A comprehensive, plain‑English guide to understanding forex market opening times—what they mean, how the 24/5 schedule works in practice, how to evaluate the best times to trade, common mistakes, and essential risk controls. Drawing on regulatory perspectives from the CFTC, NFA, FINRA, and the Bank for International Settlements.
Forex market opening times refer to the schedule of when the foreign exchange market becomes active and available for trading. Unlike most financial markets that have defined opening and closing bells, the forex market operates on a 24‑hour, five‑day‑a‑week schedule (commonly referred to as "24/5"). The market opens on Sunday at 5:00 PM Eastern Time (ET) and closes on Friday at 5:00 PM ET, resuming after the weekend break.
The Bank for International Settlements (BIS), in its 2022 Triennial Central Bank Survey, reported that the global forex market averages over $7.5 trillion in daily turnover. This continuous trading activity is made possible by the overlapping of major financial centres across different time zones: Sydney, Tokyo, London, and New York. As one centre closes, another opens, ensuring that there is always a market participant somewhere in the world ready to trade.
The concept of "opening times" in forex is therefore not a single moment but a rolling sequence of session starts. Each session has its own characteristics in terms of liquidity, volatility, and the types of currency pairs that are most active. Understanding this schedule is foundational to developing an effective trading strategy, as the time of day you trade can significantly influence your execution quality, spread costs, and risk exposure.
The Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA) provide educational materials that highlight the importance of understanding market hours for risk management. The NFA notes that trading during off‑hours or low‑liquidity periods can result in wider spreads and increased slippage, which are important factors for retail traders to consider. The Federal Reserve also publishes exchange‑rate data that reflects the continuous nature of the global forex market.

While the forex market is technically open 24 hours a day from Sunday evening to Friday afternoon, not all hours are created equal. Liquidity varies significantly between sessions, and the opening of each major session brings shifts in price behaviour that traders must anticipate. This guide will help you navigate these nuances and make informed decisions about when to trade.
The forex market's continuous operation is driven by the geographic distribution of its participants. Understanding the mechanics of how the market opens and transitions between sessions is key to appreciating its rhythm.
The trading week begins in the Asia‑Pacific region. On Sunday evening (ET), the Sydney session opens, followed a few hours later by Tokyo. As the Asian session progresses, London opens, and finally New York joins. The market then cycles through these sessions until Friday's New York close, after which trading halts for the weekend.
Each major financial centre has its own business hours, and the forex market effectively follows the sun around the globe:
Forex market opening times are affected by daylight saving time (DST) changes in the respective regions. The United States and Europe switch at different times, which can temporarily shift the overlap periods. For example, during certain weeks of the year, the London‑New York overlap may be shorter or longer than usual. Traders should always verify current times using a reliable forex market hours calendar, especially around DST transition dates.
The Financial Industry Regulatory Authority (FINRA) advises traders to be aware of the impact of DST changes on market liquidity. During the weeks when the US and UK are on different DST schedules, the London‑New York overlap is reduced by one hour, which can affect trading volumes and volatility. Always check the current session times before planning your trades.
The forex market is divided into four major trading sessions, each corresponding to a key financial centre. The following sections detail the opening and closing times, along with the key characteristics of each session.
Open: 10:00 PM ET (Sunday)
Close: 7:00 AM ET (Monday–Friday)
Key Pairs: AUD/USD, NZD/USD, EUR/JPY
Characteristics: Lowest liquidity, often sets the tone for the week. Moves can
be influenced by economic data from Australia and New Zealand. Spreads are typically wider.
Open: 7:00 PM ET (Sunday)
Close: 4:00 AM ET (Monday–Friday)
Key Pairs: USD/JPY, EUR/JPY, GBP/JPY
Characteristics: Moderate liquidity, influenced by Japanese economic data and
Bank of Japan policy. The session often sees range‑bound price action, with breakout potential
when London opens.
