Do you mean traders set up buy or sell orders and they get matched when market opens? That's... Just how markets work normally?

Yes and no. There's a distinct auction that runs and it is a distinct event and has its own rules. Eg 5 mins (idr exactly, it's been 6 years for me) before the opening cross you can no longer cancel auction orders, post-only. At the open, they run an opening match of all the auction orders, THEN normal trading begins.
