Forex trading normally runs around the clock from Sunday evening to Friday evening in New York time. Within that week, activity moves through Sydney, Tokyo, London and New York, with overlapping business hours rather than a single opening bell.
The useful question is not just whether the market is open. It is whether your currency pair has suitable trading conditions, whether news is due, and whether your platform’s clock matches the session you intend to trade. An open market is not an instruction to place an order.
When Does the Forex Market Open and Close?
A common reference for the forex week is 5:00 p.m. Sunday to 5:00 p.m. Friday, Eastern Time. The institutional Cboe FX trading schedule uses these hours. Retail brokers may open slightly later, close earlier or introduce maintenance breaks, so their instrument schedules determine when you can actually trade.
At 5:00 p.m. New York time, the UTC clock reads 22:00 during Eastern Standard Time and 21:00 during Eastern Daylight Time. A fixed claim that forex always opens at “22:00 GMT” therefore misses the seasonal change.
For a trader in the United States, the opening falls on Sunday afternoon or evening. In much of Asia and Australia, it is already Monday. These are different calendar dates for the same trading week, not separate market openings.
Forex Trading Sessions in UTC and Local Time
Session names describe broad periods of regional business activity. They are not regulated opening hours for four separate forex exchanges. The Australian Foreign Exchange Committee’s trading-hours guidance confirms that foreign exchange has no set daily trading hours.
The table below uses practical session windows. Read each row using that city’s own clock status: Sydney’s daylight saving season does not match London’s or New York’s.
| Session | Local business-hour window | UTC during local standard time | UTC during local daylight saving time |
|---|---|---|---|
| Sydney | 08:00 to 17:00 | 22:00 to 07:00 next day | 21:00 to 06:00 next day |
| Tokyo | 09:00 to 18:00 | 00:00 to 09:00 | No seasonal clock change |
| London | 08:00 to 17:00 | 08:00 to 17:00 | 07:00 to 16:00 |
| New York | 08:00 to 17:00 | 13:00 to 22:00 | 12:00 to 21:00 |
Sydney’s UTC window starts on the preceding calendar date relative to its local business day. These session boundaries are approximate; a session indicator using a different opening convention can show a slightly different window without changing when your broker accepts orders.
Sydney moves its clocks forward on October 4, 2026, under the New South Wales daylight saving schedule. Using the table’s convention, its opening then shifts from 22:00 UTC to 21:00 UTC. This does not mean every retail platform moves its weekly opening with Sydney.
What to Watch During Each Session
Sydney and Tokyo: Check the Regional Calendar
For trading during Asia-Pacific business hours, start by checking events affecting the Australian dollar, New Zealand dollar and Japanese yen. USD/JPY, AUD/USD, NZD/USD and AUD/JPY are useful pairs to include in that review, but their currency names do not restrict when they can move.
Do not build a strategy around the assumption that “Asia always ranges.” Instead, separate ordinary sessions from sessions containing policy decisions or major economic releases. A range strategy tested on uneventful days does not automatically suit a central bank announcement.
Equally, trading AUD/USD does not require trading during Australian office hours. The US dollar side of the pair still matters, and a trader who can only monitor New York should test that window rather than force an overnight routine.
London: Treat the Opening as a Review Point
Use the start of London business hours to reassess positions and price levels established earlier in the day. For EUR/USD and GBP/USD, that means checking the European and UK calendar before deciding whether an apparent breakout deserves attention.
A session opening can be part of a trading rule, but it is not a complete rule. Define what confirms an entry, what invalidates it and how much spread you will accept. Otherwise “trading the London open” becomes a rather formal name for clicking at eight o’clock.
New York: Watch Events, Not Just the Clock
The New York forex session should not be confused with the US stock market’s opening. Currency trading is already underway before the cash equity session begins. The Bureau of Labor Statistics Employment Situation schedule, for example, lists releases at 8:30 a.m. Eastern Time.
If your trading window includes a release, decide beforehand whether your plan permits holding positions through it. Waiting until the price starts moving leaves little room for a considered decision.
How Daylight Saving Changes Forex Market Hours
UTC does not change seasonally, but local business clocks do. This distinction matters when converting a session into your own time zone or setting an alert that repeats every weekday.
In New York, daylight saving began on March 8, 2026, and ends on November 1, 2026, under the US daylight saving schedule published by NIST. Use “ET” when referring to New York time throughout the year. “EST” means the standard-time offset, not every version of Eastern Time.
