Market hours tell you when an instrument is available for trading under a particular venue, product and provider schedule. The familiar phrase “24/5” is useful shorthand for broad weekday access in markets such as foreign exchange, but it should not be read as a guarantee that every product trades continuously from Monday to Friday.
Daily breaks, exchange sessions, holidays, daylight-saving changes and product-specific rules can all affect availability. A clear routine starts with the instrument's current specification rather than a generic global clock.
What 24/5 access means
In over-the-counter foreign exchange, trading moves across financial centres as the business day progresses. This creates broad access through much of the working week. The market is decentralised, however, so the exact opening, closing and rollover arrangements depend on the provider and its connected liquidity.
Exchange-traded products follow the timetable of their exchange or trading venue. Many electronic futures contracts trade for long sessions but include a daily maintenance break. Stock and index-related instruments may have a main cash session, an extended session or a derivative schedule that differs from the underlying exchange.
Continuous does not mean identical
Conditions can change across a long trading day. Participation, spreads and available depth may differ between regional sessions, around economic releases and near daily rollover. An instrument being open does not mean it will have the same liquidity or transaction cost at every hour.
The main time references
Trading information can use several clocks. UTC is a stable global reference and does not observe daylight saving. An exchange may publish times in its home zone. A trading platform may use a broker server time, while your device displays local time.
UTC, exchange, server and local time
- UTC provides a consistent reference for conversion.
- Exchange time governs a listed venue's published sessions.
- Server time timestamps quotes, bars and transactions in the platform.
- Local time is the time zone configured on your device.
A platform chart can add another layer. The timestamp assigned to a candle normally follows server time, so the daily candle boundary may differ from midnight in your location. The same price data can therefore appear in differently shaped daily bars on systems using different server cut-offs.
Scheduled economic data should be handled in the same way. Read the time zone printed by the official release calendar, convert the actual date and avoid reusing a saved local time after a clock change. Calendar alerts are helpful, but their settings and device time zone should still be checked.
Do not assume these clocks match. MetaTrader records pending-order and transaction times according to the broker's trading server. The server offset can differ from your location and may change under the provider's operating schedule.
How trading sessions overlap
Market commentary often refers to Asian, European and North American sessions. These labels describe periods when major regional centres are active; they are not one universal set of opening bells for the whole foreign exchange market.
Overlaps can bring more participants and more price updates, but they do not guarantee deeper liquidity in every instrument. Local holidays, unexpected news and the currency pair itself can matter more than the label attached to a session.
Instrument hours still control
A CFD referencing an exchange-traded market may follow hours set by the provider around the underlying venue. It may pause while the underlying market is closed or use a separate out-of-hours pricing method. Confirm the product specification before relying on a session chart.
Why daylight saving shifts local times
Daylight-saving time advances the local clock in jurisdictions that use it. UTC itself does not change. The practical complication is that countries start and finish daylight saving on different dates, while some do not observe it at all.
For part of the year, the time difference between London, New York, Auckland, Sydney, Tokyo or another centre can therefore shift by one hour. A release that usually appears at a familiar local time may temporarily move on your calendar.
A safe conversion method
- Identify the source time zone stated by the exchange, issuer or calendar.
- Convert that time to UTC for the relevant date.
- Convert from UTC to your local zone for the same date.
- Check whether either location changes clocks before the event.
- Confirm the platform's server time separately.
Use a date-aware time-zone tool rather than memorising fixed offsets. Government and exchange calendars are preferable for material deadlines.
Holidays, maintenance and special sessions
Weekend reopening also deserves separate attention. A market may resume at a price different from its final pre-close quote because information accumulated while normal trading was unavailable. A pending order can then execute under its order rules at an available price, not necessarily at the last Friday quote.
Exchange holidays can shorten sessions, delay openings or close products entirely. Providers may also schedule platform or pricing maintenance. A holiday in one financial centre can reduce participation even when another centre remains open.
CME Group, for example, publishes annual holiday schedules and identifies daily breaks for its products. These schedules can be revised, so saved calendars should be rechecked near the date.
What session changes can affect
Session boundaries also affect order planning. A day order may expire at the end of the venue trading day, while a good-till-cancelled order may continue under the provider rules. Stop Loss and Take Profit instructions remain subject to market availability and execution conditions. If a market closes before a protective order can execute, the next available price may be beyond its trigger level.
Charts can make a closure look like a flat price rather than an unavailable market. Check whether quotes are live, delayed or paused before interpreting a stationary screen. The absence of a price update is not evidence that the market risk has stopped, particularly when another related venue remains open.
A closed or thin market can widen spreads, reduce available quantity and increase the chance of a gap when trading resumes. Pending orders may remain active according to their expiry settings, but they cannot force execution while no eligible price is available.
Overnight positions may also cross the provider's rollover time and incur financing. Our guide to overnight financing, swaps and triple-swap days explains how that separate cost layer works.
A practical pre-trade checklist
- Open the current contract or product specification.
- Check the normal session and any daily break.
- Review the exchange and provider holiday notices.
- Confirm the time zone attached to each published time.
- Convert the event for the actual calendar date.
- Check pending-order expiry and rollover settings.
- Allow for different liquidity around opens, closes and breaks.
The forex market overview provides broader context for weekday currency trading. For platform-specific timing, review the MetaTrader 5 workspace and the current instrument specification available to your account.
If a schedule is unclear, avoid treating a commonly quoted session time as permission to trade. Product availability and current platform status take priority over a general market convention.
Repeat the check when the account route or provider changes. A familiar instrument name can still have a different session, maintenance window or holiday treatment in another execution environment.
The schedule that matters most
Global session maps are useful for orientation. The schedule that governs an order is the current schedule for the exact instrument, account and platform route. Recheck it when clocks change, around public holidays and before holding a position across a daily break.
