The horario de trading forex—the schedule of forex trading hours—is one of the most fundamental concepts for any currency trader. Unlike stock markets, the foreign exchange market operates nearly 24 hours a day, five days a week, across multiple global financial centres. Understanding when to trade, which sessions offer the best opportunities, and how time zones affect liquidity and volatility is essential for developing a profitable trading strategy. This guide covers everything you need to know about forex trading hours, from the four major sessions to practical use cases and risk management.
Horario de trading forex refers to the schedule of trading hours in the foreign exchange market. The forex market operates 24 hours a day, five days a week, from Sunday evening (22:00 GMT) to Friday evening (22:00 GMT). This continuous trading cycle is made possible by the geographic distribution of major financial centres—Sydney, Tokyo, London, and New York—which overlap at different times to provide near-constant market activity.
Unlike centralised exchanges such as the New York Stock Exchange (NYSE) or the London Stock Exchange (LSE), forex trading is conducted over-the-counter (OTC) through a global network of banks, brokers, and financial institutions. This decentralised structure means that there is no single opening or closing bell; instead, trading activity migrates from one financial centre to the next as the trading day progresses around the world.
According to the Bank for International Settlements (BIS) Triennial Central Bank Survey, the global forex market turned over $9.6 trillion per day in April 2025, with the London session accounting for approximately 38% of all global forex trading volume, followed by New York at 22%. These statistics underscore the importance of understanding when and where liquidity is concentrated.
ⓘ Key point: The forex market is not open 24/7. It operates from Sunday 22:00 GMT to Friday 22:00 GMT. Weekend trading is extremely limited and generally not recommended due to low liquidity and wide spreads.
The global forex market is divided into four major trading sessions, each corresponding to a primary financial centre. These sessions are defined by their local business hours and the currencies that are most actively traded.
The Sydney session opens at 22:00 GMT on Sunday and runs until 07:00 GMT (Monday to Friday). It is the first session of the trading week and is generally considered the quietest period, with lower volatility and narrower price ranges. The Australian dollar (AUD) and New Zealand dollar (NZD) are the most active currencies during this session, with the USD/AUD and USD/NZD pairs being particularly liquid.
The Tokyo session begins at 00:00 GMT and closes at 09:00 GMT. It overlaps with the Sydney session for approximately two hours (00:00–02:00 GMT). The Tokyo session is known for its focus on the Japanese yen (JPY), with the USD/JPY pair experiencing significant activity. This session often sets the tone for the Asian trading day and is influenced by economic data releases from Japan, China, and Australia.
The London session starts at 08:00 GMT and ends at 17:00 GMT. It is widely considered the most active trading session, accounting for a large share of global forex volume. London is the world’s largest forex trading centre, and the session features high liquidity, tight spreads, and substantial price movements. Major currency pairs such as EUR/USD, GBP/USD, and USD/CHF are particularly active during this period. The London session overlaps with both the Tokyo session (08:00–09:00 GMT) and the New York session (13:00–17:00 GMT), creating peak trading activity.
The New York session runs from 13:00 GMT to 22:00 GMT. It is the second most active session and is heavily influenced by economic data releases from the United States, including employment reports, inflation figures, and Federal Reserve announcements. The US dollar (USD) is the dominant currency, and pairs such as USD/JPY, EUR/USD, and USD/CAD are highly liquid. The session overlaps with London (13:00–17:00 GMT), which is considered the optimal trading window for many strategies.
ⓘ Note: Session times shift by one hour during daylight saving time transitions, as the US, Europe, and Australia change on different dates. Always verify the current session opening and closing times for your specific time zone.
The most dynamic periods in forex trading occur during the overlaps between sessions, when two major financial centres are open simultaneously. These overlaps combine the liquidity of both markets, often leading to increased volatility and tighter spreads.
The London–New York overlap is the most active trading period of the day. During these four hours, two of the world’s largest financial centres are open, generating the highest trading volume and liquidity. This overlap is ideal for day traders and those seeking to capture significant price movements. Major economic data releases from both the US and Europe often occur during this window, creating substantial trading opportunities.