London follows different transition dates. British Summer Time began on March 29, 2026, and ends on October 25, 2026, under the UK government’s clock-change timetable. Consequently, London and New York are four hours apart during the mismatch periods rather than their usual five.
For trading weekdays in 2026, those mismatch windows are March 9 to March 27 and October 26 to October 30. A London opening that normally appears at 3:00 a.m. New York time appears at 4:00 a.m. during those periods.
Use a calendar or session clock that converts named locations for the selected date. A permanent “subtract five hours” shortcut works until it does not, usually on the morning you were expecting it to save time.
The London–New York Overlap
The overlap is the period when both London and New York business-hour windows are active. Historical RBA research on intraday AUD/USD trading found higher turnover and volatility during this period. That supports paying attention to the overlap, not assuming it guarantees better trades.
Using the session conventions above, the overlap runs from 13:00 to 17:00 UTC when both cities use standard time, and 12:00 to 16:00 UTC when both use daylight saving time. Both correspond to 8:00 a.m. to noon in New York.
During the US–UK clock-change mismatch, the calculated overlap becomes 12:00 to 17:00 UTC, or 8:00 a.m. to 1:00 p.m. New York time. The extra hour comes from different clock settings, not an extension announced by a forex exchange.
Other overlaps matter too. The table gives Sydney and Tokyo a shared window of 00:00 to 07:00 UTC during Sydney standard time, or 00:00 to 06:00 during Sydney daylight saving. Tokyo and London overlap from 08:00 to 09:00 UTC in UK standard time, or 07:00 to 09:00 during British Summer Time.
Use these windows to organize research, then check actual conditions. Liquidity, price movement and trading opportunity are different things. A busy session can still produce an unsuitable entry, especially around an announcement. The guide to how economic news affects currency prices covers that event risk separately.
Rollover, Spreads and the Daily Trading Boundary
The period around the New York close deserves its own check. Liquidity can thin during the transition into the next trading day, and spreads can widen. A platform showing live prices does not guarantee that dealing costs resemble those available earlier in the session.
Retail financing adjustments are commonly associated with a daily rollover cutoff around 5:00 p.m. New York time, although the exact cutoff and treatment depend on the broker and instrument. Holding a position for only a few minutes does not necessarily avoid financing if those minutes cross that boundary.
Keep the spread and financing separate in your calculations. One is part of the price of entering or exiting; the other concerns carrying the position across the applicable cutoff. The guide to forex spreads, commissions and swap charges explains those costs without treating every broker’s schedule as identical.
Consider a hypothetical strategy targeting a six-pip movement. A spread widening from 0.8 pips to 2.4 pips consumes a much larger share of that target, even if the chart setup looks unchanged. Those figures are illustrative, not typical quotes. The practical rule is to test costs during the hours you intend to trade.
Weekends, Holidays and Product Differences
Do not assume every product labelled “forex” follows the same schedule. Currency futures have exchange-defined hours. For example, CME’s FX futures schedule lists trading from 5:00 p.m. to 4:00 p.m. Central Time, Sunday through Friday, with a daily one-hour break. That is not the same timetable as continuous weekday spot dealing.
Before a holiday, check the schedule for your actual instrument and account. Look for an early close, delayed reopening or maintenance period rather than relying on a general forex clock. A public holiday in one financial center also does not establish a universal closure across every venue.
Weekend exposure requires a separate decision. News can arrive while your usual market is closed, and reopening prices can differ from Friday’s final quotes. An ordinary stop order does not guarantee execution at its trigger price if the market gaps through it. The guide to managing overnight and weekend risk addresses that problem in more detail.
Build a Trading Schedule You Can Actually Follow
Choose a monitoring window before choosing how many trades to make. If you can reliably watch the market for 90 minutes, test a plan for those 90 minutes. A strategy requiring attention through three sessions is not suitable simply because the market permits it.
Before each session:
- Confirm the date, local time conversion and broker trading hours.
- Check scheduled announcements affecting both currencies in the pair.
- Compare the current spread with the maximum allowed by your plan.
- Set a last-entry time and decide whether positions may remain open afterward.
Record the session alongside results, costs and execution quality. Also record whether the day contained a major announcement or clock-change mismatch. A profitable morning and a profitable strategy are not the same finding.
Use those records when building and testing a trading plan. The best forex trading hours for your approach are the hours supported by its rules, realistic costs and repeatable evidence—not whichever session happens to be open when you sit down.
