Forex Market Hours and Trading Sessions

When the forex market opens and closes

Forex has no central exchange, just a network of banks and brokers, open wherever a major financial centre is awake.

• Opens around 21:00–22:00 UTC on Sunday, as Sydney starts its Monday morning.
• Closes around 21:00–22:00 UTC on Friday, as New York finishes.

In between it does not close, though most servers take a short maintenance break around 21:00 UTC at the daily rollover. All times here are UTC.

The four trading sessions in UTC

The day splits into four sessions, named after the centres driving them.

Standard-time figures: Europe and North America move their clocks part of the year, shifting the London and New York rows by an hour.

Session overlaps and what changes across the day

Sessions overlap, and the overlaps are where the most money changes hands.

• Tokyo and London, 08:00–09:00 UTC. One narrow hour.
• London and New York, 13:00–17:00 UTC. Four hours, and by a wide margin the busiest part of the day, with both of the largest centres open at once.
• New York close into Sydney, 21:00–00:00 UTC. The thinnest stretch of the week.

This shows up in the spread: when many participants are quoting, the gap between bid and ask is typically narrowest; when few are, it widens. If bid and ask are new terms, how to read a forex quote covers them.

Which hours suit you depends on your own timetable and method. No session is the right one to trade.

How the sessions land in the Gulf, Africa and South Asia

Most of the Gulf, Africa and South Asia do not change their clocks. Europe and North America do, so the local time of the London and New York opens moves by an hour in late March and late October while yours stays put. Standard-time local starts:

From West Africa, London sits inside the working day. From the Gulf and East Africa, the London–New York overlap runs through the afternoon and evening. From South Asia, it begins in the evening and runs past midnight.

Hours are set instrument by instrument: the contract specifications for each forex CFD give the exact open, close and daily break for that pair.

Rollover, swap and the weekend gap

Rollover. Positions held through the daily rollover, around 21:00 UTC, are charged or credited a swap: the financing cost of holding overnight. One day a week, commonly Wednesday, three days of swap are applied at once to cover the weekend.

The weekend gap. The market stops on Friday and restarts on Sunday, but events do not. The first Sunday price can sit far from Friday’s close, and any pending order or stop-loss in that gap fills at the first available price, not at your level. That is one reason order types matter before you leave a position open across the break.

Worked example: the same order at two times of day

Take GBP/USD at 0.10 lots, where one pip is worth about $1. The order is identical in both cases; only the clock changes.

13:30 UTC, inside the London–New York overlap. A typical spread might be around 1 pip, so opening the position costs about $1 and it shows roughly -$1 the moment it fills.

23:00 UTC, after New York has closed. The same pair might be quoted 3 to 4 pips wide, so the identical order costs about $3 to $4.

Same instrument, same size, same direction, three to four times the entry cost, before price has moved at all.

A second effect: a long is closed on the bid, so if your stop-loss sits 20 pips below entry and the spread widens from 1 pip to 4, the market has 3 pips less to travel before that stop is touched. Wide spreads do not only cost more to enter. They move your exit closer.

Key takeaways

• The forex week runs from around 21:00–22:00 UTC on Sunday, when Sydney opens, to the same hour on Friday, when New York closes.
• The London–New York overlap, 13:00–17:00 UTC, is the busiest stretch of the day; the hours after the New York close are the thinnest.
• Spreads typically widen in quiet hours, raising entry costs and bringing a stop-loss closer to being touched.
• Because most of the Gulf, Africa and South Asia do not change their clocks, the local time of the London and New York opens shifts twice a year.

Common questions about forex market hours

Is the forex market really open 24 hours a day?

For five days a week, yes. From the Sydney open on Monday to the New York close on Friday, one major centre is always trading. Most servers pause briefly at the daily rollover around 21:00 UTC, and some instruments have their own short breaks.

What time does the forex market open on Monday?

Around 21:00–22:00 UTC on Sunday, which is Monday morning in Sydney. In local terms that is roughly 01:00–02:00 in Dubai, 00:00–01:00 in Nairobi and Riyadh, and 02:30–03:30 in Delhi and Colombo. The exact minute varies by broker and by time of year.

Why is the spread wider at night?

Fewer participants are quoting. The spread reflects how many banks and other players will buy and sell at that moment. When London and New York are both closed that number falls and the bid-ask gap widens, narrowing again as London comes in.
