Forex market hours: sessions, the overlap, and the hours to avoid
A live session clock in your own timezone, what each session is like, when each pair actually moves, and the four windows that cost traders money for no reason.
The forex market runs from Sunday 21:00 UTC, when Sydney opens, to Friday 21:00 UTC, when New York closes. It never shuts during the week because the four large trading centres cover the globe between them. What it does do is change character completely depending on which of them are awake.

The four sessions
| Session | UTC hours | What it is like |
|---|---|---|
| Sydney | 21:00 – 06:00 | Thinnest of the four. Ranges are narrow, spreads are at their widest, and the weekly open here is where gaps appear. |
| Tokyo | 00:00 – 09:00 | Yen pairs and AUD, NZD come alive. Otherwise quiet and range-bound. Often sets the day’s early low or high on majors. |
| London | 07:00 – 16:00 | The largest by volume. European data lands here, and most of the day’s real movement on EUR and GBP starts in the first two hours. |
| New York | 12:00 – 21:00 | US data, and the dollar’s main session. Momentum fades noticeably after London closes at 16:00. |
These are conventional market hours, not your broker’s trading hours, which differ by instrument and by broker. Check the symbol specification for the exact schedule of what you trade.
The overlap that matters
Between 12:00 and 16:00 UTC, London and New York are both trading. This is the deepest liquidity of the day: the tightest spreads, the largest ranges, and most of the significant moves on the major pairs.
The practical consequence is that a four-hour window contains a disproportionate share of what happens. A strategy that trades all day is spending most of its time in conditions it was probably not designed for, paying a wider spread for the privilege.
When each pair actually moves
| Pair | Most active |
|---|---|
| EUR/USD, GBP/USD | London open, then the London and New York overlap |
| USD/JPY, EUR/JPY | Tokyo, then again on the New York session |
| AUD/USD, NZD/USD | Sydney and Tokyo, plus Australian and Chinese data |
| USD/CAD | New York, and closely tied to oil |
| Gold (XAU/USD) | London open and the New York session |
The hours worth avoiding, and why
- The daily rollover, around 21:00 to 22:00 UTC. Liquidity providers step away, spreads on majors can multiply several times over for a few minutes, and swap is charged. A stop sitting inside that window can be hit by the spread alone, not by any real move. This is a common and entirely avoidable way to lose a trade.
- The Sunday open. Price resumes wherever the weekend’s news left it, which can be well away from Friday’s close. A gap opens past stops, and the fill is on the other side.
- The first seconds of major data. Spreads widen, execution slows, and slippage is at its worst.
- Late Friday. Positions are being closed rather than opened, so moves lack follow-through.
Anyone running an automated system should know exactly which of these windows it trades in. A time filter is the cheapest improvement available to most short-term systems, and many include one that is switched off by default.
Daylight saving, the detail that breaks schedules
The sessions above are in UTC, which does not change. Local clocks do. London moves in late March and late October; New York moves in mid March and early November; Sydney moves in the opposite direction, being in the southern hemisphere. For a few weeks each year the usual gaps between sessions are an hour out.
This matters more than it sounds for automated systems, because most brokers set their server clock to a fixed offset that also shifts. A robot with hard-coded hours will trade an hour early or late twice a year until someone notices. If a system has a GMT offset setting, this is what it is for.
Is there a best time to trade?
There is a best time for a given strategy, which is not the same question.
- Breakout systems want the London open and the overlap, where volume can sustain a move.
- Range and mean reversion systems want the quiet Asian hours, where price is more likely to stay in a band, if the spread allows it.
- Scalping needs the tightest spreads, so the overlap, and needs to avoid the rollover entirely.
- Swing trading barely cares, because entry timing is noise across a multi-day hold.

Frequently asked questions
When is the best time to trade forex?
It depends on the strategy, not on the market. Breakout systems want the London open and the 12:00 to 16:00 UTC overlap where volume can sustain a move; range systems want the quiet Asian hours if the spread allows; scalping needs the overlap and must avoid the rollover; swing trading barely cares.
Why did my spread jump around 21:00 UTC?
That is the daily rollover. Liquidity providers step away for a few minutes, spreads on majors can multiply several times over, and swap is charged. A stop sitting inside that window can be hit by the spread alone rather than by any real move.
Does daylight saving change the session times?
The UTC hours do not change, but local clocks do, and they move on different dates in London, New York and Sydney. Most brokers set their server clock to an offset that shifts too, so an automated system with hard-coded hours will trade an hour early or late twice a year unless its GMT offset setting is corrected.
