SGX to launch ‘next-gen’ trading engine in second half of 2027

SGX Regulation is seeking public feedback on rule amendments and new functions of the engine from Thursday to Dec 31

With investor participation on the rise, the Singapore Exchange (SGX) Group will roll out a new trading engine for the local stock market in the second half of 2027, offering its members “better and additional” services, the group said on Thursday (Nov 6).

The new trading engine, called Iris-ST, will offer features ranging from new order types and risk controls, to more intuitive counter codes, said Ng Yao Loong, the head of equities at SGX Group.

“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,” added Ng.

SGX Regulation (RegCo) is seeking feedback from the public on rule amendments and new functions of the “Iris-ST” trading engine from Thursday until Dec 31.

Some of these proposals include removing the prefix and suffix from counter trading names – such as the ^ symbol for the financial watch list – for a better presentation of their names.

SGX RegCo also plans to extend the duration of the non-cancel phase of the auction routine, where there can be no order entry, amendment or withdrawal. The equilibrium price of orders is also determined during this non-cancel phase.

The revision to the phase will allow for more “good-faith orders” that cannot be amended or withdrawn to be entered just before orders are matched. This will benefit the robustness of the equilibrium price, said SGX.

The consultation paper is available for viewing on SGX’s website.
