Forex Trading Sessions: Sydney to New York Hours in GMT

The four main forex trading sessions are Sydney, Tokyo, London and New York, and together they keep the market open from Sunday at 5 p.m. to Friday at 5 p.m. New York time. This guide gives each session in GMT and New York time for both halves of the year. It also explains the overlaps, the weeks when daylight saving throws the usual times out, and how to read all of it on your MT5 clock.

What Are the Forex Trading Sessions?

Forex trading sessions are the blocks of the day when banks and dealers in a major financial centre are most active. Spot forex has no central exchange and no official opening bell, so session times are market conventions, and different sources list them about an hour apart.

People who trade currency pairs use sessions to judge when a pair is likely to be active and when spreads are likely to be tight. The table uses the convention most platforms follow, with winter running from early November to mid-March and summer from late March to late October, northern-hemisphere style.

Tokyo is the only session that keeps fixed GMT hours, because Japan does not use daylight saving. For a live picture, the Investing.com forex market hours map shows which centres are open at any moment.

When Does the Forex Market Open and Close?

The forex market opens for the week at 5 p.m. New York time on Sunday and closes at 5 p.m. New York time on Friday. In GMT that is 22:00 during US standard time and 21:00 during US daylight saving, and retail platforms usually take a short break around each daily rollover.

Five o'clock in New York also marks the end of each trading day, which is when overnight swap is applied and when spreads often widen for several minutes. Sunday's open is usually the thinnest moment of the week, and prices can gap away from Friday's close. Neither period is a good time to place a tight stop.

Weekends are closed for spot forex on retail platforms, though cryptocurrency CFDs may continue to trade where offered. Check the Sessions section of the MT5 Specification window for any symbol, because individual instruments have their own trading and quote hours.

What Happens in Each Forex Session

Each forex session has its own character, driven by which banks are at their desks and which economic data is being published. The Bank for International Settlements' 2025 survey shows how uneven that activity is, with the United Kingdom handling 37.8% of global turnover and the United States 18.6%.

Sydney Session

The Sydney session opens the week and is normally the quietest of the four, with thinner liquidity and often wider spreads. AUD/USD, NZD/USD and AUD/NZD see most of the attention, and Australian and New Zealand data can move those pairs sharply despite the low overall volume.

Tokyo Session

The Tokyo session brings in Japanese banks and exporters along with other Asian centres. The BIS survey puts Japan at 3.5% of global turnover and Singapore at 11.8%, so a large share of Asian trading actually happens outside Tokyo. USD/JPY, EUR/JPY and AUD/JPY are the most active pairs, and many majors move in narrow ranges.

London Session

The London session is the largest of the four and often sets the direction of the day. EUR/USD, GBP/USD, EUR/GBP and USD/CHF are most active, and the first hour frequently breaks out of the range built overnight. The 4 p.m. London benchmark fix can also produce a burst of volume late in the session.

New York Session

The New York session brings the major US data releases, and the Bureau of Labor Statistics publishes Non-Farm Payrolls at 8:30 a.m. New York time, usually on the first Friday of the month. That is 13:30 GMT in winter and 12:30 GMT in summer. Activity falls away after London closes, and the last hours before 5 p.m. tend to be slow.

Central Bank Announcements by Session

Central bank decisions fall in predictable places on the session map. The Bank of England usually publishes at 12:00 London time and the European Central Bank at 14:15 Frankfurt time, so both land during London hours. The Federal Open Market Committee releases its decision at 2:00 p.m. New York time, which is 19:00 GMT in winter and 18:00 GMT in summer, after London has closed and liquidity has already thinned.

How to Measure a Session Range on MT5

Session descriptions are generalisations, so measure the pair you actually trade. Open an H1 chart, mark the start and end of each session with vertical lines, and record the high-to-low range of each block for the last 20 trading days. An average takes about half an hour to build by hand, and it replaces opinion with a number.

Suppose your 20-day log shows a pair averaging 25 pips in the Tokyo block, 55 pips in London and 45 pips in New York. A 30-pip target taken during Tokyo would need more than the whole average session, while the same target during London is roughly half of a normal block. Those figures are hypothetical, and yours will change with volatility, so refresh the log every few months.

Forex Session Overlaps in GMT

Forex session overlaps are the periods when two major centres are open together, and the London and New York overlap is the busiest of them. That overlap runs from 13:00 to 17:00 GMT in winter and 12:00 to 16:00 GMT in summer, which is 8 a.m. to 12 p.m. in New York.

More liquidity does not mean smoother price action, because the same window holds the US data releases. Spreads on the majors tend to be tightest here, but moves can be fast and a stop placed for quiet conditions may be too close. Reduce size around scheduled data if your system was built on calmer hours.

How Daylight Saving Shifts the Forex Sessions

Daylight saving shifts forex sessions because the United States, the United Kingdom and Australia change their clocks on different dates, and Japan does not change at all. For a few weeks each spring and autumn, the usual gap between London and New York is four hours rather than five.

