Stock markets have bells. Forex has sessions. Spot crypto has neither. Coins change hands around the clock, on every day of the year, with no scheduled open, close, lunch break, or holiday. That is why this site does not publish venue hours for crypto.
Why there is no closing time
A stock exchange is a single venue run by a single operator, and that operator decides when the venue opens and shuts. Spot crypto trades across many independent platforms around the world, and each platform runs its own matching system without a daily pause. The assets themselves live on networks that never close. Any single platform can go down for maintenance, but the market as a whole does not.
Then why does volume have a rhythm
Continuous trading does not mean even trading. The people placing orders live in time zones, and they are more active during their own working day and evening. When Asia, Europe, and North America each take their turn, activity rises and falls in waves across the 24 hours.
Looking at historical data, volume has tended to be elevated when European and US business hours overlap. That window lines up with the London-New York overlap used in forex. It is also when many macroeconomic data releases, US stock market hours, and large institutional desks are all active at once. The pattern is a tendency seen in past data, so treat it as context about when more participants tend to be around rather than a signal of what will happen next.
Weekends and thinner hours
Crypto never closes on a weekend, but activity is typically lighter, because many professional participants step away. Overnight hours in the main regions tend to be quieter for the same reason. Lower participation usually means lower liquidity, which can show up as wider spreads and larger price moves on smaller orders. Again, this describes how the market is built, not where prices will go.
Daily candles are a convention
Charts show daily candles with an open and a close, which can look like a market schedule. They are not. A data provider has to cut a continuous stream into days, and most pick a boundary such as midnight UTC. Two providers can legitimately show different daily opens and closes for the same coin. If you compare numbers across tools, check which time boundary each one uses.
How to use the sessions on this site
You can read the London-New York overlap as a timing reference for when participants from both regions tend to be active. The London-New York session page shows whether the overlap is live and converts it to your timezone. Because Europe and the US change their clocks on different dates, the overlap shifts by an hour for a few weeks each year, which the clock gap guide explains.
