What's the best hour to trade?

There's no single best hour, only hours that suit your asset and style. Forex is usually most active during the European-US overlap.

If crypto runs all week, does it have sessions?

Technically it never closes, but liquidity and volatility still shift with the active hours of major markets.

Why are spreads wider at night?

Because fewer people trade, so liquidity is thin, and brokers widen spreads to offset risk.

Market Sessions | 2AiTrading

What trading sessions are

A trading session is the part of the day when a market is open for buying and selling. Each asset class has its own schedule: Vietnamese stocks run fixed business hours; forex runs nearly 24 hours as the Asian, European, and US financial centers hand off to each other; crypto runs all week.

Why it matters

Liquidity and volatility change by session. For the same currency pair, volatility is high when the European and US sessions overlap and quiet during the Asian session late at night — entering at the wrong hour can mean wide bid-ask spreads and listless price action. Many big moves happen at the open or close of a session, or when major sessions overlap; knowing the schedule lets you act deliberately instead of being caught off guard.

The main sessions

Asian session: Tokyo, Singapore, Hong Kong — usually calmer for major pairs, livelier for Asian assets.
European session: London is the hub, with the deepest forex liquidity.
US session: New York, where much important economic news is released.
Overlap window: when the European and US sessions are both open — evening in Vietnam — is typically when forex is most volatile and liquid.
Vietnamese stocks: fixed hours on business days, with morning and afternoon sessions plus periodic matching auctions at the open and close.

How to apply it

Pick trading hours that suit your asset and your style. Intraday forex traders often favor the European-US overlap. Avoid entering during thin liquidity — when spreads are wide and slippage is likely — without a clear reason. Note that major news tends to come out on the schedule of its corresponding session.

A concrete example

A Vietnamese trader trading EUR/USD at 9 a.m. in the Asian session sees the price drifting sideways with a slightly wide spread. The same pair at 8 p.m., when Europe and the US overlap, is clearly more volatile and the spread tightens. This isn't "the evening strategy is better" — it's the same market with a different rhythm by session.

Common mistakes

Trading regardless of the clock, ignoring session liquidity.
Holding forex overnight while forgetting the overnight fee, which triggers at the session's day-rollover point.
Being surprised by volatility at the session open or overlap because you didn't know the schedule.
Applying one market's hours to another, when Vietnamese stocks, forex, and 24/7 crypto are three entirely different schedules.
