Forex markets operate 24 hours a day, five days a week, because trading moves across time zones as each major financial center opens and closes

The foreign exchange market has no single physical location. Instead, it is a network of banks, brokers, and traders spread across the globe. When it is 9 a.m. in New York, it is already evening in Tokyo and early morning in London. Because of this, currency pairs are always being traded somewhere, and the market never truly closes — except on weekends.

Trading volume and volatility change throughout the day as different regions wake up and start their business. The busiest times are when two major sessions overlap, such as when London opens while New York is still active. Understanding when these sessions run helps you know when to expect the most price movement and liquidity in the pairs you want to trade.

Key Takeaways

  • The forex market runs Sunday evening through Friday evening in U.S. Eastern Time, with no trading on weekends.
  • Four major trading sessions — Tokyo, London, New York, and Sydney — each bring different trading volume and price movement patterns.
  • The overlap between London and New York (roughly 8 a.m. to noon Eastern Time) is typically the most active period for currency trading.
  • Currency pairs move at different speeds depending on which session is active, so the best time to trade depends on which pair you are watching.

The Four Major Trading Sessions and Their Hours

The forex market is divided into four overlapping sessions, each centered on a major financial hub. The Tokyo session (also called the Asian session) runs from roughly 7 p.m. to 4 a.m. Eastern Time. The London session opens at 3 a.m. Eastern Time and closes at noon. The New York session runs from 8 a.m. to 5 p.m. Eastern Time. The Sydney session (also called the Oceania session) starts at 5 p.m. Eastern Time and ends at 2 a.m. the next morning.

These times shift by one hour when daylight saving time changes, because not all regions observe it on the same dates. The U.S. typically switches in mid-March and early November, while Europe switches on different dates, and some regions do not observe daylight saving at all. Your broker's platform should display times in your local zone, but it is worth checking whether the hours listed account for daylight saving in your location.

The sessions overlap in specific windows. London and Tokyo overlap from 3 a.m. to 4 a.m. Eastern Time. London and New York overlap from 8 a.m. to noon Eastern Time. Sydney and Tokyo overlap from 7 p.m. to 2 a.m. Eastern Time. These overlaps are when two major markets are active at once, which typically brings higher trading volume and tighter bid-ask spreads.

Why Volume and Volatility Change by Session

Each session brings its own set of traders, news releases, and economic data. During the Tokyo session, Japanese economic reports and Asian stock market movements drive currency pairs involving the yen. During the London session, European economic data and the pound sterling dominate. The New York session sees U.S. economic reports, Federal Reserve announcements, and stock market activity move the dollar and other pairs.

Volatility is highest during overlaps because two major markets are pricing in information at the same time. The London-New York overlap is the most active period of the entire week for most currency pairs. During slow sessions — such as early Tokyo or late Sydney — spreads widen and price movement slows, which can make it harder to enter and exit trades at the prices you want.

How to Find Exact Opening Times for Your Broker

Your broker's trading platform displays session times, but they may show them in your local time zone or in a different reference time. Most platforms have a settings menu where you can choose which time zone to display. If your broker shows times in UTC (Coordinated Universal Time, also called GMT or Greenwich Mean Time), you can convert them to your local time by adding or subtracting hours based on your location.

Some brokers publish a session calendar on their website or in their research section. This calendar often includes the exact opening and closing times for each session, adjusted for daylight saving time changes. If you trade multiple pairs, checking your broker's calendar at the start of each month ensures you have the correct times, especially around daylight saving transitions.

Weekend and Holiday Closures

The forex market closes at 5 p.m. Eastern Time on Friday and does not reopen until 5 p.m. Eastern Time on Sunday. This means there is no trading on Saturday or Sunday. If major news breaks over the weekend — a geopolitical event, a central bank announcement, or an economic shock — the market cannot react until Sunday evening when Sydney opens.

Some brokers offer limited trading on Friday evening or Sunday evening during the transition, but liquidity is thin and spreads are wide. Major holidays also close the market or reduce trading volume. U.S. holidays like Thanksgiving and Christmas, UK holidays like Boxing Day, and Japanese holidays like New Year's Day all affect which sessions are fully active. Your broker will publish a holiday calendar showing when reduced hours or closures explore.

Which Session Is Best for Trading Specific Currency Pairs

Currency pairs move most actively during the session of the country whose currency is in the pair. The EUR/USD pair (euro and U.S. dollar) is most volatile during the London-New York overlap. The USD/JPY pair (U.S. dollar and Japanese yen) sees its largest moves during the Tokyo and New York sessions. The GBP/USD pair (British pound and U.S. dollar) is most active during London and New York hours.

If you trade exotic pairs — those involving smaller or emerging-market currencies — they may have the most volume during the session of their home country. For example, the USD/SGD pair (U.S. dollar and Singapore dollar) trades most actively during Asian hours. Checking your broker's volume and volatility data for each pair during each session helps you identify when that pair moves enough to trade profitably.

How to Plan Your Trading Schedule Around Market Hours

If you trade during your local business hours, you may only have access to one or two sessions. A trader in New York can trade the London-New York overlap easily but would need to wake up very early to catch the Tokyo session. A trader in Sydney can trade the Sydney-Tokyo overlap but would need to stay up late for the London-New York session. Knowing which sessions overlap with your available time helps you focus on the pairs and strategies that fit your schedule.

Some traders use automated trading systems or set alerts to notify them when price reaches certain levels, so they do not have to watch the screen during slow sessions. Others choose to trade only during the overlap windows when volume is highest. Your trading plan should account for which sessions you can realistically monitor and which pairs move enough during those times to make trading worthwhile.

Frequently Asked Questions

Can I trade forex on weekends?

No. The forex market closes at 5 p.m. Eastern Time on Friday and reopens at 5 p.m. Eastern Time on Sunday. Some brokers offer limited weekend trading in certain pairs, but liquidity is very low and spreads are much wider than during regular sessions. Most traders do not trade on weekends because price movement is minimal.

What time does the forex market open on Sunday?

The forex market opens at 5 p.m. Eastern Time on Sunday evening, when the Sydney session begins. This is the start of the trading week. If you observe a different time zone, convert 5 p.m. Eastern Time to your local time to find when trading opens for you.

Is the forex market open on U.S. holidays?

Most U.S. holidays close the New York session, but other sessions may still be active. For example, on Thanksgiving or Christmas, the Tokyo and London sessions may trade with reduced volume, but the New York session is closed. Your broker publishes a holiday calendar showing which sessions are closed or have reduced hours on specific dates.

Which session has the most trading volume?

The London-New York overlap, which runs from roughly 8 a.m. to noon Eastern Time, is the most active period. This is when both the London and New York markets are open at the same time, bringing the highest trading volume and the tightest spreads for most currency pairs.

Do all brokers use the same session times?

Session times are the same across all brokers because they are based on when financial centers actually open and close. However, brokers may display these times in different time zones or adjust them slightly based on their own trading hours. Always check your specific broker's platform to see the exact times they use.
