Timing shapes everything in forex, not because the market closes, but because liquidity does not stay constant. The four forex trading sessions each carry a different character: different currencies in focus, different volumes, different spread conditions.
A trader who understands when each session runs, when two sessions overlap, and how forex market times shift around daylight saving changes is working with a clearer picture than one who treats the 24-hour clock as a uniform window.
This guide maps out forex market hours across all four major sessions: Sydney, Tokyo, London, and New York. It identifies where volume peaks and explains what each window may mean for the pairs you trade.
Key Points
- The four main forex trading sessions are Sydney, Tokyo, London, and New York, with each session showing different levels of liquidity, activity, and commonly traded currency pairs.
- The London and New York overlap from 13:00 to 17:00 GMT is often one of the most active periods, as European and US market participants are active at the same time.
- Forex market hours may shift during daylight saving time changes, so session times should be checked against current broker or platform hours.
How Forex Market Trading Session Work
The forex market has no central exchange. It operates as a decentralised, over-the-counter (OTC) network of banks, brokers, institutions, and individual traders connected electronically across global financial centres. Because those centres span different time zones, the market remains open continuously as each region takes over from the last.
Trading begins each week when Asia-Pacific financial centres open on Monday morning local time, and closes when New York wraps up on Friday afternoon. Between those two points, forex market working hours are shaped by which financial centres are active at any given moment, rather than by a single exchange bell.
Volume often increases when major financial centres overlap, while spreads may tighten and price movement can become more active. During quieter periods, participation may decline, which can lead to thinner liquidity.
The four sessions that define standard forex market trading hours are Sydney, Tokyo, London, and New York.
| Session | Opens (GMT) | Closes (GMT) | Key Currency Pairs |
| Sydney | 22:00 | 07:00 | AUD/USD, NZD/USD, AUD/JPY, NZD/JPY |
| Tokyo | 00:00 | 09:00 | USD/JPY, AUD/JPY, NZD/JPY, AUD/USD |
| London | 08:00 | 17:00 | EUR/USD, GBP/USD, EUR/GBP, USD/CHF |
| New York | 13:00 | 22:00 | EUR/USD, GBP/USD, USD/CAD, USD/CHF |

The Four Forex Trading Sessions Explained
Each session reflects the trading activity of the financial centres operating during its hours. Volume, spreads, and the currency pairs most actively traded all shift as the day cycles through these windows.
The Sydney Session
The Sydney session runs from 22:00 to 07:00 GMT and marks the start of the forex trading week, as Australian markets open on Monday morning local time.
It usually has the lightest trading volume of the four main sessions. This is because fewer major financial centres are active during this period, which can reduce overall market participation and liquidity.
Activity is often more focused on pairs linked to the Australian dollar and New Zealand dollar, such as AUD/USD, NZD/USD, AUD/JPY, and NZD/JPY. Regional data releases, including Australian employment figures or Reserve Bank of Australia commentary, may also influence price movement during Sydney hours.
For traders watching other major pairs, this session often acts as a quieter period before liquidity increases during the Tokyo session.
Key features:
- Session Hours: 22:00 to 07:00 GMT
- Commonly Active Pairs: AUD/USD, NZD/USD, AUD/JPY, and NZD/JPY
- Typical Volume: Usually the lightest of the four main sessions
- Market Drivers: Australian and New Zealand data releases, and Reserve Bank of Australia updates
- Weekly Context: Sets the early tone after the weekend market break
The Tokyo Session
The Tokyo session runs from 00:00 to 09:00 GMT and is often known as the Asian session. It covers a key period of activity across Japan, China, Hong Kong, and Singapore.
Trading volume is usually higher than the Sydney session as more Asian financial centres open. However, it is often quieter than the London and New York sessions, as fewer large global institutions are active during these hours.
Activity is often more focused on Japanese yen pairs, such as USD/JPY, EUR/JPY, and GBP/JPY. Price movement may also be more range-bound compared with the London or New York sessions, especially when there are fewer major economic releases.
Japanese economic data, Bank of Japan commentary, and trade balance figures may influence price movement during Tokyo hours. Activity can also pick up near the end of the session as European markets prepare to open, particularly in yen crosses such as EUR/JPY.
Key features:
- Session Hours: 00:00 to 09:00 GMT
- Commonly Active Pairs: USD/JPY, EUR/JPY, and GBP/JPY
- Typical Price Action: Often more range-bound than London or New York
- Market Drivers: Japanese economic data and Bank of Japan updates
- Main Overlap: Tokyo–London overlap from 08:00 to 09:00 GMT
The London Session
The London session runs from 08:00 to 17:00 GMT and is usually the largest forex trading session by volume. It marks the opening of European markets, bringing in banks, institutional funds, and major liquidity providers at the same time.
