Understanding forex market open and close times is fundamental to successful currency trading. The forex market is unique in that it operates nearly around the clock, but not all hours are created equal. This guide explains the structure of global trading sessions, the best times to trade, how to evaluate session characteristics, and the risks associated with different trading hours.
The foreign exchange market is a decentralized, over-the-counter (OTC) market that operates 24 hours a day, five days a week. The market opens on Sunday at 5:00 PM Eastern Time (ET) and closes on Friday at 5:00 PM ET. This continuous operation is made possible by the global network of banks, financial institutions, brokers, and traders located in different time zones around the world.
According to the Bank for International Settlements (BIS) Triennial Central Bank Survey, the global foreign exchange market had an average daily turnover of US$9.6 trillion in April 2025, with trading activity distributed across the major financial centers. The BIS data shows that trading volume is not evenly spread throughout the day; it peaks during the overlap of the London and New York sessions, and is significantly lower during the Asian session and weekends.
The forex market's 24/5 schedule is driven by the time zones of the four major financial centers: Sydney, Tokyo, London, and New York. Each center has its own trading hours, and the market effectively "moves" from one center to the next as the business day unfolds around the globe.
The forex market is divided into four major trading sessions, each corresponding to a major financial center. The table below shows each session's approximate open and close times in Eastern Time (ET) and UTC.
| Session | Location | Open (ET) | Close (ET) | UTC Equivalent | Key Characteristics |
|---|---|---|---|---|---|
| Sydney | Australia/Asia | 5:00 PM (Sun) | 2:00 AM (Mon) | 22:00 – 07:00 | Low volatility; thin liquidity; minor pairs active |
| Tokyo | Japan/Asia | 7:00 PM | 4:00 AM | 00:00 – 09:00 | USD/JPY, AUD/JPY, NZD/JPY active; moderate volatility |
| London | UK/Europe | 3:00 AM | 12:00 PM | 08:00 – 17:00 | High volume; most active session; all majors active |
| New York | USA/Americas | 8:00 AM | 5:00 PM | 13:00 – 22:00 | High volume; overlaps with London; USD pairs active |
The Sydney session is the first to open on the trading week, starting at 5:00 PM ET on Sunday. It is considered a low-volatility session with thin liquidity. Currency pairs involving the Australian dollar (AUD), New Zealand dollar (NZD), and Japanese yen (JPY) are most active during this session. Due to lower liquidity, spreads can be wider, and price movements can be less predictable.
The Tokyo session opens at 7:00 PM ET and overlaps with the Sydney session until 2:00 AM ET. The Tokyo session is characterized by moderate volatility, with the USD/JPY pair being the most actively traded. News from Japan and Asian markets often influences price action during this session. The Japanese yen is a key currency in carry trades, so interest rate differentials can drive significant movements.
The London session, opening at 3:00 AM ET, is widely considered the most active forex trading session. It accounts for the largest share of global trading volume, as London is the world's largest forex trading hub. All major currency pairs (EUR/USD, GBP/USD, USD/JPY, USD/CHF) are highly liquid during this session. The European session also overlaps with both the Tokyo session (for about two hours) and the New York session (for about four hours).
The New York session opens at 8:00 AM ET and closes at 5:00 PM ET. It overlaps with the London session from 8:00 AM to 12:00 PM ET, which is the highest volume and most volatile period of the trading day. USD-related pairs (EUR/USD, USD/JPY, USD/CAD) see the most activity during this session. Economic data releases from the U.S. (NFP, CPI, GDP, etc.) often cause sharp price movements during the New York session.
The session overlaps are the periods when two major trading sessions are open simultaneously. These overlaps are characterized by higher liquidity, tighter spreads, and increased volatility.
This overlap occurs during the latter part of the Sydney session and the beginning of the Tokyo session. While it is the least active overlap, it does provide some increase in liquidity for AUD/JPY and NZD/JPY pairs.
This is a brief overlap that occurs at the start of the London session and the end of the Tokyo session. While short, it can see increased activity in the GBP/JPY and EUR/JPY pairs, as traders from both regions are active.
This is the most important trading window of the day. The overlap between the London and New York sessions lasts approximately four hours, during which both the world's largest forex hubs are active. This period accounts for the highest volume, tightest spreads, and most significant price movements. Major U.S. economic data releases typically occur during this overlap, adding to volatility. This is the preferred trading time for most day traders and scalpers.
Day traders and scalpers benefit most from the London–New York overlap (8:00 AM – 12:00 PM ET), where volatility and liquidity are at their peak. During this period, price movements are typically strong and trends are more reliable, making it easier to capture intraday moves. Scalpers can also benefit from tighter spreads, which reduce transaction costs.
Swing traders, who hold positions for several days to weeks, do not need to be as concerned with specific trading hours. However, they often choose to enter or exit positions during the London or New York sessions to take advantage of higher liquidity and tighter spreads.
Position traders who hold positions for months are generally unaffected by session-specific characteristics. However, they should still be aware of the weekend gap and the potential for significant volatility during major economic releases.
