Trading hours and call auctions

The KRX regular session runs 09:00–15:30 KST, with call auctions at the open and the close.
Also known as: Regular session, single-price auction

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, stocks can trade from 8:00 a.m. and until 8:00 p.m., and since September 14, 2026 the Korea Exchange itself runs a real-time after-hours market from 4:00 to 8:00 p.m. KST. Check which venue your broker routes orders to; the Korea market holidays page converts these hours to New York, London and Singapore time.
