ICE: API Upgrade

Q3 2023

ICE has scheduled deployments for late August 2023, which involve a few API enhancements. TT is currently reviewing these changes and will implement any required changes accordingly.

TTFIX.crt: Update Notice

June 23 – August 12

For customers whose FIX engine natively supports SSL encryption, or who have implemented FIX session encryption using STunnel, TT provides a TTFIX.crt file with the public certificates used by the TT platform FIX endpoint.

On June 22, 2023, TT updated the file located in the TT Help Library in order to update the soon-to-be-expired certs in the TTFIX.crt bundle.

All TT customers who use STunnel must download the new zip file and apply it at any time before August 12, 2023. Please note that the old certificates expire on August 12.

Added TT Platform STAR.TRADE.TT; valid from June 16, 2023 – June 15, 2024 (DC)

Additional Resources

Please download the updated here. Directions for configuring a stunnel with TTFIX.crt can be found on the TT FIX Help Site.


New date TBD

A new phase of the BISTECH system, called BISTECH 3.0, is announced to be launched by the exchange. The go live date for this, which was earlier planned for 12th June, has been pushed back by the exchange, and details on the new release date are awaited.

As part of this upgrade, the TT platform will support the connection changes required for the FIX Order Entry and TIP channels in the derivatives markets.

Equity Markets, Fixed Income Markets, Precious Metals Markets, exchange’s Drop Copy functionality and ITCH protocol for market data are not supported by the TT platform currently, and hence the TT platform will be unaffected by any changes to these.

On the last business day before the go live date, in preparation for the transition to BISTECH 3.0, there will be no evening session in the Derivatives market and all GTC, GTD and inactive Stop orders waiting in the system will be deleted by the exchange, and these will not be reinstated post the cutover. Hence, TT recommends that traders cancel such orders on or before this date.

On the go live date, company admins will need to update the order entry connection settings with the latest user details that they may have received from the exchange, in order to be able to enter orders post this change.

SGX will be conducting maintenance activity on SGX Gift ICI Data Center on July 08 2023, Saturday, between 1500 to 1900 hours SGT.During this time,  GIFT SGX-ICI services will be impacted.

The change related to the revision of expiry of Futures and Options contracts for Nifty Bank (BANKNIFTY) has been canceled by the exchange. So, there will not be any change to the expiry of these contracts and these will continue to expire on Thursdays.

BIST: BISTECH 3.0 Dress Rehearsal 2

July 8

TT plans to participate in the Dress Rehearsal for the BISTECH 3.0 scheduled by the exchange for 8 July, 2023. This Dress Rehearsal will be conducted in the TT Production Environment on the said date. For this test, all BIST systems will open as a normal working day on Saturday morning, but the normal trading session will close at 3:40 PM Turkey Time and no order entry will be allowed after this time. This dress rehearsal will also involve a failover scenario, and the BIST primary servers will be made unavailable any time post 1 PM Turkey time. Post this failover, TT will connect to the BIST secondary servers for the reminder of the day.

Company admins will need to update the order entry connection settings with the latest user details that they may have received from the exchange for this test.
