Forex trades around the clock—but liquidity is not constant
The global FX market spans Asia, Europe and North America. Session overlap, local holidays, macro releases and rollover can change spreads and execution even when the market is technically open.
The three-session mental model
JPY, AUD, NZD and regional data can be especially relevant. Liquidity in some European crosses can be thinner than during London.
A major global liquidity centre. EUR, GBP and many cross pairs typically see deeper activity during the European morning.
U.S. and Canadian macro data, Treasury-market moves and the London–New York overlap can produce heavy FX activity.
Why the London–New York overlap matters
Two major financial centres are active at the same time, so many major currency pairs often have deeper liquidity and tighter normal-session spreads. “Often” is not “always”: holidays, news and sudden risk events can still change conditions quickly.
Rollover
Many retail FX providers process overnight financing and daily accounting around a set rollover time. Liquidity can become thinner around this transition, and some providers widen spreads. The exact time and financing calculation are provider-specific.
Daylight saving time
Session relationships can shift temporarily because countries change clocks on different dates. Use UTC or your device's time-zone conversion rather than memorizing one fixed local-time table all year.
Events override normal session expectations
Central-bank decisions, inflation, payrolls and unexpected headlines can produce more volatility than the normal session pattern. Pair session context with the economic calendar rather than using time-of-day as a signal.
Session checklist for traders
- Which financial centres are open?
- Is there a local or major-market holiday?
- Is a high-impact release due within the next hour?
- Is the provider near rollover or maintenance?
- Is the current spread normal for this instrument and account?
- Does the strategy depend on low latency or stable spreads?
