Forex Trading Sessions
The forex market is open 24 hours a day, five days a week. It does not have one opening bell. Instead, trading passes around the world from one financial centre to the next. Each of these blocks of time is called a trading session.
Why the Market Never Sleeps
Forex is traded over the counter (OTC). That means there is no single central exchange. Banks, brokers and funds trade directly with each other through electronic networks. When banks in one city close for the day, banks in another city are opening.
Most traders group the day into four main sessions, named after the biggest centre in each region:
- Sydney (Australia and New Zealand)
- Tokyo (Asia: Tokyo, Hong Kong, Singapore)
- London (Europe: London, Frankfurt, Paris, Zurich)
- New York (North America: New York, Chicago, Toronto)
Note: Session times are not official. They are rough business hours. Different brokers and websites may show them an hour earlier or later.
Session Hours in UTC
We use UTC (Coordinated Universal Time) because it never changes for daylight saving. Convert to your own time zone once and you are set.
| Session | Winter hours (UTC) | Summer hours (UTC) | Main currencies |
|---|---|---|---|
| Sydney | 22:00 – 07:00 | 22:00 – 07:00 * | AUD, NZD |
| Tokyo | 00:00 – 09:00 | 00:00 – 09:00 | JPY, AUD, NZD |
| London | 08:00 – 17:00 | 07:00 – 16:00 | EUR, GBP, CHF |
| New York | 13:00 – 22:00 | 12:00 – 21:00 | USD, CAD |
"Winter" and "summer" here refer to the Northern Hemisphere (London and New York).
Daylight saving (DST): The UK and US move their clocks one hour forward in spring, so London and New York open one hour earlier in UTC. They do not switch on the same day: the US changes on the second Sunday of March and the first Sunday of November, the UK on the last Sunday of March and October. For a week or two each year the gap between the two is one hour shorter than usual. Japan has no DST. * Australia has DST in the southern summer (October to April), the opposite of the north, so real Sydney office hours shift by an hour the other way. Most charts simply show Sydney as 22:00 – 07:00 UTC, which is close enough for planning.
The trading week
The trading day is anchored to 5 pm New York time. The week starts on Sunday at 5 pm New York (22:00 UTC in winter, 21:00 UTC in summer), as Sydney comes online. It ends on Friday at 5 pm New York (same UTC times). Check your broker's server time for the exact minute.

Session Overlaps
An overlap is a period when two sessions are open at the same time. More banks are active, so more orders flow through the market. This usually means tighter spreads (lower cost) and bigger moves.
| Overlap | Winter (UTC) | Summer (UTC) | What to expect |
|---|---|---|---|
| Sydney + Tokyo | 00:00 – 07:00 | 00:00 – 07:00 | Moderate activity in AUD, NZD and JPY pairs |
| Tokyo + London | 08:00 – 09:00 | 07:00 – 09:00 | Short, often a jump in activity as Europe arrives |
| London + New York | 13:00 – 17:00 | 12:00 – 16:00 | The busiest window of the day for most pairs |
Example
You live in Nairobi (UTC+3, no DST). It is January.
London + New York overlap: 13:00 – 17:00 UTC Add 3 hours: 16:00 – 20:00 Nairobi time
So the most active part of your day for EUR/USD is from 4 pm to 8 pm local time.
Tip: The London + New York overlap is also when many big US economic reports come out (for example US jobs data at 8:30 am New York time). Moves can be fast. Learn more in Trading the News.
Which Pairs Move When
A currency is usually most active when its home market is open. A pair is busiest when both of its currencies are in their working day.
| Session | Most active pairs | Typical behaviour |
|---|---|---|
| Sydney | AUD/USD, NZD/USD, AUD/NZD | Quiet, wider spreads, especially Monday morning |
| Tokyo | USD/JPY, AUD/JPY, AUD/USD, EUR/JPY | Steady, often ranges; JPY and AUD news can move it |
| London | EUR/USD, GBP/USD, EUR/GBP, USD/CHF, GBP/JPY | Largest share of daily volume; trends often start here |
| New York | EUR/USD, GBP/USD, USD/JPY, USD/CAD | Very active in the morning, slows after London closes |
Note: London is the largest forex centre in the world, handling roughly 38% of global turnover according to the BIS survey. New York is second at about 19%.
Volatility by Session
Volatility means how much price moves in a given time. More volatility gives more opportunity, but also more risk.
The chart below shows a typical pattern on EUR/USD: a narrow range in the Asian session, then a breakout when London opens.
| Time | Volatility | Spreads |
|---|---|---|
| Sydney / early Tokyo | Low | Wider |
| Tokyo | Low to medium | Normal on JPY/AUD pairs |
| London open | High | Tight |
| London + New York overlap | Highest | Tightest |
| Late New York (after 17:00 UTC) | Falling | Widening |
| Daily rollover (~22:00 UTC) | Very low | Often very wide for a few minutes |
Warning: At the daily rollover, when New York closes, spreads can widen several times over for a few minutes. A tight stop loss can be hit just by the spread. Avoid opening trades in this window.
Weekend Gaps
From Friday's close to Sunday's open, the interbank market is shut. News can still happen. When the market reopens, the first price can be far from Friday's last price. This jump is called a gap.
Example
You are long GBP/USD from 1.2700 with a stop loss at 1.2680, and you hold over the weekend.
Friday close: 1.2714 Sunday open: 1.2662 (below your stop) Your stop fills: about 1.2662, not 1.2680 Planned loss: 20 pips Actual loss: 38 pips
A stop loss becomes a market order once it is hit. In a gap there is no price in between, so you get the next available price.
Best Times for Beginners
There is no perfect hour. But some times are easier to learn in than others.
- Trade the London session or the London + New York overlap for major pairs like EUR/USD and GBP/USD. Spreads are lowest.
- If you live in Asia or Australia, the Tokyo session with USD/JPY or AUD/USD fits your day and is calmer.
- Pick one session that fits your life and learn how your pair behaves in it.
- Check an economic calendar before each session. Step aside a few minutes before major news.
- Avoid the daily rollover and the first hour of Monday's Sydney open.
- Avoid holding trades over the weekend until you understand gap risk.
Tip: Holiday periods (Christmas to New Year, US Thanksgiving, Japanese Golden Week) have thin volume. Price can be slow, then jump suddenly. Many experienced traders simply take time off.
