Trading Volume

The total amount of an asset traded within a specific time period, typically measured in USD or the base currency.

What is Trading Volume?

Trading volume measures the total quantity of an asset bought and sold during a specific period. It's one of the most important indicators of market activity and liquidity.

Types of Volume

Spot Volume

Actual buying and selling of the underlying asset.

Derivatives Volume

Trading of futures, perpetuals, and options contracts. Often much larger than spot volume.

24h Volume

The standard measurement period, showing total trades in the last 24 hours.

Why Volume Matters

  1. Liquidity: High volume = easier to buy/sell without moving price
  2. Trend Confirmation: Price moves with high volume are more significant
  3. Breakout Validation: Breakouts on high volume are more reliable
  4. Market Interest: Rising volume shows increasing attention
