IDX operates Monday through Friday, opening at 09:00 and closing at 16:00 local time (Asia/Jakarta). A lunch break occurs from 11:30 to 13:30.
For investors in Seoul, this means the IDX market opens at approximately 18:00 Korea Time and closes around 01:00 Korea Time.
The regular trading session is the most important period, but pre-market and after-hours sessions also provide opportunities for traders who need to react to news outside regular hours.
