What Are Trading Hours? Global Market Schedules Explained
In this article
Trading hours are the specific periods when financial exchanges, OTC networks and broker platforms accept and execute market orders. While forex trades 24/5 across major regional sessions and cryptocurrencies operate 24/7, equity and commodity markets run on fixed exchange schedules with daily clearing breaks.
Trading hours are the times when financial markets are open for buying and selling. These hours vary depending on the market, the asset being traded and the platform used.
While forex trading runs 24 hours a day during the working week, stock exchanges follow fixed opening hours and cryptocurrency markets operate around the clock.
Knowing when markets open and close can help traders understand changes in liquidity, trading costs and execution conditions. Trading outside busy market hours may mean wider spreads, greater slippage and increased exposure to price gaps.
Key Takeaways
- Trading hours vary by market. Forex operates 24 hours a day, five days a week, while cryptocurrencies trade 24/7. Stock exchanges follow set opening and closing times.
- CFD trading hours may differ from exchange hours. Brokers can apply daily trading breaks or separate schedules for individual instruments.
- Session overlaps often bring higher liquidity. The London–New York overlap is one of the busiest periods for forex trading.
- Off-peak trading carries additional risks. Lower liquidity can lead to wider spreads, slippage and less favourable execution prices.
How Do Trading Hours Work Across Different Markets?
Financial markets follow different trading schedules depending on how and where their instruments are traded. Some operate through centralised exchanges, while others use global electronic networks.
Forex Trading Hours (24/5)
The foreign exchange (forex) market operates 24 hours a day, five days a week. Trading generally begins on Sunday evening UTC, as markets open in the Asia-Pacific region, and continues until Friday evening in New York.
Unlike a traditional stock exchange, forex operates through a decentralised over-the-counter (OTC) network. This allows trading activity to move between financial centres as their working days begin and end.
Shares and Stock Indices
Shares are primarily traded during the opening hours of their respective stock exchanges.
For example, the London Stock Exchange (LSE) and New York Stock Exchange (NYSE) each follow their own local schedules.
Some markets offer pre-market or after-hours trading. Index futures and CFDs may also be available outside regular exchange hours, although liquidity and spreads can differ.
Options trading hours generally follow the relevant exchange schedule, with extended sessions available for certain products.
Commodities
Commodity trading hours depend on the exchange and the instrument.
Gold, oil and other widely traded commodities often have extended electronic trading sessions, with short daily breaks.
For example, gold futures on CME Globex typically trade for around 23 hours a day during the trading week. However, XAU/USD trading hours on CFD platforms may differ between brokers.
Cryptocurrencies (24/7)
Cryptocurrency markets generally operate 24 hours a day, seven days a week, including weekends and public holidays.
However, individual exchanges and CFD providers may temporarily restrict trading for maintenance or other operational reasons.
Exchange Trading Hours vs CFD Platform Hours
Trading hours shown on a CFD platform do not always match the opening hours of the underlying market.
A Contract for Difference (CFD) allows traders to speculate on the price movement of an underlying asset without owning it.
CFD brokers set trading schedules for each instrument, which may include daily breaks, weekend closures or changes around public holidays.
During a scheduled trading break, a broker may stop accepting new orders or temporarily restrict changes to existing positions. The exact restrictions depend on the platform and instrument.
It's also worth checking your broker's daily rollover time. Positions held beyond this cut-off may incur an overnight fee, sometimes called a swap charge. Depending on the instrument and position, the adjustment may be a charge or credit.
These costs can add up when positions remain open for several days.
Major Global Trading Sessions and Market Overlaps
The forex market is commonly divided into four major trading sessions: Sydney, Tokyo, London and New York.
Each session reflects trading activity in a different financial region.
Trading Session | Approximate Hours (UTC) |
|---|---|
Sydney | 21:00–06:00 |
Tokyo | 00:00–09:00 |
London | 07:00–16:00 |
New York | 12:00–21:00 |
These are indicative session times. Actual UTC hours change seasonally in regions that observe daylight saving time. Tokyo does not observe daylight saving time.
Why Do Trading Sessions Overlap?
A trading session overlap occurs when two major financial centres are active at the same time.
The London–New York overlap is particularly important because both regions account for substantial forex trading activity.
During this period, higher participation can improve liquidity and help keep bid-ask spreads relatively narrow.
The spread is the difference between the price at which an instrument can be bought and the price at which it can be sold.
However, tighter spreads and faster execution are not guaranteed. Major economic announcements can cause sharp price movements and temporary increases in trading costs, even during busy sessions.
