should start migrating to utilize their local machine’s certificate trust store. Digicert and AWS are both established Certificate Authorities and should be available in the trust stores of modern operating systems. 

What This Means 

• Clients no longer need to download TTFIX.crt file 
• Clients configure stunnel to use their OS trust store path for CA validation 
• We verify the correct authentication chain rather than a single pinned leaf certificate 

Configuration Changes 

Previous (pinned certificate) 

[orfix-tcp]  

client = yes  

accept = 127.0.0.1:11702  

connect = FullyQualifiedDomainName:port  

CAfile = TTFIX.crt  

verify = 3 

New (OS trust store with chain validation) 

[orfix-tcp]  

client = yes  

accept = 127.0.0.1:11702  

connect = FullyQualifiedDomainName:port  

verifyChain = yes  

CAfile = <OS_SPECIFIC_TRUST_STORE_PATH> 

Notes and Additional Guidance 

• The snippet above is a single section of the client configuration.  For the other sections please see our online documentation here 
• Stunnel versions: verifyChain = yes is broadly compatible. If required, verify = 2 provides comparable chain validation. 
• For clients that currently connect to TT FIX using stunnel, we ask that they come into the UAT to test their needed configuration changes.
