How it works
The forex market passes from one region to the next through the week. This tool shows the four conventional sessions as a timeline in your local time, highlights the ones open right now and counts down to the next change.
Each session is defined in its own city's local time and converted with IANA time zones, so daylight saving time is applied automatically:
- Sydney: 07:00–16:00, Australia/Sydney time
- Tokyo: 09:00–18:00, Asia/Tokyo time
- London: 08:00–17:00, Europe/London time
- New York: 08:00–17:00, America/New_York time
For a full table of opening and closing times, see Forex Market Hours.
Formula
Session open now = (current time ≥ session start) and (current time < session end), with start and end converted from the city's local time to yours.
Overlap = the period from the later of two session starts to the earlier of the two session ends, if that period is longer than zero.
What each session tends to be like
These are general tendencies, not rules. Conditions change with news, holidays and the wider market mood.
Sydney
The trading week effectively begins as Asia-Pacific centers open. Activity is often lighter, and the Australian and New Zealand dollars are commonly in focus. Monday's open can show a gap from Friday's close if news arrived over the weekend.
Tokyo
Tokyo is the main Asian center in the conventional four-session model. The Japanese yen and Asia-Pacific currencies tend to be active, and Japanese economic releases fall in this window.
London
London is the largest forex trading center in the world, according to the BIS Triennial Survey. The European session often brings a clear pick-up in volume and volatility, with EUR, GBP and CHF pairs especially busy.
New York
The New York session overlaps with London for several hours, a window that typically has strong participation. Many important US economic releases are scheduled during New York morning hours.
Worked example: finding the overlap
Assume it is northern winter. In UTC, London runs 08:00–17:00 and New York runs 13:00–22:00.
- Later start = 13:00 (New York)
- Earlier end = 17:00 (London)
- Overlap = 13:00–17:00 UTC, which is 4 hours
If you live in a UTC+5:30 time zone, that overlap is 18:30–22:30 your time. In northern summer, both cities move their clocks forward, so the overlap is 12:00–16:00 UTC, or 17:30–21:30 in UTC+5:30.
Tips
- Pick sessions that fit your life. Consistency matters more than chasing the busiest hour.
- Expect wider spreads at quiet times, such as the late New York afternoon and around the daily rollover. See Liquidity.
- Check scheduled events. The Economic Calendar shows upcoming central bank meetings.
- Learn the background in Forex trading sessions.
Risk note
Session patterns describe typical behavior; they do not predict price direction. Sudden news can produce sharp moves at any hour, and markets can gap when they reopen. Trading carries a substantial risk of loss, and this tool is for education only.
Frequently asked questions
What are the four forex sessions?
Sydney, Tokyo, London and New York. Each is named after a major financial center and covers that city's typical business hours.
What is a session overlap?
An overlap is a period when two sessions are open at once. Overlaps often bring more participants and higher trading volume, especially London with New York.
Which pairs are most active in each session?
Pairs involving the currencies of the open centers tend to be more active. AUD and NZD pairs often see interest during Sydney hours, JPY pairs during Tokyo, and EUR, GBP and USD pairs during London and New York.
Why does the overlap time change in March and in late October or November?
The UK and US switch to and from daylight saving time on different dates, so for a few weeks each year the London–New York overlap is an hour longer than usual.
Is it better to trade during overlaps?
Not necessarily. Overlaps often bring tighter spreads and more movement, but more movement also means more risk. What suits you depends on your strategy and schedule.
