Different markets are open at different times: shares trade during their exchange's defined hours, forex runs continuously through the weekday across regional sessions, futures trade nearly around the clock on weekdays with short daily breaks, and crypto trades every hour of every day. When a market is open, and when within those hours it is most liquid, shapes how and when you should trade it.

Target audience: Traders deciding what to trade around a fixed schedule, who need to know when each market is live and liquid.

Learning objectives

  • ✓Describe the trading hours of the main instrument classes.
  • ✓Identify when within the hours liquidity is highest.
  • ✓Recognise gap risk around closes and weekends.
  • ✓Match your trading time to your instrument's liquid hours.

Definition

Different markets are open at different times: shares trade during their exchange's defined hours, forex runs continuously through the weekday across regional sessions, futures trade nearly around the clock on weekdays with short daily breaks, and crypto trades every hour of every day. When a market is open, and when within those hours it is most liquid, shapes how and when you should trade it.

Why it matters

The hours an instrument trades determine when you can act, when liquidity and volatility are highest, and when gaps and thin conditions are likely, so they directly affect both opportunity and risk. Matching your trading to when your instrument is genuinely liquid, and respecting the quiet and closed periods, avoids a large class of avoidable problems from thin-hour fills to weekend gaps.

When each market is open

The classes differ sharply in their hours. Shares trade during their exchange's session, a defined window on weekdays, with limited activity before and after in many markets. Forex runs continuously from the start of the trading week to its end, flowing around the globe through the regional sessions as different financial centres open and close. Futures trade nearly around the clock on weekdays, with a short daily maintenance break and a distinction between the main session and the quieter extended hours. Crypto is the outlier, trading every hour of every day with no close at all. Knowing your instrument's calendar is the starting point.

Open is not the same as liquid

Being open does not mean being equally tradable throughout. Even a continuously-open market like forex has clear peaks and troughs in activity: liquidity and volatility concentrate when major financial centres are active and overlap, and thin out in the gaps between them. Futures are far more liquid in their main session than in extended hours. The practical point is that the best conditions, tightest spreads and steadiest behaviour, cluster in specific windows, and trading in the dead, low-liquidity stretches means wider spreads, more slippage, and less reliable structure, even though the market is technically open.

Gaps and the risks of closes

Markets that close create gap risk: news and events occur while the market is shut, and price can reopen at a very different level than it closed, jumping straight past any stop in between. This is most visible in shares and futures over weekends and holidays, where a position held through the closure is exposed to whatever happens while you cannot act. Crypto, trading continuously, has no weekend gap of this kind but can still move violently in low-liquidity hours. Understanding when your instrument is closed, and what holding through that closure exposes you to, is part of trading it responsibly.

Worked examples

Example 1: The gap over the weekend

A trader holds a position in a market that closes for the weekend, with a stop set at what looks like a safe level. Over the weekend a major event occurs while the market is shut, and on the reopen price gaps straight through the stop, filling far beyond it, so the realised loss is much larger than the stop implied. A trader aware of the gap risk would have reduced size or closed before the weekend, or accepted the exposure deliberately. The stop did not fail; the market simply jumped past it while closed, which is the nature of holding through a closure.

Common mistakes

Trading in an instrument's dead, low-liquidity hours by habit.

Assuming an open market is equally liquid throughout its hours.

Holding through a weekend or closure without accounting for gap risk.

Relying on a stop to limit loss across a market closure.

Ignoring the session overlaps where liquidity and volatility peak.

Myth vs reality

Myth

That open means equally tradable at any hour.

Reality

No paired reality note provided.

Myth

That a stop protects you across a market closure.

Reality

No paired reality note provided.

Myth

That a continuously-open market like crypto has no thin, risky hours.

Reality

No paired reality note provided.

Risk considerations

  • Price can gap past a stop across a closure, realising a larger loss.
  • Thin-hour conditions bring wider spreads, more slippage, and less reliable structure.

Practice exercises

1. Chart your instrument's day and week

Map when your instrument is open, when it is most liquid, and when it is closed.

  1. Write your instrument's trading hours and any daily break.
  2. Mark the windows when it is most liquid (session overlaps, main session).
  3. Mark when it closes and where gap risk arises (weekends, holidays).
  4. Match your available trading time to its genuinely liquid hours.
