Quick answer · Overlaps
What are forex session overlaps?
Forex session overlaps are the hours when two major sessions trade at once. Liquidity jumps, spreads tighten, and directional moves get cleaner. The three windows are Sydney–Tokyo, Tokyo–London, and the market's peak: London–New York (13:00–17:00 UTC), which carries roughly 50% of daily volume.

| Overlap | UTC | Duration | Volume |
|---|---|---|---|
| London – New York | 13:00 – 17:00 | ~4 hours | Highest (~50%) |
| Sydney – Tokyo | 00:00 – 06:00 | ~6 hours (AEST) / ~5 (AEDT) | Moderate |
| Tokyo – London | 08:00 – 09:00 | ~1 hour | Sharp / short |
Why overlaps matter
13:00 – 17:00 UTC
Best liquidity
- More participants — two financial centres active at once deepen the book.
- Tighter spreads — EUR/USD often falls to 0.1–0.3 pips in London–NY.
- Cleaner trends — institutional flow concentrates into these hours.
Overlap Analysis
What makes each window unique
London – New York
The London–New York overlap is the single most important window in the forex market. Running for approximately 4 hours each trading day (8:00 AM – 12:00 PM ET / 13:00–17:00 UTC), it accounts for roughly 50% of total daily forex volume — more than any individual session produces on its own.
Europe’s largest financial centre and North America’s primary trading hub are both fully operational. Banks in London, Frankfurt, Zurich, and Paris overlap with institutions in New York, Chicago, and Toronto. Order books deepen, spreads tighten (EUR/USD regularly below 0.2 pips), and trends strengthen.
Major US releases — Non-Farm Payrolls, CPI, Fed decisions — typically land at 8:30 AM ET, right at the start of this window. For day traders and scalpers, no other period offers a comparable mix of liquidity and conviction.
Sydney – Tokyo
The Sydney–Tokyo overlap spans approximately ~6 hours in AEST (~5 in AEDT) and is the longest concurrent trading window. It does not match London–New York in absolute volume, but it is the primary session for Asia-Pacific price discovery.
AUD/JPY is the defining pair, with both Australian and Japanese systems fully engaged. AUD/USD, NZD/USD, and NZD/JPY also see meaningful activity. Commodity-currency and carry-trade setups tend to work best here.
Volatility is usually moderate and range-bound versus European hours — a natural fit for mean-reversion. Catalysts include RBA decisions, Japanese GDP, and Chinese data that often drops early in the Asian day.
Tokyo – London
The Tokyo–London overlap is the briefest of the three, lasting roughly 1 hour (about 3:00 AM – 4:00 AM ET / 08:00–09:00 UTC). Despite the short duration, it consistently produces sharp moves — the classic London breakout.
Asian hours often consolidate into a defined range. When London opens, European volume frequently breaks that range with conviction. EUR/JPY is the most active cross; GBP/JPY also moves.
Breakout traders mark the Asian high/low and position for London’s opening flow. The main risk is a fakeout that reverses once the first burst settles — use the window as a filter, not a blind trigger.
Which Overlap for Which Strategy?
Match your approach to the right peak window
Scalping & High-Frequency
London–New York. Maximum liquidity means fast fills, minimal slippage, and spreads tight enough for micro-pip strategies across a full 4-hour window.
Trend Following
London–New York for the strongest intraday trends, or Tokyo–London to catch the London breakout early.
Range & Mean Reversion
Sydney–Tokyo. Lower volatility and more predictable bands suit AUD/JPY and AUD/NZD before European volume disrupts the range.
Breakout & News
Tokyo–London for the London breakout, or London–New York around US data. Position before the catalyst; manage risk tightly.
Key insight: Volume alone does not guarantee profitability. London–New York suits trend-following; Sydney–Tokyo suits range work. Match strategy to the overlap.
Frequently Asked Questions
What are forex session overlaps?
Forex session overlaps are periods when two major trading sessions are open simultaneously. Because traders from two financial centres are active at once, these windows see increased volume, tighter spreads, and more directional price action. The three primary overlaps are London–New York, Sydney–Tokyo, and Tokyo–London.
Which forex overlap has the highest volume?
The London–New York overlap. This ~4-hour window accounts for roughly 50% of daily forex turnover, with peak liquidity across EUR/USD, GBP/USD, and other majors.
What time is the London-New York overlap?
Approximately 8:00 AM to 12:00 PM Eastern Time (13:00 to 17:00 UTC). Times can shift slightly during daylight saving transitions. Use the live cards at the top of this page for your local window.
What pairs are best during overlaps?
London–New York: EUR/USD, GBP/USD, USD/CHF. Sydney–Tokyo: AUD/JPY, AUD/USD, NZD/JPY. Tokyo–London: EUR/JPY, GBP/JPY. Trade pairs that involve currencies from both active sessions.
Is the Tokyo-London overlap worth trading?
Yes, with caveats. At ~1 hour it demands quick decisions and can produce sharp London breakouts against the Asian range. Fakeouts are common — tight stops and a clear plan help.
How do overlaps affect spreads?
More liquidity providers mean tighter spreads. During London–New York, EUR/USD can drop to 0.1–0.3 pips. Between New York close and Sydney open, spreads can widen 3–5x.
