HKEX: Introduction of new contracts on Partition 3

TBD 

HKEX will introduce new futures and options (both monthly and weekly) options contracts on new product symbols VAA and VBB. The market data for these will be obtained from a new partition (partition 3) which will be added by HKEX.

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 

HKEX: OAPI RHEL library upgrade and recertification

September 22, 2026

HKEX has announced an upgrade to its OAPI library from RHEL7 to RHEL8. The deadline for completion of this upgrade is 2026-09-22, post which any softwares that are still on RHEL7 will lose access to HKEX.

TT will facilitate customer participation in upcoming exchange practice sessions, which are optional, however customers are required by the exchange to submit a declaration of readiness. Customers can request TT service teams for the signed declaration form from TT.

TT participated in the practice session conducted on 11 Aug, and has successfully passed the certification. These changes are now available in the TT UAT environment, and are planned to be deployed to Prod by September 18.

MIAX plans to launch TAS futures and Cross Product Spreads on commodities on September 27. T plans to support it from Day1, and these will be under the MIAX_FUT_CH market on TT.

These are expected to be available in TT UAT from September 18.

MIAX also plans to launch BTIC futures and Cross Product Spreads on financial futures (which is the MIAX_FUT_NY on TT), but the date for this is not yet confirmed, and will be later in Q4 2026.

MIAX: New Order Types, and Settle price on complex instruments

September 27

MIAX plans to introduce the below changes on September 27. These will be applicable only for commodities, which is the MIAX_FUT_CH market on TT.

• 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.

TT will not be supporting these products from Day 1 , and will look to add support for these products by end of September 2026 .

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.

Stunnel Changes: Removing Certificate Pinning 

Prod-Live: September 25

Beginning in Q2, 2026, TT will no longer provide or update the stunnel.zip file which customers had previously used to perform certificate pinning. The final certificate in the stunnel.zip file will expire on Oct 17, 2026.   

Customers who previously download the stunnel.zip file from https://library.tradingtechnologies.com/tt-fix/general/stunnel.zip should migrate to their local machine’s certificate trust store as soon as possible. Digicert and AWS are both established Certificate Authorities and are available in the trust stores of modern operating systems.  

Important Dates: 

UAT: 

• September 22: The Digicert certificate has been replaced with an AWS certificate, which is not included in the stunnel.zip  
• As of that date, customers who utilize the UAT environment are required to have AWS in their trust store 

Prod-Sim: 

• As early as September 23, completed by September 24: The Digicert certificate will be replaced with an AWS certificate, which is not included in the stunnel.zip 
• As of that date, customers who utilize the UAT environment are required to have AWS in their trust store 

Prod-Live: 

• Cutoff Dates by location 
• September 25: NY Datacenter 
• October 2: All Remaining Datacenters 
• The Digicert certificate will be replaced with an AWS certificate, which is not included in the stunnel.zip 
• As of that date, customers who utilize the Prod environment are required to have AWS in their trust store. 

Please note: 

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

Required Configuration Changes  

Previously Supported Configuration (pinned certificate)  

[orfix-tcp]   

client = yes   

accept = 127.0.0.1:11702   

connect = FullyQualifiedDomainName:port   

CAfile = TTFIX.crt   

verify = 3   

New Required Configuration (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 shows one section of the client configuration. For the other sections, see the online documentation here. 
• Stunnel versions: verifyChain = yes is broadly compatible. If required, verify = 2 provides comparable chain validation.  
• Customers currently connecting to TT FIX through stunnel should test the required configuration changes in UAT before migrating to production. 

For Window Users  

Windows maintains trust certificates in the Windows trust store. To allow stunnel/OpenSSL to use Windows-managed trust rather than a separate PEM CA bundle, customers need an integration mechanism such as the OpenSSL CNG provider (cngprov.dll), available at https://www.stunnel.org/cng-downloads.html.

After downloading cngprov.dll from the stunnel site, place it in C:\Program Files (x86)\stunnel\ossl-modules.  Then update the stunnel configuration using the sample below. 

For Stunnel versions 5.75 or greater, the configuration is as follows:  

; — GLOBAL SECTION —

1. 1. cngprov provides access to the Windows trust store ##
      provider = cngprov

; — SESSION LEVEL —

[orfix-tcp]

client = yes

accept = 127.0.0.1:11502

connect = FullyQualifiedDomainName:port

verifyChain = yes

1. 1. The Local Machine Root store is used as the trust source ## 
      CAstore = cng:store_name=Root;store_location=LocalMachine 

For Stunnel versions earlier than 5.75  the config below will only be needed: 

; — SESSION LEVEL —

The following OS-specific trust store paths were gathered from publicly available sources. Customers should confirm the correct path with their internal IT teams before updating the stunnel configuration. 

OS-Specific Trust Store Paths 

• Ubuntu / Debian / Linux Mint: CAfile = /etc/ssl/certs/ca-certificates.crt 
• Red Hat (RHEL) / CentOS / Fedora / Amazon Linux: CAfile = /etc/pki/tls/certs/ca-bundle.crt 
• Alpine Linux: CAfile = /etc/ssl/cert.pem 
• SUSE / openSUSE: CAfile = /etc/ssl/ca-bundle.pem 
• Windows: Windows does not expose a single PEM of system roots. The stunnel installer provides a bundled root file. Use CAfile = ca-certs.pem (located in the stunnel installation directory). 
• macOS 
• Intel: CAfile = /usr/local/etc/openssl/cert.pem 
• Apple Silicon: CAfile = /opt/homebrew/etc/openssl/cert.pem
