Trade volume is another name for trading volume, the entry that explains how volume is measured, how traders read it and why it matters. This page explains the variant wording, which appears on many crypto data sites and exchange dashboards.
Trade volume is the total quantity of an asset that changes hands during a period, such as a day, expressed either as a number of units, such as shares or coins, or as a value in a currency, such as US dollars. Every trade counts once, since each sale is also a purchase. High volume suggests strong interest and usually better liquidity, while low volume can mean prices move more easily on small orders. Analysts often look at volume alongside price: a price rise on heavy volume is generally seen as more convincing than one on light volume, and indicators such as on-balance volume are built from it.
The two names are used interchangeably. "Trading volume" is the more common form in finance, while "trade volume" is frequent in crypto listings. The term should not be confused with the volume of international trade in goods between countries, which economists track separately. For a figure covering every trade on a venue, see total exchange volume. In crypto, reported volumes can be inflated by wash trading, so figures from different sources may differ considerably.
