Best Time to Trade Forex: Sessions, Overlaps and Costs
In this article
The best time to trade Forex depends on the currency pair and strategy, but the London–New York overlap is generally one of the most active periods. During this window, liquidity in major pairs tends to be higher and spreads can be tighter, although conditions vary by broker and market activity.
The best time to trade Forex depends on the currency pair and trading strategy, but the London–New York overlap is generally one of the most active periods of the day. With both major financial centres open, liquidity tends to be higher and spreads on major currency pairs can be tighter.
Forex trades 24 hours a day during the working week, but market conditions are not consistent throughout the day. Liquidity, spreads and volatility change as different financial centres open and close.
Quick Takeaways
- Forex trading is commonly divided into four main sessions: Sydney, Tokyo, London and New York.
- The London–New York overlap is generally one of the most liquid periods for major currency pairs.
- Higher liquidity can contribute to tighter spreads, although actual spreads depend on the broker and market conditions.
- Economic announcements can cause rapid price movements, wider spreads and slippage, even during normally liquid periods.
- Positions held beyond a broker's daily rollover time may incur an overnight fee or receive a credit.
How Does the 24-Hour Forex Market Work?
Unlike shares traded on a centralised stock exchange, foreign exchange is an over-the-counter (OTC) market. Trading takes place through a global network of banks, financial institutions, brokers and other market participants.
As one major financial centre closes, another opens. This creates an almost continuous market from Monday to Friday.
CFDs that track currency pairs generally follow the underlying forex market, although exact trading hours can vary between brokers. If you are new to derivatives, understanding CFD trading can help explain how CFDs provide exposure to currency price movements without ownership of the underlying asset.
The trading day is commonly divided into four main sessions:
Forex Session | Approximate Hours (UTC) |
|---|---|
Sydney | 22:00-07:00 |
Tokyo | 23:00-08:00 |
London | 08:00-16:00 |
New York | 13:00-21:00 |
London–New York Overlap | 13:00-16:00 |
Note: Session times are approximate and may shift because of daylight-saving changes. Trading hours can also vary between brokers.
London is the world's largest centre for foreign exchange trading. According to the Bank for International Settlements' 2025 Triennial Survey (BIS), UK sales desks accounted for 38% of global FX turnover in April 2025.

Why Do Forex Session Overlaps Matter?
Forex activity is not distributed evenly throughout the day. Trading volume and liquidity tend to increase when major financial centres are open at the same time.
Two commonly watched periods are:
- London–New York overlap: Roughly 13:00–16:00 UTC based on the session times above. European and North American market participants are active at the same time, which can increase liquidity and trading activity in major pairs such as EUR/USD and GBP/USD.
- Tokyo–London transition: The end of Asian trading and the beginning of European trading can bring a change in liquidity and volatility, particularly in JPY and European currency pairs.
In forex, liquidity describes how easily a currency pair can be bought or sold without significantly affecting its market price.
When liquidity is high, greater competition between liquidity providers can result in narrower bid and ask prices. This can reduce the spread — the difference between the bid and ask price and one of the main trading costs faced by retail traders.
Typical conditions may look like this:
Session / Window | Relative Liquidity | Typical Spread Conditions | Typical Market Behaviour |
|---|---|---|---|
Asian Session | Low to moderate | May be wider | Often quieter in many major pairs |
London Open | High | Often tighter | Activity and volatility can increase |
London–New York Overlap | Very high | Often relatively tight | Higher activity and price movement |
Late US Session | Lower | May widen | Activity often declines |
These are general characteristics rather than fixed rules. Liquidity, spreads and volatility vary by currency pair, broker and market conditions.
What Happens During Off-Peak and Rollover Hours?
The 24-hour forex market gives traders flexibility, but finding the best time to trade forex means recognising that quieter periods can bring less favourable execution conditions.
When fewer market participants are active, available liquidity may fall. Bid and ask prices can move further apart, while reduced market depth can make execution more sensitive to sudden changes in order flow.
For a retail trader, this can mean entering a position at a wider spread or receiving a different execution price from the one expected. These effects are generally more relevant in less liquid currency pairs and during unusually quiet or volatile market conditions.
Spread Widening and Slippage
Liquidity often declines as North American trading winds down and before activity builds again in the next trading day.
During periods of lower liquidity, spreads may widen. The effect can be more noticeable in minor and exotic currency pairs, which generally trade less actively than major pairs.
Lower market depth can also increase the risk of slippage. Slippage occurs when an order is executed at a different price from the one requested because the market moves before the order can be filled.
The spread alone therefore does not always represent the full cost of entering and exiting a trade.