Open: 3:00 AM ET
Close: 12:00 PM ET
Key Pairs: EUR/USD, GBP/USD, USD/CHF, EUR/GBP
Characteristics: Highest liquidity (∼38% of global turnover). Volatility picks
up, with strong trends often starting during this session. Spreads are tightest.
Open: 8:00 AM ET
Close: 5:00 PM ET
Key Pairs: EUR/USD, USD/JPY, GBP/USD, USD/CAD
Characteristics: High liquidity (∼19% of global turnover). US economic data
releases (Non‑Farm Payrolls, CPI, GDP) often trigger sharp moves. The session closes out the
trading day.
Note: Times are based on Eastern Time (ET) and are indicative. Actual times may vary due to daylight saving changes. Always verify with a reliable source.
The periods when two major sessions are simultaneously open—known as session overlaps— are the most active and liquid times in the forex market. These overlaps are highly sought after by traders because they offer the tightest spreads and the most significant price movements.
This overlap occurs during the Asian session and is the least liquid of the two major overlaps. It is most relevant for traders focusing on JPY and AUD pairs. While volatility is moderate, it can present opportunities for breakouts ahead of the London session.
This is the most significant overlap in the forex market. With London and New York trading simultaneously, approximately 60% of global forex volume is concentrated in this window. This period offers the tightest spreads, the highest liquidity, and often the most dynamic price movements. Major US economic data releases (such as Non‑Farm Payrolls, CPI, and GDP) are typically scheduled during this window, adding to the volatility. This is the preferred trading time for most active traders, particularly those using short‑term or intraday strategies.
Between the New York close and the Sydney open (5:00 PM – 10:00 PM ET), the market is at its quietest. Liquidity is thin, spreads are wider, and price movements can be erratic. Similarly, the period between the Sydney close and the London open (7:00 AM – 3:00 AM ET) can also be relatively subdued. Trading during these quiet periods carries additional risks, including increased slippage and the potential for sudden, sharp moves on thin liquidity.
The Bank for International Settlements (BIS) reports that the London‑New York overlap accounts for a substantial portion of daily forex turnover. Data from the 2022 Triennial Survey indicates that trading activity peaks during these hours, with the highest concentration of transactions occurring between 8:00 AM and 12:00 PM ET. This underscores why many institutional traders concentrate their activity in this window. Source: BIS Triennial Central Bank Survey 2022.
Understanding forex market opening times allows traders to tailor their strategies to specific sessions. Here are three practical scenarios that illustrate how session timing affects trading decisions.
Lisa is a trend‑following swing trader who prefers to trade during the London session (3:00 AM – 12:00 PM ET). She has observed that EUR/USD often establishes clear directional trends during this session, influenced by European economic data and the opening of UK markets. She enters her trades within the first two hours of the London session and sets her take‑profit targets based on the expected momentum, using the London‑New York overlap to manage her exits.
David is a short‑term trader who focuses on US economic data releases. He targets the London‑New York overlap (8:00 AM – 12:00 PM ET), when most major US data is released. He uses an economic calendar to identify key events (such as Non‑Farm Payrolls or CPI) and enters trades based on the market's reaction to the data. He avoids trading during the quiet Asian session, where liquidity is thin and spreads are wider.
Kenji, based in Tokyo, specialises in scalping USD/JPY during the Tokyo session (7:00 PM – 4:00 AM ET). He focuses on the first few hours after the session opens, when volatility is highest, and takes small profits from tight ranges. He uses the Sydney‑Tokyo overlap as a secondary trading window, monitoring for breakouts that may precede the London session. He avoids the quiet period between the New York close and Sydney open.
Choosing the best time to trade depends on your trading style, strategy, and personal schedule. The following criteria will help you evaluate which sessions and overlaps are most suitable for your needs.
