For those interested in investing or trading global stocks, understanding the operating hours of the U.S. stock market is crucial to avoid mistiming your positions. Given the significant time zone difference between Indonesia and the U.S., local investors need to adjust their schedules accordingly. This article provides a comprehensive overview of the U.S. stock market hours in Indonesia time, covering the NYSE and NASDAQ exchanges. This way, you can plan your strategies more effectively and not miss critical market moments.

When Does the U.S. Stock Market Open?

The U.S. stock market consists of two main exchanges: the New York Stock Exchange (NYSE) and Nasdaq. The operating hours of the NYSE (New York Stock Exchange) and NASDAQ are essentially the same, as both follow the standard U.S. stock market trading hours. While the structure and types of listed companies may differ, the trading hours for both exchanges remain identical.

Both exchanges open and close at the same times on each business day in local time. So, whether you’re trading on the NYSE or NASDAQ, you’ll need to adjust to the same hours in Indonesia’s time zone.

Daylight Saving Time (DST) and Its Impact

One important factor to consider is Daylight Saving Time (DST) in the United States. DST typically runs from March to November, during which the market’s operating hours shift one hour later compared to standard time. When DST is in effect, U.S. stock market hours are from 9:30 PM WIB to 4:00 AM WIB. When DST is not in effect, the hours revert to 8:30 PM WIB to 3:00 AM WIB.

3 U.S. Stock Market Trading Sessions

Trading Session	EST Hours	WIB Hours	Brief Description
Pre-Market Trading Hours	4:00 AM–9:30 AM EST	4:00 PM–9:30 PM WIB	Low volume, ideal for anticipating news or early reports.
Regular Trading Hours	9:30 AM–4:00 PM EST	9:30 PM–4:00 AM WIB	Main session, highly liquid, focus for most strategies.
After-Hours Trading	4:00 PM–8:00 PM EST	4:00 AM–8:00 AM WIB	Quieter activity, wider spreads, reactions to news.

The U.S. stock market has three main trading sessions each day that you need to know if you want to actively follow market movements. Each session has distinct characteristics and volatility levels, so understanding when liquidity is high or low is essential. These sessions are based on U.S. Eastern Standard Time (EST), but when converted to Indonesia Western Time (WIB), here’s the complete breakdown:

• Pre-Market Trading Hours
  The pre-market is the trading session before the official market opening. Trading volume is typically low, but sharp movements can occur if significant news or financial reports are released early. Many professional traders enter this session to take early positions or react to overnight global conditions. This session runs from 4:00 AM to 9:30 AM EST, or approximately 4:00 PM to 9:30 PM WIB.
• Regular Trading Hours
  This is where the majority of transactions occur, involving both retail and institutional investors. The highest volatility typically happens in the first and last hours, so many trading strategies focus on these times. This is the main trading session, running from 9:30 AM to 4:00 PM EST, or 9:30 PM to 4:00 AM WIB. The highest transaction volume usually occurs during this session, particularly in the first and last hours of trading.
• After-Hours Trading
  After the market closes, there’s an extended session used by some investors to respond to news or significant events outside regular hours. However, with fewer transactions, liquidity is lower, and the risk of sharp price movements with limited offers is higher. The after-hours session runs from 4:00 PM to 8:00 PM EST, or approximately 4:00 AM to 8:00 AM WIB.

Understanding these three sessions will help you determine the best times to enter or exit positions while avoiding risks associated with low liquidity outside the main trading hours.

When Does the U.S. Stock Market Close for Holidays?

The U.S. stock markets, such as the NYSE and NASDAQ, do not operate every business day throughout the year. There are specific days when the markets are fully closed, typically due to U.S. national holidays, including New Year’s Day, Independence Day, Thanksgiving, and Christmas Day. Additionally, there are days when the market operates for only half a day, such as the day before Christmas or Thanksgiving.

Besides national holidays, the U.S. stock market is also closed on Saturdays and Sundays. This means no trading activity occurs on these days, and all orders and price movements are paused. Therefore, it’s important to pay attention to the holiday and weekend calendar to plan your entry and exit strategies accurately. Market closures can also be a good time to evaluate your portfolio and prepare trading plans for the following week.

24-Hour U.S. Stock Trading Option on Reku

Now, investors from Indonesia can enjoy near-continuous access to the U.S. stock market thanks to Reku’s 24-Hour Trading feature. This feature combines four trading sessions—Overnight, Pre-Market, Regular, and After-Hours—running consecutively for five days a week, from Monday morning to Saturday morning Western Indonesia Time (WIB).

This flexibility allows you to adjust your trading schedule to your daily routine without being tied to the regular U.S. market hours. However, keep in mind that the U.S. applies Daylight Saving Time (DST), which affects the time conversion to WIB throughout the year.

What is Reku’s 24-Hour Trading and How Does It Work?

The 24-Hour Trading feature allows you to place orders outside the regular U.S. stock market hours. With this system, trading is not limited to the main exchange sessions (NYSE/NASDAQ) but extends to pre- and post-trading sessions. While the market appears “open all day,” it’s important to note that the types of orders permitted vary by session.
