Forex runs 24 hours a day, five days a week — but not all hours are equal. The best time to trade is when volume and volatility are highest, because that’s when spreads are tightest and moves are cleanest. That means the London–New York overlap. This guide breaks down the four sessions, the overlaps, and when to trade — and avoid.
The market follows the sun through four major sessions (times in Eastern Time / ET):
| Session | Hours (ET) | Character |
|---|---|---|
| Sydney | 5:00 PM – 2:00 AM | Quiet open |
| Tokyo (Asian) | 7:00 PM – 4:00 AM | Moderate; JPY pairs active |
| London | 3:00 AM – 12:00 PM | High volume; the biggest session |
| New York | 8:00 AM – 5:00 PM | High volume; USD news |

When two sessions run at once, volume surges. Two overlaps matter:
Yes. Day traders and scalpers want the high-volume overlap, when moves are fast and spreads tight. Swing traders care far less about the hour — they hold for days, so entry timing within a session matters little. Match your hours to your style, as covered in our forex trading strategies guide.
The London–New York overlap, roughly 8:00 AM to 12:00 PM ET, when the two biggest sessions run together and volume peaks.
No — forex runs 24 hours a day but only five days a week, from Sunday evening to Friday evening ET. It closes over the weekend.
It’s high-risk. Spreads widen and prices whipsaw around major releases, so many traders avoid the moments right around scheduled news.
Yes — session overlaps shift by an hour when regions change their clocks, so double-check the times seasonally.
