The foreign exchange market has no single exchange and no closing bell. It trades around the clock from Monday morning in Asia to Friday evening in New York. But "always open" does not mean "always the same". Activity rises and falls as the world's financial centres open and close, and that rhythm matters for every trade you take.
The four main sessions
Traders usually describe the day as four overlapping sessions, named after the centre that dominates each one. Business hours are roughly 8:00 to 17:00 local time in each city:
| Session | Local hours | UTC in northern winter | UTC in northern summer |
|---|---|---|---|
| Sydney | 08:00 to 17:00 | about 21:00 to 06:00 | about 22:00 to 07:00 |
| Tokyo | 09:00 to 18:00 | 00:00 to 09:00 | 00:00 to 09:00 |
| 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 |
These are conventions, not official opening times, and different brokers draw the edges slightly differently. Japan does not use daylight saving time; the others do, on different dates. In late October and in March, the UK and the US change their clocks a week or more apart, so for a short time the gap between London and New York is one hour shorter than usual.
What each session is like
Sydney and Tokyo
The Asian sessions are usually the quietest for the major pairs. Ranges tend to be narrower. The Japanese yen and the Australian and New Zealand dollars are most active here, and so is news from China and Japan.
London
London is the largest centre for currency trading, and its open often brings the first strong move of the day. The euro, the pound and the Swiss franc are especially active, and many breakouts from the overnight range happen in the first hours of this session.
New York
The New York session brings US economic data, such as employment and inflation releases, which can move every dollar pair and gold within seconds. It is also when US stock indices trade.
The overlap that matters most
When London and New York are both open, roughly the four or five hours from New York's morning until London's close, the market is usually at its deepest. Spreads tend to be tight and moves tend to be larger. For gold in particular this window often carries the day's main move, because both of the biggest centres for the metal are trading at once.
What this means for your trading
- Know which session you trade in. A breakout strategy that works at the London open may fail in the quiet hours of Asia.
- Watch the news calendar. Major releases come at fixed times, often at the start of the New York session. Spreads can widen around them.
- Expect thin markets at the edges. Late Friday, Sunday's reopening and public holidays can bring wide spreads and sudden gaps.
- Mind the weekend. The market is shut from Friday evening to Sunday evening (UTC). Prices can open on Monday some distance from where they closed, jumping straight past a stop.
- Fit sessions to your life. A trader who can only watch the market in the evening should choose pairs and setups that suit that window, not fight it.
Sessions and signals
Signals for gold, forex and indices are worth more when they arrive while their market is actually trading, so check which session you are in before you act on a call. You can follow our live signals for forex, gold and crypto, and the risk-to-reward ratio of each one is shown with it.
In short
Forex trades 24 hours a day on weekdays, but its energy comes in waves: quiet in Asia, decisive at the London open, and busiest while London and New York overlap. Knowing which wave you are in explains much of what the chart is doing, and helps you choose when to trade and when to wait.
