Forex Market Hours and Session Overlaps: How the 24-Hour Week Works
Learn what the 24-hour forex week means, how Sydney, Tokyo, London, and New York session conventions overlap, and why daylight saving and broker schedules matter.
In this guideWhat “24-hour forex” means
Short summary
Forex does not open and close to one exchange bell. Trading activity moves through financial centres, while the hours a broker offers its customers follow a separate schedule with product-specific breaks and holidays.
What “24-hour forex” means
The phrase usually describes a weekday handoff: activity starts in the Asia-Pacific region on Sunday evening and continues through Asia, Europe, and North America until Friday evening. It does not mean that every currency pair trades with the same depth every minute, or that trading continues normally throughout the weekend. A change in the date or a local holiday can affect which participants are active even while another region remains open.
There is no single global forex exchange. The Bank for International Settlements says FX activity takes place across multiple venues, with no single trading venue or single price. Interbank spot transactions, electronic platforms, exchange-listed currency futures, and a retail dealer’s platform have different structures. A market-hours chart is therefore a useful convention, not a universal opening notice that overrides an instrument’s contract or broker’s schedule.
For U.S. retail over-the-counter forex, the Commodity Futures Trading Commission describes customers as trading against their dealer, which sets the prices and conditions available on its platform. That is a U.S.-specific OTC warning, not a definition for every FX product worldwide. Exchange-listed currency futures follow their exchange’s session, maintenance breaks, and holiday calendar. Two products with “FX” in their names can have different trading hours.
The four hubs are reference windows
Sydney, Tokyo, London, and New York are commonly used to describe major centres of FX activity. A session is an approximate window associated with local business hours; it is not a universal exchange bell for all currency trading in that city. The table below converts commonly published session conventions to UTC for a standard-time example on February 3, 2026. It is not a live schedule for any broker.
| Activity centre | Example UTC window | A simple overlap reading |
|---|---|---|
| Sydney | 22:00–07:00 | Overlaps part of the Tokyo window |
| Tokyo | 00:00–09:00 | Overlaps Sydney and London windows |
| London | 08:00–17:00 | Sits between Tokyo and New York activity |
| New York | 13:00–22:00 | Overlaps London from 13:00–17:00 UTC |
These UTC windows are teaching conventions, not a global standard for when a session begins or ends. Local holidays, business customs, platforms, and contract terms affect actual quotes and execution. A window that crosses midnight may span two UTC dates, so check the date rollover as well as the clock time. OANDA’s session guide is one example of this convention.
An overlap is a chance for activity, not a promise
When the business hours of two centres overlap, more participants and information flows may be active at once. In the example above, Sydney and Tokyo overlap from 00:00 to 07:00 UTC, Tokyo and London from 08:00 to 09:00, and London and New York from 13:00 to 17:00. These windows are a starting point for observation; they do not guarantee a minimum level of liquidity or trading volume.
More activity can support liquidity, but it can also coincide with larger price changes. Central-bank decisions, inflation or employment releases, political news, and reduced participation around holidays can all affect quotes. A spread may widen or execution may become less predictable after a major release, even during a popular overlap. A pair may also be active outside its presumed “main” session because of local hedging flows or news.
Calling the London–New York overlap “the best time” leaves out the goal and the risk. Larger moves can increase losses as well as gains, and fast conditions may be poor for orders that need stable execution. A spread observed in one sample cannot be generalized to every broker, pair, order size, or volatility regime. Use session times to decide when to observe a market, not to forecast a result.
The currencies in a pair point to different regions
The countries and economic centres connected to a pair can help identify which local information to watch. AUD or NZD pairs may make Asia-Pacific releases and business flows relevant. JPY pairs call for attention to Tokyo hours and Japanese policy news. EUR and GBP pairs connect to London and wider European activity; CAD pairs may respond to North American data. These are prompts for checking context, not rules that a pair must move more or trade more cheaply during those hours.
Relationships between currency pairs are not fixed either. EUR/USD is not guaranteed to be active simply because it is European daytime, and every yen pair does not have a tight spread throughout Tokyo hours. Holidays, central-bank calendars, macroeconomic news, risk sentiment, and a broker’s liquidity providers can change what appears on screen. Review the relevant calendar, live bid and ask, quote updates, and your intended order size alongside the session label.
Convert by date and named time zone
To compare local times, choose a specific date and apply each centre’s time zone separately. On February 3, 2026, New York is on Eastern Standard Time (UTC−5), London on Greenwich Mean Time (UTC+0), Sydney on Australian Eastern Daylight Time (UTC+11), and Tokyo on Japan Standard Time (UTC+9). In this example, London’s 08:00 session convention is 08:00 UTC and 03:00 in New York. Writing the same clock number for both cities would misstate the overlap.
