Regular session
The Korea Exchange regular session runs on weekdays from 9:00 a.m. to 3:30 p.m. Korea time. Orders are matched continuously as soon as prices meet.
Call auctions
From 08:30 to 09:00 and from 15:20 to 15:30, orders are collected and executed at a single price that maximizes traded volume. The closing auction sets the official closing price.
What to keep in mind
Since the alternative exchange Nextrade opened in March 2025, some stocks can also trade before and after the regular KRX session. Check which venue your broker routes orders to.
