What Are the 24-Hour Market Operating Hours?
The 24-Hour Market runs around the clock on weekdays, from Monday 08:00 WIB through to Saturday 08:00 WIB in standard time, shifting one hour earlier to Monday 07:00 WIB through Saturday 07:00 WIB during US Daylight Saving Time. It does not operate on weekends or on US exchange holidays. Inside that weekly window, each trading day divides into four consecutive sessions: Overnight from 08:00 to 16:00 WIB, Pre-Market from 16:00 to 21:30 WIB, Regular Market from 21:30 to 04:00 WIB, and Post-Market from 04:00 to 08:00 WIB, each shifting an hour earlier under DST. Orders placed through the 24-Hour Market are DAY orders, so they remain open until the next trading day: an order placed on Monday at 08:00 WIB is held until Tuesday at 08:00 WIB.

Q: When does Daylight Saving Time change these hours?
US Daylight Saving Time runs from the second week of March to the first week of November, and while it is in effect every session shifts one hour earlier in WIB terms. The Regular Market session moves from 21:30–04:00 WIB to 20:30–03:00 WIB, and the weekly window starts and ends at 07:00 WIB rather than 08:00 WIB.
Q: How long does an order placed in the 24-Hour Market stay open?
Until the end of the session cycle, because every 24-Hour Market order is classified as a DAY order. If it has not executed by 08:00 WIB the next trading day, or 07:00 WIB during Daylight Saving Time, it is cancelled automatically as expired and any reserved balance is returned. There is no GTC option available in the extended sessions at all.
Q: Which sessions accept which order types?
The three extended sessions — Overnight, Pre-Market, and Post-Market — accept Limit Orders only, always with DAY validity. The Regular Market session in the middle accepts Market, Limit, Stop, and Stop-Limit Orders with either DAY or GTC validity, exactly as on any ordinary trading day, because it is quite literally the ordinary trading day sitting inside the wider weekly 24-Hour Market window.
Q: Does the 24-Hour Market run at weekends?
No. The weekly window closes at Saturday 08:00 WIB and does not reopen until Monday 08:00 WIB, with both times shifting an hour earlier during Daylight Saving Time. US exchange holidays are treated the same way: no session runs on those days at all, including the Overnight session that would otherwise start the cycle for that trading day.