The Tokyo–London overlap is relatively brief, lasting only about one hour. While not as liquid as the London–New York overlap, it can still provide good trading conditions, particularly for JPY pairs and other Asian currencies. This period may see increased activity following economic data releases from Japan or China.
The Sydney–Tokyo overlap occurs in the early Asian morning. It offers reasonable liquidity for AUD, NZD, and JPY pairs. While not the most volatile period, it can be suitable for traders who prefer a more measured pace and are focused on the Asia-Pacific region.
ⓘ Tip: The London–New York overlap is statistically the best period for active trading. According to Federal Reserve data on payment flows and settlement activity, nearly 60% of all interbank forex transactions occur during the London–New York overlap, highlighting its dominance in the global market.
Different trading sessions suit different types of traders and strategies. Below are some practical use cases that illustrate how traders can align their activities with the horario de trading forex.
Day traders aim to profit from intraday price movements. They typically prefer the London–New York overlap (13:00–17:00 GMT), which offers the highest liquidity, tightest spreads, and most significant price fluctuations. This period allows day traders to enter and exit positions efficiently, often within a few hours.
Swing traders hold positions for several days to weeks. They may focus on the London session (08:00–17:00 GMT) to capture medium-term momentum, while also monitoring the New York session for confirmation of trends. Swing traders are less concerned with intraday volatility and more interested in identifying major directional moves.
Scalpers execute dozens or hundreds of trades per day, seeking small, quick profits. They require extremely low spreads and high liquidity, making the London–New York overlap (13:00–17:00 GMT) and the core London session (08:00–13:00 GMT) the most suitable periods. Scalpers avoid quiet sessions such as Sydney or late New York, where spreads widen and liquidity thins.
Traders focusing on specific currencies should align their activity with the session when that currency is most active. For example, trading AUD/USD is optimal during the Sydney and Tokyo sessions (22:00–09:00 GMT), while GBP/USD performs best during the London session (08:00–17:00 GMT). Understanding these currency-specific patterns improves timing and execution.
📍 Scenario: A trader based in New York wants to trade EUR/USD during the most liquid period of the day. The trader plans to enter positions between 13:00 and 17:00 GMT (the London–New York overlap), as this window offers the tightest spreads and the highest probability of meaningful price movement. The trader also monitors key economic data releases from the US and Europe that are scheduled within this time frame, using them as potential catalysts for their trades.
Choosing the right trading hours is a personal decision that depends on your strategy, risk tolerance, and daily schedule. Use the following criteria to evaluate which sessions are most suitable for you.
Your trading style—scalping, day trading, swing trading, or position trading—will largely determine which sessions you should focus on. Scalpers and day traders need high liquidity and volatility, while swing and position traders can operate effectively across multiple sessions.
Trading in your local time zone can be more convenient and less stressful. For example, a trader in London can comfortably trade the full London session (08:00–17:00 GMT), while a trader in New York may prefer the New York session (13:00–22:00 GMT) and the London–New York overlap.
Major economic announcements—such as central bank rate decisions, employment reports, and inflation data—can create sharp price movements. Traders who wish to trade these events should align their sessions with the release times of key data from the US, Eurozone, UK, Japan, or Australia.
Before committing real capital, test your strategy during different sessions using a demo account. Measure the average spread, volatility, and slippage during each session to determine which offers the best conditions for your approach.
Keep a trading journal that records the session in which each trade was executed. Over time, you may find that your win rate or risk-reward ratio is significantly better during certain sessions, allowing you to refine your focus.
