Trading sessions and market hours

A global trading week

The forex market operates through a global network of banks and other participants rather than one central exchange. Trading generally runs around the clock from Sunday evening to Friday evening in UTC, as activity passes between financial centres. Exact opening and closing times depend on the instrument and broker schedule. Public holidays can also affect availability, so “24 hours a day” does not mean uninterrupted access to every instrument.

Forex hours should not be confused with the hours of every CFD available on a platform. Gold, stock indices and share CFDs can have different schedules, including daily breaks or hours linked to an underlying exchange. A symbol appearing in MT5 does not necessarily mean it is currently tradable. Check its trading sessions and any holiday notices rather than assuming that all markets follow the forex week.

The main forex sessions

The trading day is commonly divided into the Sydney, Tokyo, London and New York sessions. These labels describe periods associated with major financial centres; they are not official opening bells for the whole forex market. Sydney and Tokyo represent much of the Asia-Pacific trading day, followed by London and then New York. Because these periods overlap, participation changes gradually rather than switching instantly from one region to another.

Activity in a currency pair can be influenced by which financial centres are active and when relevant economic news is released. For example, Japanese announcements may affect yen pairs during Asian hours, while US announcements may affect dollar pairs during New York hours. These are patterns of participation, not rules about price direction. An unexpected event can move a market during any session, including a usually quieter period.

Overlaps and trading conditions

An overlap occurs when two major sessions are active at the same time. The London–New York overlap is often associated with greater participation in major forex pairs. More participation can support liquidity: the ability to buy or sell without strongly affecting the price. Spreads, the difference between bid and ask prices, may be narrower in liquid conditions, but this is not guaranteed and can change quickly around news.

Volatility describes how much and how quickly prices move; it is not the same as liquidity. A busy session can still experience sharp movements, wider spreads or slippage, where an order executes at a different price from the expected price. Quieter periods, daily rollover and market reopenings may also bring less favourable execution conditions. CFDs are leveraged products and carry a high risk of loss, so an active session should never be treated as a safe session.

Worked example: converting session times

Consider a hypothetical session calendar for a particular week. It lists London as 08:00–17:00 UTC and New York as 13:00–22:00 UTC. Their overlap begins at the later opening, 13:00, and ends at the earlier closing, 17:00. The overlap therefore lasts four hours. For a learner whose local time is UTC+3 that week, adding three hours converts the overlap to 16:00–20:00 local time.

These example hours are not a permanent trading schedule. Daylight saving changes can shift session times relative to UTC, and countries do not all change their clocks on the same date. Your local clock may change too. If the hypothetical New York session shifted one hour earlier while London stayed unchanged, the overlap would become 12:00–17:00 UTC, lasting five hours. Always use a calendar for the relevant date and verify the instrument’s actual trading hours separately.

Check hours in MT5

In the desktop version of MT5, find the instrument in Market Watch, right-click it and open Specification. Review the displayed trading sessions and relevant contract details. Also check which time zone the broker uses for its schedule and chart timestamps; do not assume they match your local clock. Broker notices are important because holidays or exceptional events may alter the normal timetable.
