The market is open 24/5 — but not evenly
Forex trades around the clock from Sydney's Monday open to New York's Friday close, but that continuous tape is stitched from four regional sessions that hand off to each other. Volume is wildly uneven across them. The right question is never "is the market open?" — it almost always is — but "is there enough activity right now for my pairs to move cleanly and cheaply?"
The four sessions, in UTC
Times are approximate and shift by an hour with daylight saving in London and New York, so anchor on UTC and let the live clock do the conversion:
| Session | Approx. hours (UTC) | Character |
|---|---|---|
| Sydney | 22:00 – 07:00 | Thin open; sets the Asian tone |
| Tokyo (Asian) | 00:00 – 09:00 | JPY & AUD/NZD activity, ranges |
| London | 08:00 – 17:00 | Deepest liquidity; trends begin |
| New York | 13:00 – 22:00 | US data, second wave of volume |
The window that actually matters: London–New York overlap
From roughly 13:00 to 17:00 UTC, London and New York are both open. This four-hour overlap is the busiest stretch of the entire trading day: two of the world's largest financial centres are active at once, the major US economic releases land, and liquidity is at its deepest.
Why deep liquidity is the goal and not just a statistic:
- Tighter spreads. More participants means the gap between bid and ask narrows, so your cost to enter and exit falls.
- Cleaner moves. Real volume produces follow-through instead of the choppy, stop-hunting drift of a thin market.
- Levels behave. Support, resistance, and breakouts are more trustworthy when there is genuine participation behind them.
If you trade the majors — EUR/USD, GBP/USD, USD/JPY — and you can only watch the screen for part of the day, the London open through the London–New York overlap (≈08:00–17:00 UTC) is where your effort is best spent. It's the highest-quality liquidity of the day.
Match the pair to the session
A currency is most active when its home market is awake. Trading a pair in its dead session is how you end up in a flat, spread-eroded range:
- EUR/USD, GBP/USD, EUR/GBP — London and the overlap.
- USD/JPY, AUD/USD, NZD/USD, AUD/JPY — the Tokyo/Asian session, plus the overlap for the USD leg.
- USD/CAD — the New York session, alongside US and Canadian data.
The rollover trap
Around 21:00–22:00 UTC (5pm New York time) the trading day rolls over. For an hour or so, liquidity drains to its thinnest of the day: spreads widen sharply, fills get unreliable, and a single order can jolt price. It's also when brokers apply the daily swap (overnight financing) to open positions. Spikes printed in this window are usually liquidity artefacts, not signals. Standing aside through the rollover is almost always the right call.
More screen time is not more edge. The dead hours of the late US afternoon and the pre-London Asian lull are where overtrading lives — thin markets, wide spreads, false moves. Picking your window and ignoring the rest is a discipline, not a limitation.
