The forex market never has a single opening bell. Trading follows the sun from one financial centre to the next, from Sunday 17:00 to Friday 17:00 New York time. Traders usually split the day into four sessions.
The four sessions (local time in each centre)
| Session | Local hours | Character |
|---|---|---|
| Sydney | 07:00 – 16:00 | Quiet, opens the week, AUD and NZD active |
| Tokyo | 09:00 – 18:00 | JPY, AUD and NZD pairs; often range-bound |
| London | 08:00 – 17:00 | The busiest single centre; trends often start here |
| New York | 08:00 – 17:00 | US data releases; USD and CAD pairs very active |
Because daylight saving changes on different dates in each country, these times shift against each other through the year. Our market hours tool converts them into your own time zone automatically, for example London, Dubai, Lagos or Singapore.
The overlaps
- London + New York (around 12:00–16:00 UTC, depending on daylight saving) is the most liquid window of the day. Spreads are tight and big moves are common, especially around US data releases at 08:30 New York time.
- Tokyo + London is a shorter overlap in the European morning that often sets the tone for the European session.
- Sydney + Tokyo is the Asian morning. It is relatively calm except around Australian, New Zealand or Japanese data.
Which pairs move in which session
The data on our market pages shows it clearly. For example, compare the London and New York average ranges with the Asian range on EUR/USD and GBP/USD: the European and US sessions typically produce about twice the movement of the Asian session. Yen pairs such as USD/JPY and AUD/JPY see relatively more of their daily range during Tokyo hours.
As a rule of thumb:
- Asian session: JPY, AUD, NZD pairs
- London session: EUR, GBP, CHF pairs and crosses
- New York session: USD and CAD pairs, plus anything around US data
Why sessions matter for your trading
- Volatility affects stop placement. A 15-pip stop that survives the Asian session might be taken out in seconds at the London open.
- Breakouts need participation. Range breaks during quiet hours fail more often.
- Spreads widen when liquidity thins. This happens in the hour around the daily rollover (17:00 New York) and on Friday evenings.
- Weekend gaps. The market closes Friday and reopens Sunday. Price can open far from Friday’s close if news breaks over the weekend.
Plan your trading around the sessions that fit your life and the pairs you follow, not the other way round.
