Answer Capsule: The forex market opens Sunday 22:00 GMT (Sydney) and closes Friday 22:00 GMT (NY). The London-NY overlap (13:00-17:00 GMT) accounts for 70% of daily forex volume and offers the best trading conditions.

The forex market operates 24 hours a day, 5.5 days a week, across four major trading centers. When one session closes, another opens — creating a continuous cycle of liquidity from Sunday 22:00 GMT to Friday 22:00 GMT. Each session has distinct characteristics: Sydney opens the week with moderate liquidity, Tokyo brings Asian pair volume, London is the heavyweight (34% of all forex volume), and New York drives the afternoon overlap.
The key insight: session transitions and overlaps create the highest liquidity windows. Spreads tighten, slippage decreases, and institutional order flow peaks. The London-NY overlap alone accounts for approximately 70% of daily forex trading volume. Smart traders time their entries to these windows — not because they can predict price, but because execution quality is dramatically better.

The London-New York overlap (13:00-17:00 GMT) is the #1 trading window. EURUSD, GBPUSD, and XAUUSD see their tightest spreads and highest volume during this 4-hour window. The Tokyo-London overlap (08:00-09:00 GMT) is shorter but drives significant moves in GBPJPY and EURJPY.
Session overlaps matter because they bring twice the market participants. More participants = more liquidity = tighter spreads = better fills. For scalpers and day traders, trading outside overlap windows means accepting wider spreads and higher slippage. For swing traders, session timing matters less — but entry execution still benefits from overlap liquidity.
| Sydney | 22:00 — 07:00 GMT |
| Tokyo / Asian | 00:00 — 09:00 GMT |
| London / European | 08:00 — 17:00 GMT |
| New York / US | 13:00 — 22:00 GMT |
London-New York overlap (13:00-17:00 GMT) is the most traded window, with the highest liquidity and tightest spreads on EURUSD, GBPUSD, XAUUSD.
| Session | Best Pairs | Reason |
|---|---|---|
| Sydney (22:00-07:00) | AUDUSD, NZDUSD, AUDJPY | Australian/New Zealand economic data released; local banks active |
| Tokyo (00:00-09:00) | USDJPY, EURJPY, GBPJPY, AUDJPY | Japanese banks and institutions dominate; yen crosses most active |
| London (08:00-17:00) | EURUSD, GBPUSD, EURGBP, FTSE, DAX | 34% of global forex volume; European data releases drive moves |
| New York (13:00-22:00) | EURUSD, USDJPY, GBPUSD, XAUUSD, US indices | US economic data; institutional order flow peaks at NY open |
| London-NY Overlap (13:00-17:00) | EURUSD, GBPUSD, XAUUSD, SP500, NAS100 | Highest liquidity of the week; tightest spreads; best execution |
Two traders can take the same setup with completely different results — simply because of when they entered. A EURUSD breakout during the Asian session (thin liquidity) may stall or reverse. The same breakout during London-NY overlap (deep liquidity) runs cleanly to target. The chart pattern is identical. The liquidity environment is not.
