Iris-ST will enable SGX Member firms to offer better and additional services, equipping them to seize opportunities as the market grows. To enable the full suite of services Iris-ST makes possible, Singapore Exchange Regulation (SGX RegCo) is seeking feedback on rule amendments for enhancements and new functionalities which include the following: 1) new auction price collars, 2) extension of the non-cancel phase during auction routines and revisions to allow order entry (but not order amendment or withdrawal) during this phase, 3) 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. With the new PTRC system, the exchange-hosted error prevention mechanism, the Forced Order Range and “Force Key” function, will be removed … … The consultation is open till 31 December 2025 and is found here. SGX Group expects Iris-ST to begin running in the latter half of 2027.”
