Singapore Exchange Group (SGX) is introducing a new trading engine called Iris-ST for members to offer better services, and is seeking feedback.

The Iris-ST is meant to enable member firms of the SGX to offer better and additional services, and equip them to seize opportunities as the market grows. These “new and improved” features range from new order types and risk controls, to more intuitive counter codes.

“The level of investor participation is increasing, and our product shelf is expanding. This is the right time to implement a next-gen trading infrastructure that will meet new and emerging demands,” said Ng Yao Loong, head of equities, SGX Group.

The Singapore Exchange Regulation (SGX RegCo) is seeking feedback on rule amendments for enhancements and new functionalities relating to Iris-ST.

These feedback includes new auction price collars; extension of the non-cancel phase during auction routines and revisions to allow order entry; and a new pre-trade risk control (PTRC) system that SGX Member firms may use to meet their obligations to have adequate pre-execution risk management control checks and error prevention alerts.

The consultation is open until Dec 31, 2025, and the SGX Group expects Iris-ST to begin running in the second half of 2027.
