Forex markets open and close on a rolling basis across four major trading sessions, with no single "opening bell"

The foreign exchange market does not have one opening time because it operates across multiple time zones simultaneously. Instead, trading moves from one region to the next as the business day begins in each financial center. The four main sessions are Tokyo, London, New York, and Sydney, and they overlap in ways that create periods of higher and lower trading volume throughout the week.

The market opens on Sunday evening in the United States (around 5 p.m. Eastern Time) when trading begins in Sydney and Tokyo. It then closes on Friday evening in New York (around 5 p.m. Eastern Time). This means forex trading runs nearly 24 hours a day, five days a week, with no central exchange or single opening time like the stock market has.

Key Takeaways

  • Forex trading begins Sunday evening U.S. time in Sydney and Tokyo, and closes Friday evening U.S. time in New York.
  • The four main trading sessions—Tokyo, London, New York, and Sydney—each have their own opening and closing times based on local business hours.
  • Overlapping sessions, particularly London-New York overlap, see the highest trading volume and price movement.
  • Your ability to trade depends on your broker's hours, which may differ from the official session times.
  • Weekend gaps between Friday close and Sunday open can create price jumps when the market reopens.

The four main trading sessions and their times

Tokyo (Asia-Pacific session) opens at 7 p.m. Sunday Eastern Time and closes at 4 a.m. Monday Eastern Time. This session includes trading in Japan, Singapore, Hong Kong, and Australia. Volume is typically moderate, and the session is known for moving the Japanese yen and other Asian currencies.

London (European session) opens at 3 a.m. Eastern Time and closes at 12 p.m. (noon) Eastern Time. This is the second-largest trading center globally and overlaps with both Tokyo at the start and New York at the end. The London session often sees increased volatility and volume compared to Tokyo alone.

New York (North American session) opens at 8 a.m. Eastern Time and closes at 5 p.m. Eastern Time. This is the largest and most liquid session. The overlap between London and New York (8 a.m. to 12 p.m. Eastern) produces the highest trading volume of the entire week and the most significant price movements.

Sydney (Asia-Pacific session) opens at 5 p.m. Sunday Eastern Time and closes at 2 a.m. Monday Eastern Time. Sydney is the first major session to open each week and sets the tone for Asian trading. It overlaps slightly with Tokyo.

Why session times matter for trading volume and volatility

Different sessions attract different traders and institutions, which changes how much trading happens and how fast prices move. The Tokyo session is active but typically quieter than London or New York. Traders in Asia focus on Asian currency pairs and commodities tied to that region.

The London session is busier because it is a major financial hub and overlaps with both Asia closing and North America opening. Many institutional traders and banks execute large trades during London hours. When London and New York overlap (8 a.m. to 12 p.m. Eastern), you see the highest volume and the fastest price swings of the week. This overlap is when major economic news releases often occur and when spreads (the difference between buy and sell prices) tend to be tightest.

The New York session is the largest by volume. It closes the week on Friday at 5 p.m. Eastern Time, after which the market is closed until Sunday evening. This gap can create price jumps when the market reopens, especially if major news breaks over the weekend.

How to find your broker's exact trading hours

Your ability to trade depends on when your broker accepts orders, not on when the global market is technically open. Most brokers that serve U.S. customers offer trading during the four main sessions, but some may open earlier or close later than the standard times listed above. A few brokers offer limited weekend trading, though this is rare and usually comes with wider spreads.

Check your broker's website or trading platform for their specific hours. Look for a section labeled "Trading Hours," "Market Hours," or "Session Times." Your broker should list the hours in your local time zone or allow you to set your preferred time zone. If you trade during off-hours, you may face wider spreads, lower liquidity, or both, which means it costs more to enter and exit trades.

The weekend gap and why prices can jump on Sunday evening

The forex market closes at 5 p.m. Eastern Time on Friday and does not reopen until 5 p.m. Eastern Time on Sunday. During this two-day gap, no official forex trading occurs, but news and events can still move prices. If a major economic report, geopolitical event, or central bank announcement happens over the weekend, the market will open Sunday evening at a different price than it closed Friday.

This is called a gap, and it can work for or against you. If you held a position over the weekend, you might open your account Sunday evening to find your trade is worth significantly more or less than when you closed it Friday. Some traders avoid holding positions over the weekend for this reason. Others use the gap as a trading opportunity, betting that prices will move in a certain direction when the market reopens.

Daylight saving time and how it shifts session times

The United States, Europe, and other regions observe daylight saving time, but they do not all change on the same date. This creates temporary shifts in when sessions overlap. For example, when the U.S. switches to daylight saving time but Europe has not yet, the London session may open one hour earlier relative to New York time than it does the rest of the year.

Most brokers automatically adjust their displayed times when daylight saving time changes, but it is worth double-checking your broker's hours during the transition weeks in March and November. If you trade at the same time every day, you may need to shift that time by one hour for a few weeks during these transitions.

Which session is best for different trading styles

If you trade during Asian hours (Tokyo and Sydney), you will see lower volume and tighter spreads on Asian currency pairs like the Japanese yen and Australian dollar. This session suits traders who focus on Asia or who prefer quieter, less volatile conditions.

The London session is ideal if you want moderate to high volume without the extreme volatility of the New York session. Many traders use London hours to trade the euro and British pound.

The New York session is best if you want the highest volume, tightest spreads, and most price movement. It is also when most U.S. economic data is released. However, the fast pace and wide swings can be risky for inexperienced traders.

The London-New York overlap (8 a.m. to 12 p.m. Eastern) is the most active time of the week. Spreads are at their tightest, volume is highest, and major news often breaks during these hours. This overlap is when many professional traders concentrate their activity.

Frequently Asked Questions

What time does forex open on Monday?

Forex opens at 5 p.m. Eastern Time on Sunday evening, which is technically the start of the Monday trading week in Sydney and Tokyo. If you are in the U.S., this means you can begin trading Sunday evening. The New York session itself opens at 8 a.m. Eastern Time on Monday morning.

Can I trade forex on weekends?

Most brokers do not offer forex trading on weekends. The official market is closed Saturday and Sunday. A small number of brokers offer limited weekend trading, but spreads are usually much wider, and liquidity is lower. Check your broker's hours to see if they offer this option.

What happens if I hold a trade when the market closes on Friday?

Your position stays open, but you cannot close it until the market reopens Sunday evening. If prices move significantly over the weekend due to news or events, your trade may open at a very different price on Sunday. Some brokers charge overnight fees (called swaps or rollover fees) for holding positions over the weekend.

Does the forex market ever close during the week?

No. Once the market opens Sunday evening, it trades continuously through Friday at 5 p.m. Eastern Time with no breaks. Individual brokers may have brief maintenance windows, but the global market itself never closes during the five-day trading week.

Why do prices sometimes jump when the market opens on Sunday?

Prices jump on Sunday evening when major news broke over the weekend or when traders' expectations have changed since Friday's close. Since no one could trade over the weekend, the market opens at whatever price balances all the new information and orders waiting to be filled. This is called a gap.