How Does Daylight Saving Time Affect Trading Hours?
Trading session times can shift in UTC when countries change their clocks.
For example, London operates on Greenwich Mean Time (GMT) during winter and British Summer Time (BST) during summer.
New York also changes between Eastern Standard Time (EST) and Eastern Daylight Time (EDT).
Because the UK and US change their clocks on different dates, the London–New York overlap can vary during the year. Check current session times rather than relying on a fixed UTC schedule.
How Trading Hours Affect Liquidity, Spreads and Execution
Market conditions can change considerably throughout the trading day.
Liquidity refers to how easily an instrument can be bought or sold without significantly affecting its price.
When more buyers and sellers are active, trading costs may be lower. When participation falls, spreads can widen and orders may be harder to fill at the expected price.
Market Period | Typical Liquidity | Main Trading Risks |
|---|---|---|
London–New York overlap | High | News-driven volatility and slippage |
Quieter trading periods | Lower or variable | Wider spreads and reduced order depth |
Weekend close and reopening | Limited or unavailable | Price gaps and uncertain execution |
Why Can Spreads Widen Outside Busy Trading Hours?
During quieter periods, fewer market participants may be available to buy or sell at a given price.
Liquidity providers may respond by widening spreads to account for the additional risk.
This increases the cost of opening or closing a position. Lower liquidity can also increase slippage, which occurs when an order is executed at a different price from the one requested. Slippage can be positive or negative, although adverse slippage increases trading costs.
What Happens When Markets Reopen After the Weekend?
A market gap occurs when the opening price differs sharply from the previous closing price, with little or no trading between those levels.
Weekend gaps can follow political developments, economic announcements or other unexpected events while a market is closed.
For example, a currency pair may reopen on Sunday at a significantly different price from Friday's close.
If the market moves beyond a stop-loss level, the order may be filled at the next available price rather than the intended stop price. The outcome depends on the order type and any guaranteed stop-loss protection provided by the broker.
This can result in a larger loss than expected.
Leverage adds further risk because it increases exposure relative to the margin required to maintain a position. It can increase both potential gains and losses, particularly when prices move sharply.
How to Manage Risk Around Trading Hours
Understanding trading schedules can help traders make more informed decisions about when to open, manage or close positions.
Before you place a trade, it's worth checking:
- Market opening hours: Confirm when the instrument is available for trading.
- Session liquidity: Consider whether the market is typically active or quiet.
- Trading costs: Review spreads, commissions and overnight fees.
- Economic announcements: Check for scheduled events that may increase volatility.
- Platform breaks: Be aware of maintenance windows and order restrictions.
- Weekend exposure: Consider how price gaps could affect open positions.
These checks can't remove trading risk, but they can help you understand the conditions your orders may be filled in.
Conclusion
Trading hours influence when markets are accessible and how trading conditions may change throughout the day.
For active traders, session overlaps can provide periods of greater liquidity, although volatility may also increase. Traders holding positions for longer need to consider overnight fees, scheduled market closures and weekend gaps.
Understanding these differences can help you assess trading costs and execution risks before placing an order.

FAQ
What are the main trading hours for global financial markets?
Forex trades 24 hours a day, five days a week, moving through the Sydney, Tokyo, London and New York sessions. Stock exchanges follow local business hours – for example, the New York Stock Exchange's regular session runs from 09:30 to 16:00 New York time (ET). Crypto markets trade 24/7, all year round.
Why do bid-ask spreads widen outside normal trading hours?
Outside the main sessions, fewer traders are active, so there's less liquidity. Liquidity providers widen spreads to cover the extra risk of filling orders when the market is quiet.
What happens to open positions when trading hours end?
Open positions stay open, but you usually can't change or close them until the market reopens. If you hold a position past your broker's daily rollover time, you may pay or receive an overnight swap, depending on the instrument and the direction of your trade. Holding over the weekend also exposes you to price gaps when the market reopens.
How do daylight saving time changes affect trading session times?
When the UK switches to British Summer Time (BST) and the US switches to Eastern Daylight Time (EDT), their sessions move by one hour in UTC terms. Because the two countries change their clocks on different dates, it's worth checking session times around each switch in spring and autumn.
Can you trade CFDs during daily broker maintenance breaks?
Usually not. Many brokers pause trading for a short daily break around their rollover time, often between 21:00 and 23:00 UTC depending on the time of year. During the break, you may not be able to open new trades or change pending orders. The exact rules depend on your broker and the instrument, so it's worth checking its trading schedule.