The United States moves clocks forward on the second Sunday of March and back on the first Sunday of November. The United Kingdom changes on the last Sunday of March and the last Sunday of October, and New South Wales moves forward on the first Sunday of October and back on the first Sunday of April, the opposite way round. Applying those current rules to 2027 gives the dates below.

The Weeks When the Overlap Runs Five Hours

Most session tables skip the mismatch weeks entirely. Between 14 and 28 March 2027, and again between 31 October and 7 November 2027, New York is on daylight time while London is on GMT. New York's day therefore starts at 12:00 GMT while London still closes at 17:00 GMT, so the overlap runs five hours instead of four.

US data arrives an hour earlier for anyone working from London time during those weeks. Non-Farm Payrolls lands at 12:30 London time rather than 13:30, and traders have been caught out by automated strategies coded to a fixed clock. Check any Expert Advisor with hard-coded hours before those dates.

Forex Trading Hours on Holidays

Forex trading hours on holidays usually stay open, but liquidity falls sharply when a major centre is closed, and instruments linked to closed exchanges may stop trading early. Christmas, New Year's Day, Japan's Golden Week and US Thanksgiving are classic periods of thin trading and wider spreads.

A regulated forex broker will normally publish its holiday schedule in advance, because symbol sessions can change even when spot forex keeps trading. Brokers set their own holiday hours, so times differ between firms and from one year to the next. Always use your own broker's notice rather than a general calendar.

Thin holiday markets can produce large moves on small orders. A stop that survives ordinary conditions may be triggered by a brief spike, and positions held across a holiday still pay or receive swap. Many traders simply reduce size for the week around Christmas and New Year.

How to Read Forex Sessions on Your MT5 Clock

To read forex sessions on your MetaTrader 5 (MT5) clock, compare the server time at the top of Market Watch with GMT. Many brokers set the server to GMT+2 in winter and GMT+3 in summer, which keeps the London and New York sessions at the same clock times all year.

On an MT5 account such as Tradin's, server time is GMT+2, or GMT+3 during daylight saving. That setup ends each daily candle at 5 p.m. New York time, so the sessions map neatly on to the chart. The table shows how the hours appear on a server of that type.

Only Tokyo moves on that kind of server, which makes it far simpler than converting from GMT each season. During the mismatch weeks London appears an hour later on the chart, at 11:00 to 20:00 on a server that has already moved with the US. To convert to your own time, find your offset from GMT: a trader in Dubai at GMT+4 sees the New York open at 17:00 in winter and 16:00 in summer.

Which Forex Session Is Best for Your Trading Style

The best forex session depends on the pair and the trading style, since scalpers need tight spreads and range traders need quiet conditions. Most traders do best by picking one session that fits their daily schedule and learning its normal behaviour, rather than watching the screen for all 24 hours.

Sessions apply beyond currencies. In commodities trading, gold is usually most active during London and New York hours, and oil reacts to the US inventory data published during the New York morning. Index CFDs follow the cash hours of their home exchange, so check the session list before assuming a market is open.

Forex Session Questions Traders Ask Next

Traders learning the forex sessions usually ask next whether the market truly runs 24 hours, which session moves the most, what the best time is for a beginner, and whether Monday or Friday behave differently. The short answers depend on liquidity, which rises and falls with each regional handover.

Is the Forex Market Really Open 24 Hours?

The forex market trades continuously for 24 hours a day on weekdays, but liquidity is far from constant. There is a short daily pause on most retail platforms around 5 p.m. New York time, and activity differs greatly between the London morning and the hours just after the New York close.

Which Forex Session Has the Most Volume?

The London session has the most volume, and the United Kingdom's 37.8% share of global turnover in the BIS 2025 survey is about double the US share. The London and New York overlap is where the two largest centres trade together.

What Is the Best Forex Session for Beginners?

Beginners usually do best in the first half of the London session or the London and New York overlap, when spreads on the majors are tight and price tends to respect levels. Avoid the first minutes after a major data release, and keep position sizes small while learning how fast these periods can move.

What Is the Best Day of the Week to Trade Forex?

Tuesday to Thursday usually offer the most consistent conditions, because Monday's Asian hours start thin and Friday afternoon fades as traders close positions before the weekend. Friday mornings can still be busy, particularly on Non-Farm Payrolls days. Check your own trade log before treating any weekday as better than another.

Should You Hold Trades Through the Session Close?

Holding through the New York close means paying or receiving swap and accepting a spike in spreads, which can touch a tight stop. A position that needs a very small stop is better closed before 5 p.m. New York time, while a swing position with room to breathe can usually sit through it.

Learn One Session Well

Pick the session that fits your day and matches the pairs you trade, then write its opening and closing times in your own time zone and in server time. Recheck those times in March, October and November, when the clock changes move the sessions without any notice on your chart.