Trading volume tends to rise during this session because London is a major global centre for foreign exchange activity. This may support tighter spreads and more active price movement across major currency pairs.
Activity is often more focused on pairs linked to the euro, pound, and US dollar, such as EUR/USD, GBP/USD, EUR/GBP, and USD/CHF. European data releases, including Eurozone inflation figures, German industrial output, and Bank of England decisions, may also influence price movement during London hours.
The session becomes even more active when it overlaps with New York from 13:00 to 17:00 GMT, as both European and US market participants are active at the same time.
Key features:
- Session Hours: 08:00 to 17:00 GMT
- Peak Activity: Often high during the London open and the London–New York overlap
- Commonly Active Pairs: EUR/USD, GBP/USD, EUR/GBP, and USD/CHF
- Market Drivers: European economic data and central bank updates
- Main Overlap: London–New York overlap from 13:00 to 17:00 GMT
The New York Session
The New York session runs from 13:00 to 22:00 GMT and is one of the most active periods in the forex market. It also overlaps with the London session from 13:00 to 17:00 GMT, which is widely viewed as one of the most active windows of the trading day.
Trading activity is often focused on US dollar pairs, such as EUR/USD, GBP/USD, USD/JPY, and USD/CAD. This is because the US dollar is widely used across global forex transactions, making New York an important session for major currency pairs.
US economic releases, including non-farm payrolls, Consumer Price Index (CPI) data, and Federal Reserve announcements, may also influence price movement during this session. These releases can affect forex, indices, commodities, and bond markets at the same time.
Activity is usually strongest during the London and New York overlap. After London closes at 17:00 GMT, trading volume may gradually slow, although the New York session remains open until 22:00 GMT.
Key features:
- Session Hours: 13:00 to 22:00 GMT
- Most Active Window: London–New York overlap, 13:00 to 17:00 GMT
- Commonly Active Pairs: EUR/USD, GBP/USD, USD/JPY, and USD/CAD
- Typical Slowdown: After the London close at 17:00 GMT
Forex Market Trading Hours: How Session Overlaps Shape Liquidity
Forex session overlaps are more than shared trading hours. They are handover periods, where traders from one major region are closing, adjusting, or defending positions while another region is entering the market with fresh orders.
This is why overlap windows can feel different from normal session hours. Liquidity may rise, spreads may tighten, and price movement may become more reactive to news, order flow, and changing market sentiment.
However, higher volume does not always mean smoother price direction. In some cases, an overlap can extend an existing move. In others, it can interrupt the trend as a new group of market participants prices the same information differently.
The London–New York Overlap
The London and New York overlap runs from 13:00 to 17:00 GMT and is usually the most active period of the forex trading day.
This window brings together two major sources of liquidity: European market flow and US market flow. It is also when many US economic releases are published, including inflation data, labour market reports, and Federal Reserve updates.
That combination can make price movement more active across major pairs such as EUR/USD, GBP/USD, USD/JPY, and USD/CHF. A move that begins during the London morning may continue once New York opens, but it may also reverse if US data changes the market’s view.
The Tokyo–London Overlap
The Tokyo and London overlap runs from 08:00 to 09:00 GMT. It is much shorter than the London and New York overlap and usually has lower trading volume.
This one hour window marks the shift from Asian market activity to European market activity. For pairs such as EUR/JPY, GBP/JPY, and EUR/USD, this period can show whether price movement from the Asian session is being accepted, faded, or repriced by European participants.
The Tokyo and London overlap is brief, but it can still be useful from an educational perspective. It highlights how liquidity changes when one region exits and another enters, especially after major Asian data releases or Bank of Japan commentary.
Why Overlaps Matter Beyond Higher Volume
The value of session overlaps is not just that more traders are active. It is that different types of market participants are active at the same time.
For example, institutional desks, banks, macro funds, and short-term traders may all respond to the same price level for different reasons. Some may be reacting to economic data. Others may be managing risk, closing positions, or adjusting exposure before the next session begins.
This helps explain why overlap periods may produce stronger moves, false breakouts, or sudden reversals, depending on liquidity, order flow, and the market’s reaction to new information. The market is processing both liquidity and interpretation at the same time.
How Daylight Saving Time Shifts Forex Market Hours
Forex market hours are often shown in GMT or UTC so traders can compare session times using a standard reference point. GMT and UTC do not change, but the local opening hours of major financial centres may shift when daylight saving time begins or ends.
This mainly affects sessions linked to regions that observe daylight saving time, such as Sydney, London, and New York. Tokyo is usually unchanged because Japan does not observe daylight saving time.
The key point is that daylight saving changes do not happen everywhere at the same time. The US usually shifts in March and November, while the UK and Europe usually shift in March and October. Because of this, forex session overlaps may briefly look different during transition weeks.