Daylight-saving transitions do not happen on the same dates everywhere. The United States and United Kingdom change clocks in spring and autumn; some Australian states change clocks during the opposite season; Japan does not use daylight saving time. During weeks when transitions are out of sync, UTC overlap windows can shift by an hour. “EST” used without distinguishing it from “EDT” can also confuse an international schedule.
For a conversion, pair a date with named zones such as America/New_York, Europe/London, Australia/Sydney, and Asia/Tokyo. The IANA time-zone database is updated when governments change civil-time rules, so do not keep reusing a fixed UTC offset indefinitely. Saving important releases in UTC and displaying them in your current location can reduce mistakes when clocks change.

A broker’s tradable hours can differ from the market convention
Customer access depends on the broker entity, account, product, currency pair, maintenance, and holiday schedule. For example, OANDA’s U.S. entity publishes hours for most FX products from Sunday 17:05 to Friday 16:59 New York time, with a daily six-minute break from 16:59 to 17:05 and additional exceptions for some pairs. That is a schedule for a specific provider and product, not a global rule. A different entity or an updated notice can change the hours available to a customer.
A displayed quote or the ability to submit an order while a market is closed does not mean an opening or closing trade will execute immediately. A provider may accept or let customers modify orders during a closure while position changes wait for the next session. Check the pair-specific hours, when orders actually become active, daily maintenance, platform time zone, order-expiry rules, and holiday exceptions in the account agreement and platform notices. Record the time zone and the date of the notice you used.
Weekends and holidays can bring gaps and thinner quotes
When trading is unavailable or quotes are sparse, you may not see the path a price took between two tradable observations. News over the weekend can leave the first quote at the weekly reopening different from Friday’s last quote. OANDA’s customer guidance says prices may change significantly at the reopening and orders can execute at the prevailing market rate; a stop can therefore fill at a different price from its trigger. This is a provider-specific warning, but it illustrates a general execution risk across noncontinuous sessions.
Financial centres do not all close for the same holidays. Even if one region remains open, fewer participants or liquidity providers can mean wider spreads or less depth than usual. “Forex is open 24 hours” does not promise identical price quality or execution throughout the week. If a position remains open through a weekend or holiday, account for possible gaps, margin requirements, financing, and order-duration rules separately.
Use the session chart to check the actual product
First identify whether the product is retail OTC spot/CFD or an exchange-listed currency future, and confirm the contracting broker entity and jurisdiction. Then record the pair’s weekly open and close, recurring daily breaks, holiday changes, server time zone, and the difference between order acceptance and execution. Compare the quotes and costs you expect during those hours; forex spreads and commissions and forex rollover financing cover separate cost components.
For a useful sample, keep the currency pair, approximate order size, UTC window, and date range consistent. If you can access your account’s quote history or execution confirmations, record timestamps, bid and ask, spread, fill price, order type, and whether a holiday or major release was underway. OTC prices and activity can differ by provider, so do not treat one broker app’s volume or quotes as a consolidated measure of all FX trading. BIS market-structure guidance notes that the market has neither one trading venue nor one price.
A session chart helps decide when to observe; it is not a signal of likely profit. Leverage and position size cannot be chosen from a timetable alone. See forex margin and leverage and forex lot size and pip value. For an exchange-traded currency product, futures session breaks and gap risk describes a different venue’s schedule. Always verify the provider’s latest product-specific hours before placing an order.
Common questions
Q1Is the forex market really open 24 hours a day?
The phrase usually means a 24/5 weekday convention, with activity handed across financial centres from Sunday evening to Friday evening. It does not mean weekend trading or continuous execution for every pair. Product and provider hours can differ.
Q2Is the London–New York overlap always the best time to trade?
No. Participation and price movement may increase, but volatility, spreads, and execution conditions can also worsen, especially around news. Check the pair, date, order size, and actual quotes.
Q3How does daylight saving change forex session hours?
The United States, United Kingdom, and parts of Australia change clocks on different dates, while Japan does not. UTC session overlaps can therefore shift seasonally; convert using a specific date and named time zones.
Q4Can I place an order in a broker app over the weekend?
Some providers accept or let customers modify orders during a closure, while opening or closing fills wait for trading to resume. Check pair-specific hours, order-duration rules, holiday exceptions, and reopening gap risk in the provider’s current notices.
