TTFIX.crt: Update Notice

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_GIFT: Full-scale Operation of NSE IFSC-SGX

July 3

SGX has announced that the full transition of SGX Nifty derivatives to NSE IFSC (SGX GIFT City) will be on July 3, 2023.

SGX GIFT City went live on July 29, 2022. Since that time, the NIFTY products have been trading in parallel on both the “SGX” (Titan) and the “SGX_GIFT” (GIFT City – NSE) platforms both on the exchange and on TT.

Starting from July 3, 2023 there will be a permanent shutdown of NIFTY trading on SGX Titan. From that time, all SGX users must trade the NIFTY on SGX_GIFT. The exchange will continue to support trading on the far months of the product on SGX Titan throughout the transition to aid Risk / Position management.

All of the above points apply to DMA trading only. Users sending Trade Report (NLT / Wholesale / OTC) orders will continue to use the SGX Titan platform even after the transition.

Please note that SODs and position tracking on the TT platform should be managed by customers as needed.

While trading of the SGX NIFTY will no longer be available via the SGX market, TT will continue to support trading of the SGX NIFTY product on the SGX_GIFT market. For customers who already have access to SGX_GIFT on TT, there are no specific steps that need to be taken on the TT platform to prepare. Any customers who are still trading SGX NIFTY via the SGX market and would like assistance in connecting to SGX_GIFT should contact their TT Onboarding or Sales representative.