Your trading style is the primary determinant of your optimal trading hours:
The liquidity of a currency pair varies by session:
High‑impact economic data releases can create significant volatility. If your strategy relies on volatility, you may want to trade around these events. However, if you prefer stable price action, you may want to avoid the immediate aftermath of major releases. The Federal Reserve publishes a schedule of economic releases, and the BIS provides data on market activity around such events.
Finally, your personal schedule matters. Trading during hours when you are alert, focused, and free from distractions is essential for good decision‑making. For many traders, aligning with the London session (which corresponds to morning hours in the Americas and afternoon in Asia) offers a good balance of liquidity and personal availability.
The National Futures Association (NFA) recommends that traders keep a trading journal that includes the time of each trade. Over time, this data can reveal patterns—such as which sessions produce your best results—and help you refine your trading schedule for better performance.
The table below summarises the key characteristics of each major forex session, allowing for a side‑by‑side comparison of their features.
| Session | Open (ET) | Close (ET) | Liquidity | Typical Spreads | Key Pairs | Best For |
|---|---|---|---|---|---|---|
| Sydney | 10:00 PM | 7:00 AM | Low | Wider | AUD/USD, NZD/USD | Range traders, Asian session specialists |
| Tokyo | 7:00 PM | 4:00 AM | Medium | Medium | USD/JPY, EUR/JPY | JPY traders, breakout enthusiasts |
| London | 3:00 AM | 12:00 PM | Very High | Tight | EUR/USD, GBP/USD, USD/CHF | Trend followers, active day traders |
| New York | 8:00 AM | 5:00 PM | High | Tight | USD/JPY, USD/CAD, EUR/USD | News traders, US data traders |
| London‑NY Overlap | 8:00 AM | 12:00 PM | Highest | Very Tight | All major pairs | All active trading styles |
| Quiet Period (NY Close to Sydney Open) | 5:00 PM | 10:00 PM | Very Low | Widest | Limited liquidity | Avoid trading |
Note: Times are based on Eastern Time (ET). Adjust for daylight saving changes. Liquidity and spread characteristics are indicative and may vary by broker and market conditions.
Before you start trading in any session, use this checklist to ensure you are well‑prepared and aligned with market conditions.
This checklist is a guide, not a guarantee. Market conditions can change unexpectedly, and even the most liquid session can experience sudden shifts due to news or central bank intervention. Always maintain a disciplined risk management approach, regardless of the time of day.
Trader: Elena, a swing trader based in Europe.
Strategy: Trend‑following on the 4‑hour chart, holding positions for 2–5 days.
Monday: Elena checks the market opening on Sunday at 5:00 PM ET. She notes that the Sydney session has opened, but liquidity is thin. She avoids trading immediately and waits for the London session to open on Monday morning (3:00 AM ET).
Monday – London Session: At 3:00 AM ET, the London session opens. Elena observes that EUR/USD is breaking above a key resistance level. She enters a long position with a stop‑loss below the recent swing low and a take‑profit target at the next resistance level. She uses the London‑New York overlap (8:00 AM – 12:00 PM ET) to manage her position, adjusting her stop to breakeven after a 50‑pip move.
Tuesday – New York Session: US CPI data is released at 8:30 AM ET. Elena checks the data and sees that it is higher than expected, which strengthens the USD. She decides to take profits on her long EUR/USD position, as the pair is likely to pull back. She books a 120‑pip gain and closes the trade before the New York close at 5:00 PM ET.
Wednesday – Thursday: Elena reviews her trades and plans her next move. She notes that the London‑New York overlap has consistently been her most profitable trading window.
Friday: Elena avoids trading in the final hours before the New York close at 5:00 PM ET, as spreads tend to widen and volatility can be erratic. She closes any open positions before the weekend to avoid weekend gap risk.
Note: This is an illustrative scenario. Actual outcomes vary. Always conduct your own research and consult the latest market data before making trading decisions.
Misunderstandings about forex market hours can lead to poor trading decisions. Here are some of the most persistent mistakes and the reality behind them.
