The forex week runs 24 hours a day, Monday to Friday. But liquidity and volatility aren't constant — they spike during session overlaps and fade during the quiet hours. Knowing when to trade is as important as knowing what to trade.
The Four Sessions (UTC, approximate)
| Session | Open (UTC) | Close (UTC) | Character |
|---|---|---|---|
| Sydney | 21:00 | 06:00 | Quiet, low vol |
| Tokyo | 00:00 | 09:00 | JPY pairs active |
| London | 07:00 | 16:00 | Highest volume, major moves |
| New York | 12:00 | 21:00 | USD pairs active, news-heavy |
The Golden Overlaps
The best trading happens when two sessions overlap — two financial centers trading simultaneously means double the participants and much higher volatility.
| Overlap | Time (UTC) | Best for |
|---|---|---|
| Tokyo–London | 07:00–09:00 | JPY & GBP volatility |
| London–New York | 12:00–16:00 | EUR/USD, GBP/USD — peak liquidity |
Trade the London–NY overlap
12:00–16:00 UTC is when the most money is moving. This is when EUR/USD, GBP/USD, and USD/JPY have the tightest spreads and cleanest moves. If you can only trade a few hours a day, this is the window.
When NOT to Trade
- ▸Friday afternoon (NY close) — liquidity dries up, weekend gaps can gap your stops.
- ▸Sunday open — spreads are huge, first hour is erratic.
- ▸Major news minutes (NFP, CPI, FOMC) — unless you have a specific news strategy.
- ▸Holiday sessions — skeleton liquidity, unpredictable spikes.