The table below provides a side-by-side comparison of the four major trading sessions, highlighting their key characteristics.
| Session | Opening Time (GMT) | Closing Time (GMT) | Liquidity | Volatility | Major Currency Pairs | Best For |
|---|---|---|---|---|---|---|
| Sydney | 22:00 | 07:00 | Low | Low | AUD/USD, NZD/USD | AUD/NZD traders, calm markets |
| Tokyo | 00:00 | 09:00 | Medium | Medium | USD/JPY, EUR/JPY, AUD/JPY | JPY pairs, Asian sessions |
| London | 08:00 | 17:00 | High | High | EUR/USD, GBP/USD, USD/CHF | Day trading, major pairs |
| New York | 13:00 | 22:00 | High | High | USD/JPY, EUR/USD, USD/CAD | US data, London overlap |
ⓘ Note: Liquidity and volatility levels can change during major economic events or geopolitical developments. The table above reflects typical conditions. Always monitor real-time market conditions and adapt accordingly.
Use this checklist to determine the best trading hours for your personal strategy and circumstances:
Reality: The forex market is open 24 hours a day from Sunday to Friday, but it is not open 24/7. Trading stops on Friday evening (22:00 GMT) and resumes on Sunday evening (22:00 GMT). Weekend trading is extremely limited and not recommended.
Reality: While volatility creates opportunity, excessive volatility can also lead to significant losses, especially with wide stops and slippage. Traders should match volatility to their risk tolerance and strategy. Quiet sessions like Sydney may be more suitable for conservative traders.
Reality: London is actually the largest forex trading centre, handling approximately 38% of global volume according to the BIS Triennial Survey. New York follows at 22%. Both are critical, but London is the undisputed leader.
Reality: Trading conditions vary significantly by session. Spreads widen, liquidity thins, and slippage increases during off-peak hours (e.g., the Sydney session or the late New York session). Your strategy must adapt to the session you are trading.
Reality: Economic data from Japan (Tokyo), the UK (London), and Europe (Frankfurt) can have just as much impact on the market as US releases. Traders should be aware of the global economic calendar, not just US events.
Forex trading involves significant risk, and trading during certain hours can amplify these risks. Periods of low liquidity, such as the Sydney session or the late New York session, can result in wider spreads, increased slippage, and less predictable price movements. Additionally, during major economic data releases or geopolitical events, volatility can spike dramatically, leading to large, rapid price swings that may trigger stop-loss orders prematurely or cause margin calls.
The Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA) have issued investor alerts warning retail traders about the risks of trading during illiquid periods. The NFA recommends that traders carefully review the execution and risk disclosure statements of their brokers to understand how order types and slippage may affect their trades during different market conditions.

'Horario de trading forex' translates to 'forex trading hours' in English. It refers to the 24-hour, five-day-a-week schedule during which the foreign exchange market is open for trading, spanning across major financial centres in different time zones.
The four major forex trading sessions are: Sydney (Asian session), Tokyo (Asian session), London (European session), and New York (US session). Each session has distinct characteristics in terms of volatility, liquidity, and the currency pairs that are most active.
The best time to trade forex is generally during the overlap between the London and New York sessions (13:00–17:00 GMT), when trading volume and liquidity are at their highest. This period often offers the tightest spreads and most significant price movements.
The forex market opens on Sunday at 22:00 GMT when the Sydney session begins and closes on Friday at 22:00 GMT when the New York session ends. The market operates 24 hours a day from Monday to Friday, with the weekend break over Saturday and Sunday.
The London-New York overlap (13:00–17:00 GMT) is the most active trading period, accounting for a significant portion of daily forex volume. During this overlap, traders experience higher liquidity, tighter spreads, and more pronounced price movements, making it ideal for day trading and short-term strategies.
The forex market closes on weekends because the major financial centres—Sydney, Tokyo, London, and New York—are closed for business. Although some digital platforms attempt to offer weekend trading, liquidity is extremely thin and spreads are typically much wider, making it less attractive for most traders.
The Sydney session is the first session to open each trading week, starting at 22:00 GMT on Sunday. It is generally the quietest session, with lower volatility and narrower price ranges. The Australian dollar (AUD) and New Zealand dollar (NZD) are the most actively traded currencies during this session.
Daylight saving time changes can shift session opening and closing times by one hour. The US and Europe switch on different dates, creating temporary overlaps that are shorter or longer than usual. Traders should adjust their schedules and be aware of these shifts to avoid missing optimal trading windows.