Daily Rollover and Overnight Fees
A position that remains open beyond a broker's daily rollover time may incur an overnight fee, sometimes called a swap or financing charge.
The amount depends on factors such as the currency pair, trade direction, applicable interest rates and the broker's pricing structure. Depending on these factors, the overnight adjustment may be a charge or a credit.
Traders holding positions for more than one trading day should therefore consider financing costs alongside spreads and commissions.
Potential Trading Costs = Spread + Commission + Overnight Fees + Slippage
Not every trade will involve all of these costs, and the amount can vary considerably between brokers and market conditions.
Which Forex Trading Session Suits Your Strategy?
There is no single best time to trade Forex for everyone. The most suitable period depends on the currency pair, strategy, holding period and tolerance for volatility.
Scalpers and Day Traders
Short-term traders often focus on periods of higher liquidity, including the London session and London–New York overlap.
Tighter spreads can be particularly relevant to strategies targeting small price movements. However, greater activity can also mean faster price changes, especially around economic announcements.
Swing and Position Traders
Swing and position traders generally hold trades for longer, so small intraday changes in spreads may have less influence on their overall approach.
They may instead focus on broader price trends, technical levels and fundamental developments. Overnight financing is also more relevant because positions can remain open for several days or longer.
What Happens During Major Economic Announcements?
Important economic releases can produce some of the fastest price movements of the trading day. Examples include inflation data, employment reports and central bank interest rate decisions.
Spreads may widen and slippage can increase immediately before or after an important announcement as market participants adjust their orders and available liquidity changes.
Leverage makes these movements particularly important. It increases exposure to price changes and can increase both potential profits and losses. A relatively small market movement can therefore have a much larger effect on the capital committed to a leveraged position.
How Can You Manage Risk During Active Forex Sessions?
Trading during a liquid period can help reduce some transaction costs, but it does not reduce the underlying market risk.
Before opening a position, consider:
- the current spread;
- any broker commission;
- the possibility of slippage;
- overnight financing if the position may remain open;
- upcoming economic announcements; and
- the amount of leverage being used.
The London–New York overlap can provide high liquidity and active price movement, but that doesn't automatically make it the best period for every trader or strategy.
When comparing execution and fee structures between platforms, our CFD broker reviews provide more information on spreads, commissions and other trading costs.
Analysis cited by the European Securities and Markets Authority (ESMA) found that 74–89% of retail CFD accounts typically lost money across the EU jurisdictions examined. This historical figure should not be treated as the current loss rate for every CFD provider. Under rules from the Financial Conduct Authority (FCA), firms marketing, distributing or selling CFDs to UK retail clients must disclose an up-to-date, firm-specific percentage showing how many of their retail client accounts lose money.
Session timing can help traders judge the best time to trade forex, based on likely liquidity, volatility and trading costs — but it can't remove market risk.
Risk warning: This article is for educational purposes only and does not constitute financial advice. CFDs are complex, leveraged products and involve a high risk of losing money rapidly. Leverage can increase both potential profits and losses. Trading costs, spreads and execution conditions vary between brokers and market conditions.
FAQ
What Is the Best Time of Day to Trade Forex?
The London–New York overlap is generally one of the most active times to trade Forex. It typically occurs around 13:00–16:00 UTC, although times can shift with daylight-saving changes. With European and North American markets open simultaneously, major currency pairs often experience higher liquidity and relatively tight spreads.
Which Forex Session Has the Highest Trading Activity?
The London session is one of the busiest periods in the global forex market. According to the BIS 2025 Triennial Survey, UK sales desks accounted for 38% of global FX turnover in April 2025. Activity can increase further when London and New York are open at the same time.
What Are the Least Active Times to Trade Forex?
Forex trading tends to become quieter as North American trading winds down and before activity builds again in the next trading day. Major holidays can also reduce market participation. Lower liquidity may result in wider spreads and a greater risk of slippage, although conditions vary by currency pair, broker and market environment.
Does Liquidity Affect Forex Trading Costs?
Yes. Higher liquidity can contribute to tighter bid-ask spreads because more buyers, sellers and liquidity providers are active in the market. Lower-liquidity periods may have wider spreads and a greater risk of slippage. Actual trading costs depend on the currency pair, broker and market conditions.
Should I Trade Forex Around Major Economic News Releases?
Major economic releases can cause sharp price movements, wider spreads and increased slippage. Events such as US employment data, inflation releases and central bank interest rate decisions can create particularly volatile conditions. Whether to trade during these periods depends on your strategy and risk tolerance, but the additional execution risk should be considered carefully.
