If you’re a Malaysian retail investor trading US stocks through M+ Global, understanding when the US market opens and closes in your local time is essential for planning your trades, setting alerts, and avoiding costly mistakes. This guide breaks down all three trading sessions and upcoming market holidays.
Regular Trading Session
The regular trading session is when the vast majority of US stock trading happens. This is when you’ll see the tightest bid-ask spreads, highest liquidity, and most reliable price discovery.
The regular session runs 9:30–16:00 Eastern Time (ET), Monday to Friday.
In Malaysia time, this converts to:
- Daylight Saving Time (March–November): 21:30–4:00 Kuala Lumpur Time
- Winter Time (November–March of the following year): 22:30–5:00 Kuala Lumpur Time
Remisier tip: Mark your calendar when US daylight saving changes in March and November—your trading window shifts by one hour. Set phone reminders if you’re a swing trader, as missing the opening or closing bell can affect your strategy.
Pre-Market and Post-Market Trading Sessions
Beyond the regular session, the US markets offer extended trading hours through pre-market and post-market sessions. These allow you to trade before the official open and after the official close, but with important caveats: lower volume, wider spreads, and higher volatility.
| Session | Eastern Standard Time | Daylight Saving Time (March–November) Kuala Lumpur Time |
Winter Time (November–March) Kuala Lumpur Time |
| Pre-market | 4:00–9:30 | 16:00–21:30 | 17:00–22:30 |
| Post-market | 16:00–20:00 | 4:00–8:00 | 5:00–9:00 |
Pre-market session starts as early as 4:00 AM ET and runs until the regular open at 9:30 AM ET. In Malaysia, that’s 16:00–21:30 (March–November) or 17:00–22:30 (November–March). This session is popular for trading on overnight news and earnings announcements from Asia.
Post-market session runs from 4:00 PM to 8:00 PM ET (or 5:00 PM to 9:00 PM in winter). In Malaysia, that’s 4:00–8:00 (March–November) or 5:00–9:00 (November–March). This is when US companies often release earnings reports and major news, creating trading opportunities for alert investors.
Remisier tip: Extended hours are real, but liquidity is much lower. If you’re new to US stocks, stick to the regular session (21:30–4:00 or 22:30–5:00 KL time) until you’re comfortable with market mechanics. Avoid placing large orders in pre-market or post-market unless you have specific news-driven reasons.
US Stock Market Holidays
The New York Stock Exchange (NYSE) and Nasdaq close on 10 designated US holidays per year. On these days, you cannot trade US stocks at all—not even in pre-market or post-market sessions.
The 10 regular US market holidays are:
- New Year’s Day
- Martin Luther King Jr. Day
- President’s Day
- Good Friday
- Memorial Day
- Juneteenth National Independence Day
- Independence Day
- Labor Day
- Thanksgiving Day
- Christmas Day
Holiday rule: If a holiday falls on a Saturday, the exchange closes on Friday. If it falls on a Sunday, the exchange closes on the following Monday.
Some holidays also include early closes. For example, the day before Independence Day and the day after Thanksgiving both close at 1:00 PM ET (3 hours early).
M+ Global will notify you of market closures in advance, but it’s always wise to check the NYSE holiday calendar before placing orders on unfamiliar dates.
Remisier tip: Plan your trading around holidays—don’t be caught holding a position you wanted to exit if the market is closed the next day. This is especially important during the November–December holiday season.
Key Takeaways
- Regular US stock trading runs 21:30–4:00 KL time (March–November) or 22:30–5:00 KL time (November–March).
- Pre-market trading starts at 16:00 or 17:00 KL time; post-market extends to 8:00 or 9:00 KL time, but with lower liquidity.
- US daylight saving changes in March and November shift your trading window by one hour.
- The NYSE closes fully on 10 designated holidays yearly; check in advance if you’re unsure about a trading date.
- Extended hours (pre and post-market) are real but riskier—beginners should trade during the regular session.
- M+ Global will alert you to market closures, but maintaining your own holiday checklist prevents costly mistakes.
Frequently Asked Questions
What time does the US stock market open in Malaysia time?
The regular session opens at 9:30 AM ET, which is 21:30 (March–November) or 22:30 (November–March) in Kuala Lumpur time. Pre-market trading begins even earlier, at 16:00 or 17:00 KL time.
Can I trade US stocks on US holidays?
No. The NYSE and Nasdaq are fully closed on the 10 designated US holidays. You cannot trade during regular, pre-market, or post-market sessions on these days. M+ Global will notify you in advance of all closures.
Why do my US trading hours change twice a year?
The US observes daylight saving time from March to November, shifting Eastern Time one hour ahead. Malaysia does not observe daylight saving, so the time difference between KL and ET changes twice yearly, shifting your local trading window by one hour.
Should I trade during pre-market or post-market sessions?
Only if you have a specific reason (e.g., trading on overnight news). These sessions have much lower liquidity and wider bid-ask spreads than the regular session. Beginners should trade during regular hours (21:30–4:00 or 22:30–5:00 KL time) for better execution.
Does M+ Global trade during all US market hours?
Yes, M+ Global supports trading during regular, pre-market, and post-market sessions. However, the same US holiday closures apply—the market is closed on designated holidays, and M+ Global will notify you in advance.
