Forex Market Hours: Best Times to Trade and How Holidays Affect Trading

The forex market is often described as a market that never sleeps, but that description is only partly true. It runs around the clock during the trading week, yet it does not behave the same way at every hour. At some times, prices move quickly and spreads are tight. At others, the market is slow, thin and hard to read. Knowing when the market is open, and when it is most active, can help you choose better moments to trade and avoid conditions that do not suit your strategy. In this guide, we explain forex market hours, the four main sessions, the best times to trade and what to expect around holidays.

When is the forex market open?

Forex trades five days a week. The week begins on Sunday evening in GMT terms, when trading starts in Sydney and New Zealand, and it ends on Friday evening, when the New York session closes. Over the weekend, the main markets are closed, which is why prices can open with a gap on Sunday evening if news arrived while the market was shut.

Because forex is not run from a single exchange, trading passes from one financial centre to the nextas the day moves around the world. This is what creates the trading sessions. The exact opening and closing times shift by about an hour during the year, because the United Kingdom, Europe and the United States change their clocks on different dates. For that reason, it is wise to check current times rather than relying on a fixed schedule.

The Four Main Trading Sessions

The times below are approximate and are shown in GMT. They are a useful guide, not a strict rule.

The Sydney session runs roughly from 22:00 to 07:00 GMT. It is usually the quietest of the four, with lower volume. Currency pairs involving the Australian and New Zealand dollars tend to be the most active during this period.

The Tokyo session runs roughly from 00:00 to 09:00 GMT. It is the main session for Asian traders. The Japanese yen is the star here, so pairs such as USD/JPY and EUR/JPY often see more movement. Ranges are generally moderate, and the market can move sideways for long periods.

The London session runs roughly from 08:00 to 17:00 GMT. It is the largest in terms of volume, because London is a major centre for currency trading. The euro and the British pound are very active, and many strong trends begin or accelerate in this session.

The New York session runs roughly from 13:00 to 22:00 GMT. It is the second largest, and activity is driven by the US dollar and by important economic releases from the United States. The early part of the session, when it overlaps with London, is typically the most energetic.

Session overlaps: when the market is busiest

The most active periods come when two sessions are open at once. The overlap of London and New York, roughly from 13:00 to 17:00 GMT, is usually the busiest time of the trading day. Volume is high, spreads are often tight and prices move more, which creates more opportunities, and also more risk.

The overlap of Tokyo and London, roughly from 08:00 to 09:00 GMT, is short but can bring a burst of movement in pairs such as EUR/JPY and GBP/JPY. The overlap between Sydney and Tokyo happens in the early hours and tends to be modest.

The best times to trade by pair

A good rule of thumb is to trade a currency pair when the countries behind its currencies are awake. EUR/USD and GBP/USD tend to be most active during London and the London and New York overlap. USD/JPY is often busy during both the Tokyo session and the New York session. AUD/USD and NZD/USD tend to see more action during the Sydney and Tokyo hours, and also when US data is released.

Converting session times to your local time

Most traders do not live on GMT, so it helps to convert the sessions to your own time zone. As an example, a trader in a location that is eight hours ahead of GMT would see the London and New York overlap between about 21:00 and 01:00 local time. A trader in a location three hours ahead of GMT would see it between about 16:00 and 20:00.

You can use a simple method. Take the GMT time of the session, add or subtract your time zone difference and then adjust by one hour if daylight saving time is in effect in the relevant market. A world clock tool or a market hours table can save time and reduce errors.

Watch the server time on your platform

Another point that confuses many beginners is that trading platforms usually display the broker's server time, not your local time. The clock on your chart may therefore be several hours different from the one on your wall. This matters when you plan trades around news or sessions, or when you use an indicator that depends on time.

On MetaTrader, you can check the server time in the Market Watch window, which shows the time of the latest price update.

Quiet hours and the rollover period

Not every hour is good for trading. The period between the New York close and the Tokyo open, often called the rollover period, tends to have thin liquidity. Spreads can widen sharply, and small orders can move prices more than usual. Many traders avoid opening new positions during this window, particularly with tight stop losses.

Friday afternoons can also be tricky. As the week closes, traders reduce their positions, and some prefer not to hold trades over the weekend because of the risk of a gap. Sunday evening openings can bring wider spreads for the same reason.

How holidays affect trading hours

Forex does not shut down for most holidays, but trading conditions can change. When a major financial centre is closed, such as the United States on Independence Day or Thanksgiving, or the United Kingdom on a bank holiday, liquidity drops. Spreads can widen, prices can jump on small volumes and some instruments may close early or have limited hours.

Around year end, thin markets are common, and trading hours for some products, such as indices and commodities, can change. Before you plan trades around a public holiday, check the schedule for the instruments you trade. You can find the latest information on the Holiday Trading Hours page.

How to choose your trading window

The best time to trade is the one that fits both the market and your life. Start by choosing the pairs you want to trade and look at when they are most active. Then see which of those hours you can actually watch. A trader who works during the day may prefer the evening overlap, while a night owl may enjoy the Asian session.

It is better to focus on one or two sessions than to try to trade around the clock. Constant screen time leads to tiredness and mistakes. Many successful traders trade only a short window each day, when conditions suit their strategy, and stay out of the market the rest of the time.

Keep a journal of your trades with the time of day recorded. After a few weeks, you may find that your results are better in certain hours. That information is far more valuable than any general rule.

Economic news and timing

Session hours are only part of the story. Major economic releases, such as the US non farm payroll report, inflation figures and central bank decisions, can cause sharp moves at specific times regardless of the session. Check an economic calendar each day, note the times in your local zone and decide in advance whether you will trade around those events or stay aside.

Final thoughts

The forex market is open around the clock from Sunday evening to Friday evening, but its activity moves in waves as the Sydney, Tokyo, London and New York sessions open and close. The busiest period is usually the London and New York overlap, while the rollover period is often quiet and costly. Learn the sessions in your own time zone, check the platform's server time, watch for holidays and choose a trading window that suits your strategy and your schedule.