News traders often focus on the New York session, as it coincides with major U.S. economic data releases (such as Non-Farm Payrolls, CPI, and FOMC decisions). These events can cause significant volatility and sharp price movements, offering opportunities for rapid profits—but also substantial risk.
Different currency pairs have distinct patterns based on their home sessions:
Choosing the right trading hours is a strategic decision that depends on your trading style, personality, and availability. The table below helps you evaluate which session aligns with your trading approach.
| Trading Style | Best Session | Why It Works | Key Considerations |
|---|---|---|---|
| Scalping | London–New York Overlap | High liquidity, tight spreads, consistent price movement | Requires fast execution; high concentration; risk of slippage |
| Day Trading | London or New York | Strong trends, clear setups, active price action | Focus on major pairs; avoid trading during lunch hours |
| Swing Trading | London or New York (entry/exit) | Better liquidity for optimal entry/exit prices | Holding over sessions; aware of overnight risk |
| Position Trading | Any session (but avoid low liquidity) | Long-term; session timing less critical | Watch for weekend gaps and major news |
| News Trading | New York (U.S. data) or London (UK/ECB data) | High volatility around major data releases | Extreme risk; slippage; spread widening; avoid if risk-averse |
Use this checklist to determine which session fits your trading needs:
Scenario: James is a part-time trader based in New York. He works a full-time job from 9:00 AM to 5:00 PM, so he can only trade in the evenings. He wants to trade EUR/USD and USD/JPY.
Analysis: James evaluates his options:
Decision: James chooses to trade during the Tokyo and Sydney sessions because they fit his schedule. He adjusts his strategy to account for lower volatility and wider spreads. He focuses on the USD/JPY pair, which is most active during the Tokyo session. He uses wider stop-losses and lower position sizes to account for the potentially less predictable price action.
Outcome: James is able to trade consistently without conflicting with his day job. While his profit potential is lower than during the London-New York overlap, his strategy is sustainable and fits his lifestyle. He regularly reviews his performance and adjusts his approach as needed.
Lesson: The best trading session is the one that fits your schedule, personality, and trading style. James's realistic approach—adapting his strategy to the available sessions—is more sustainable than forcing himself to trade during hours that don't work for him.
The forex market closes on Friday at 5:00 PM ET and reopens on Sunday at 5:00 PM ET. During this interval, geopolitical events, economic data releases, and other news can cause significant price gaps. If you hold positions over the weekend, you are exposed to the risk of a sharp price movement against your position when the market reopens. The CFTC and NFA both caution traders about the risks of holding leveraged positions over weekends.
During the Sydney session and periods between sessions, liquidity is lower, which can result in wider spreads and higher slippage. This increases the cost of trading and can make it harder to execute orders at your desired price. The Financial Industry Regulatory Authority (FINRA) emphasizes that traders should be aware of these conditions and adjust their risk management accordingly.
Major economic data releases (NFP, CPI, GDP, central bank decisions) can cause extreme volatility within seconds. This can lead to slippage, stop-loss hunting, and rapid price swings. While volatility can offer opportunities, it also presents significant risk. The CFTC warns that retail traders often underestimate the risk of trading during news events.
Forex trading involves significant risk, including the potential loss of all invested capital. Trading during low-liquidity hours or holding positions over the weekend increases your exposure to market gaps and slippage. Always use appropriate risk management practices.
Always verify current rules, fees, spreads, rates, broker availability, and platform terms with the relevant authority or provider before trading. Regulatory requirements, leverage limits, and product availability change over time.

The forex market is open 24 hours a day, five days a week, from Sunday 5:00 PM ET to Friday 5:00 PM ET. This continuous trading is made possible by overlapping global trading sessions in Sydney, Tokyo, London, and New York.
The four major sessions are: Sydney (Asian session), Tokyo, London (European session), and New York (American session). Each has its own trading characteristics, volatility, and active currency pairs.
The best time to trade is typically during the overlap of the London and New York sessions, from 8:00 AM to 12:00 PM ET, when liquidity and volatility are highest. However, the optimal time depends on your strategy and the currency pairs you trade.
The London session (3:00 AM to 12:00 PM ET) is generally the most volatile due to the high trading volume from European banks, institutions, and hedge funds. The overlap with the New York session from 8:00 AM to 12:00 PM ET is also highly volatile.
The weekend gap refers to the price gap that can occur between the Friday close at 5:00 PM ET and the Sunday open at 5:00 PM ET. News events over the weekend can cause significant price jumps, increasing risk for traders holding positions over the weekend.
Trading hours affect volatility, liquidity, and spreads. Lower liquidity during off-hours can widen spreads and increase slippage, while higher volatility during overlaps can lead to rapid price movements. A good risk management strategy accounts for these variations.
Most regulated forex brokers offer 24/5 trading from Sunday to Friday, but some brokers may have additional restrictions for certain account types or during specific holidays. Always check your broker's specific trading hours and holiday schedule.
Low-liquidity hours (such as late New York session or early Sydney session) can result in wider spreads, higher slippage, and less predictable price movements. These conditions can make it harder to execute trades at desired prices and increase the risk of stop-loss being hit prematurely.
