All TT customers who use STunnel must download the new zip file and apply it at any time before July 28, 2023. 

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

BIST: BISTECH 3.0

August 7

A new phase of the BISTECH system, called BISTECH 3.0, is announced to be launched by the exchange on August 7, 2023. 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 4 August 2023, 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 4 August.

On the go live date of 7 August, 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.

LME: TT User Setup Change to Direct Electronic Access (DEA) Field

TT has duplicate fields for DEA (Direct Electronic Access) in user setup for LME, one LME specific, and the second being the MiFID II DEA field. TT has copied values from the LME specific DEA field to the MiFID II DEA field. Removing the LME specific field will prevent customers from incorrectly populating values that need to be sent to the exchange, and will also match the normalized DEA field used for all other exchanges. Customers are encouraged to validate correct values in the MiFID DEA field. In the coming weeks TT will be removing the LME specific DEA field. For further information on this change, please contact onboarding@trade.tt.
