The London Session Forex Time is one of the busiest times in the world currency market. When key financial centers in Europe are open, there are significant price movements and substantial trade.
If you know when this session starts and ends in your time zone, you can make your trading hours more effective and avoid uncertainty around daylight saving time.
This is a guide to the London session, including the times in BST and GMT and how to change the London session to EST, IST, or any other local time you like. We’ll also talk about overlapping periods, key trading pairs, and how daylight saving time affects session times, all in simple terms.
What Is the London Session?
The London session is when the financial markets in London and across Europe are busiest, making the worldwide FX market very liquid.
In forex, the London session, also known as the European session, is the period when financial markets in London and Frankfurt, among other European centres, are the most active. This trading session drives a large volume of daily forex trading worldwide.
The forex hours of the London session are pegged to London time, which shifts between Greenwich Mean Time (GMT) during winter and British Summer Time (BST) during summer.
As the clocks move forward by one hour in late March, the session begins and ends one hour earlier in UTC. However, it goes back to normal GMT when they return in late October.
Why does this matter? Liquidity. During London’s trading hours, global banks, hedge funds, and institutional players are at work. Prices tend to be generally livelier, and trading volumes are much higher than in the Asian session.
Note, though, that these are market characteristics, not signals. The presence of high liquidity does not necessarily indicate that the company will be profitable; it only shows the intensity of its activity.
London Session Hours
The London session runs from 8:00 a.m. to 4:00 p.m. local time in London (GMT during winter and BST during summer).
The schedule for the London session follows the UK business-day rhythm. Here’s how it works:
- During GMT (winter months):
The London session opens at 8:00 a.m. GMT and closes at 4:00 p.m. GMT. - During BST (summer months):
The session is between 8:00 a.m. BST and 4:00 p.m. BST, which corresponds to 7:00 a.m. to 3:00 p.m. UTC.
A London trading session lasts 8 hours, though during daylight saving, it changes slightly relative to other time zones.
Sometimes, the US and Europe adjust clocks on different weeks. The overlap between the London and New York sessions shifts by one hour during those short periods.
To ensure everything is in the right place, traders who monitor several regions must constantly review the current state of the DST.

Session Overlaps (Most Active Windows)
The London session coincides with the Asian and New York sessions, which makes it the busiest and most liquid time of day for trading.
The forex market operates on a 24-hour cycle, although not every hour is equal. The most active time periods are when the trading sessions overlap.
Asia–London Overlap
- During GMT (winter): 7:00 a.m. – 8:00 a.m. GMT
- During BST (summer): 6:00 a.m. – 7:00 a.m. UTC
This is when Tokyo is still open and London is just beginning. Liquidity is increasing as European traders enter the market.
London–New York Overlap
- During GMT (winter): 12:00 p.m. – 4:00 p.m. GMT
- During BST (summer): 12:00 p.m. – 3:00 p.m. UTC
This overlap is the busiest time of day for FX traders worldwide. Two of the biggest financial centers, London and New York, are online. That means more trades and smaller spreads, but the essential data releases could make the market more volatile.
Overlaps are essential because they are where liquidity comes together, helping prices find their way. But traders should remember that volatility can work both ways. It delivers both chances and risks in equal amounts down the road.
Best Pairs & Typical Behaviour
The most active pairs during the London session are EUR, GBP, and CHF crosses, characterised by high liquidity and pronounced intraday moves.
When discussing the most appropriate currency pairs to trade during the London session, it is better to focus on currencies most closely tied to Europe and the UK. Examples of frequently used currency pairs are:
- EUR/USD
- GBP/USD
- USD/CHF
- EUR/GBP
- GBP/JPY
These currency pairs attract strong order flow because they are associated with the euro, pound, and Swiss franc, currencies closely linked to London and Europe.
Most European economic data releases, such as inflation, employment and GDP, are released in the London morning. Traders usually watch these events, as they can impact volatility in the short run for the EUR and GBP pairs.
Later in the session, when the London-New York overlap occurs, US data releases (e.g., CPI or NFP) can further influence market direction.
Want to know a secret? Although this session is liquid, spreads can still widen sharply around high-impact announcements. This is why the experienced teams will review release schedules and conduct disciplined risk management.
DST & Changeover Guide
The London market opens at 8.00 am local time throughout the year, and the UTC equivalent is between GMT and BST because of daylight saving time.
If you’ve ever wondered, “When does the London session open?” The answer depends on the time of year.
Here’s the simple breakdown:
- GMT (Winter): 8:00 a.m. – 4:00 p.m. GMT
- BST (Summer): 8:00 a.m. – 4:00 p.m. BST (which equals 7:00 a.m. – 3:00 p.m. UTC)
British Summer Time (BST) is the period when clocks are advanced by one hour, usually at the end of March. Greenwich Mean Time (GMT) is reinstated at the end of October, when the clocks are turned back.
Why it matters
The US observes daylight saving time (EDT/EST) too, but not on the exact dates every year. When one region shifts before the other, the overlap between the London and New York sessions shifts by about an hour. That short window can confuse traders managing multiple time zones.
To check which time standard is active today, simply search “current time in London.” Reliable sources like the Bank of England or timeanddate.com confirm whether BST or GMT is in effect.

A: The Asia-London overlap occurs when Tokyo closes and London opens, i.e. 7:00 a.m. – 8:00 a.m. GMT in the winter or 6:00 a.m. – 7:00 a.m. UTC in summer. This window tends to be moderate as the liquidity moves between regions.
A: The most popular instruments are EUR/USD, GBP/USD, USD/CHF, and EUR/GBP. These pairs are likely to record high movements since they are associated with the European and UK currencies. The state of things, however, is changeable daily; no pair is “best” for all traders.
A: The first few hours after the London open (8:00 a.m. local time) and the London-New York overlap are when many of its participants are active. These periods are when greater amounts and quicker price discovery may occur, though they may be volatile.
A: Not exactly. The session stays fixed at 8:00 a.m. to 4:00 p.m. London time. However, as the UK is a daylight saving time nation, its time zone UTC switches between GMT and BST each year.