Reality: The forex market operates 24 hours a day, but only five days a week (Sunday 5:00 PM ET through Friday 5:00 PM ET). It is not open on weekends. Trading during the weekend is not possible, and any orders placed over the weekend will be executed at the market open on Sunday evening.
Reality: Liquidity varies dramatically between sessions. The London session is the most liquid, followed by New York. The Sydney and Tokyo sessions have lower liquidity, resulting in wider spreads and potentially higher slippage. Trading during low‑liquidity sessions requires additional caution.
Reality: While you can technically place trades at any time, the liquidity of specific pairs is tied to their regional sessions. For example, AUD/USD is most liquid during the Sydney session, while EUR/USD is most liquid during London and New York. Trading a pair outside its peak hours can result in wider spreads and less predictable price action.
Reality: While the Sunday open can have some gaps due to weekend news, the highest volatility typically occurs during the London‑New York overlap (8:00 AM – 12:00 PM ET), when multiple major centres are active and economic data releases are concentrated.
Reality: Limit orders can help you get better entry prices, but they do not eliminate the risk of wider spreads and lower liquidity. During quiet periods, even limit orders may not be filled at your desired price, or the market may gap past your order level.
Reality: DST changes in the US, UK, Europe, and Australia all affect the timing of session openings and overlaps. During the transition periods, the London‑New York overlap can shift by up to one hour, affecting liquidity and volatility. Traders should always check the current session times around DST changes.
Trading forex at different times of the day carries specific risks. Understanding these risks and implementing appropriate controls is essential for protecting your capital.
Trading forex carries a high level of risk and may not be suitable for all investors. The CFTC, NFA, and FINRA have all published investor alerts stating that the majority of retail forex traders lose money. The timing of your trades does not eliminate the inherent risks of forex trading—it only changes the nature of the risks you face. Never trade with money you cannot afford to lose, and always maintain strict risk management practices.

The Federal Reserve and BIS publications consistently remind participants that financial markets are inherently unpredictable. A disciplined approach to both timing and risk management is essential for long‑term survival and success in forex trading.
Answers to the most common questions about forex market opening times, compiled from regulatory guidance and trader best practices.
The forex market opens on Sunday at 5:00 PM Eastern Time (ET) and closes on Friday at 5:00 PM ET, operating 24 hours a day during that period. The market follows the global financial centres: Sydney opens first, followed by Tokyo, London, and New York.
The four major trading sessions are the Sydney session (10:00 PM – 7:00 AM ET), the Tokyo session (7:00 PM – 4:00 AM ET), the London session (3:00 AM – 12:00 PM ET), and the New York session (8:00 AM – 5:00 PM ET). Times are based on Eastern Time and account for daylight saving adjustments.
The best time to trade is during session overlaps, particularly the London‑New York overlap (8:00 AM – 12:00 PM ET), which offers the highest liquidity and tightest spreads. The Sydney‑Tokyo overlap (2:00 AM – 4:00 AM ET) is also active but with lower volatility.
Yes, the forex market closes on weekends. The market is open 24 hours a day from Sunday 5:00 PM ET through Friday 5:00 PM ET. Trading ceases over the weekend and resumes on Sunday evening.
Key risks include increased volatility and wider spreads during the Sunday opening and Friday closing periods. Also, trading during low‑liquidity sessions (such as late NY or early Sydney) can result in slippage and less predictable price movements.
Spreads are typically tightest during session overlaps when liquidity is highest, especially during the London‑New York overlap. Spreads tend to widen during the Sydney session, on weekends, and around major economic data releases.
The forex market opens on Sunday at 5 PM ET because that is when the Sydney (Australia) trading session begins, marking the start of the new trading week. This time is also after the New York close on Friday at 5 PM, creating the weekend gap.
A session overlap occurs when two major financial centres are trading simultaneously, such as the London‑New York overlap (8:00 AM – 12:00 PM ET). These periods offer the highest liquidity, tightest spreads, and often the most significant price movements, making them ideal for active traders.
