Notional volume is a distinct measurement of trading volume in a specific time frame that is frequently compared to market value, which is the current price of a security that can be purchased or sold through a brokerage or exchange service. As an example, suppose a call option representing 100 shares of a particular stock with a strike price of $50 trades on the market for $3.0 per contract (100 x $3.0 = $300 market value), but its notional value is $3,000 (100 x $50). This is an example of notional volume classification.