The table below gives a general guide to normal and daylight saving forex market hours in GMT. Broker platform times may vary, especially around daylight saving transition dates.
| Session | Normal Time (GMT) | Daylight Saving Time (GMT) |
| Sydney | 22:00 to 07:00 | 21:00 to 06:00 |
| Tokyo | 00:00 to 09:00 | 00:00 to 09:00 |
| London | 08:00 to 17:00 | 07:00 to 16:00 |
| New York | 13:00 to 22:00 | 12:00 to 21:00 |
| Tokyo–London Overlap | 08:00 to 09:00 | 07:00 to 09:00 |
| London–New York Overlap | 13:00 to 17:00 | 12:00 to 16:00 |

Which Currency Pairs Are Most Active During Each Forex Trading Session?
Currency pair activity often follows the financial centres that are open during each forex trading session.
During the Sydney and Tokyo sessions, activity often clusters around AUD, NZD, and JPY pairs. This is because Australian, New Zealand, and Japanese market participants are more active during these hours, while regional data releases and Asia-Pacific risk sentiment may also influence price movement.
When London opens, liquidity broadens across EUR and GBP pairs as European banks, institutions, and market makers become active. USD pairs remain active across most sessions, but liquidity often peaks during the London and New York overlap, when European flow, US economic data, and dollar demand meet in the same window.
The table below summarises the sessions where selected major pairs often see higher activity and the common drivers linked to those periods. This serves as a guide, not a fixed rule. Economic data, central bank updates, and market sentiment may still affect any currency pair at any time.
| Currency Pair | Most Active Session(s) | Key Driver |
| EUR/USD | London, New York | Eurozone & US macro data |
| GBP/USD | London, New York | UK & US economic releases |
| USD/JPY | Tokyo, New York | BoJ policy, US data |
| AUD/USD | Sydney, Tokyo | Australian data, commodity prices |
| NZD/USD | Sydney, Tokyo | New Zealand data, risk sentiment |
| EUR/JPY | Tokyo–London overlap | European open, BoJ direction |
| USD/CAD | New York | Canadian data, oil prices |
| USD/CHF | London, New York | Safe-haven flows, US data |

Why Forex Trading Sessions Matter for Market Timing
Forex trading sessions show how liquidity moves through the market, not just when the market is open. Each session brings a different mix of participants, currency pairs, volume, and price behaviour.
This matters because the same pair may behave differently at different times of day. A quiet move during Sydney can look very different once London opens. A trend from the European morning may strengthen, pause, or reverse when New York enters.
Session timing does not replace fundamental or technical analysis. It adds context. For traders, the key question is not only what to trade, but also when market conditions may be most suited to that pair, setup, or level of activity.
FAQ
What are the forex trading sessions?
The four major forex trading sessions are Sydney, Tokyo, London, and New York. These sessions follow the business hours of major financial centres and create a 24 hour trading cycle from Monday morning in Asia-Pacific to Friday evening in New York.
What are the forex market hours in UTC?
In UTC, the standard forex market hours are: Sydney: 22:00 to 07:00, Tokyo: 00:00 to 09:00, London: 08:00 to 17:00, and New York: 13:00 to 22:00. These hours may shift during daylight saving time changes in the US, UK, Europe, and Australia.
When is the forex market most active?
The forex market is often most active during the London and New York overlap, which runs from 13:00 to 17:00 GMT. During this period, European and US market participants are active at the same time, which may support higher liquidity and tighter spreads on major pairs such as EUR/USD and GBP/USD.
Does the forex market ever close?
Yes. The forex market usually closes from around 22:00 GMT on Friday to 22:00 GMT on Sunday. This is known as the weekend gap. Some brokers may also apply short maintenance windows during low-liquidity periods.
What is a forex session overlap?
A forex session overlap occurs when two major trading sessions are simultaneously open. The most significant is the London and New York overlap (13:00 to 17:00 UTC), when both the world’s largest forex hub and the most USD-intensive session are active at the same time.
During this window, EUR/USD and GBP/USD often see higher liquidity and tighter spreads compared with quieter session periods. Overlaps matter because concentrated participation tends to produce tighter bid-ask spreads and more directional price action than quieter off-peak windows.
How does daylight saving time affect forex market times?
Daylight saving time can shift forex session hours in GMT or UTC because local market opening times move in regions such as the US, UK, Europe, and Australia. Since these regions do not change clocks on the same dates, session overlaps may temporarily shift during March, October, and November.
Which currency pairs are most active during the Asian forex session?
During the Asian forex session, JPY pairs such as USD/JPY, EUR/JPY, and GBP/JPY are often more active. AUD/USD and NZD/USD may also see higher activity during Sydney and Tokyo hours due to Australian, New Zealand, and Asia-Pacific market drivers.
