Trading volume (TV) refers to the amount of base currency a trader is trading. It is calculated using the following formula: 

Trading volume (TV) = Number of lots x contract size

Example 1

An order to Buy 3 lots EURUSD.

TV = 3 x 100 000 EUR = 300 000 EUR

Example 2

An order to Sell 3 lots UKOIL.

TV = 3 x 1 000 BBL = 3 000 BBL

 Trading volume is always calculated in the base currency.

Lot and contract size

Lot refers to the standard unit size of a transaction. A standard lot is typically equal to 100 000 units of the base currency (depending on the instrument).

The several lot types available include: 

  • Standard lot: 1 lot = 100 000 units
  • Mini lot: 0.1 lot = 10 000 units
  • Micro lot: 0.01 lot = 1 000 units
  • Nano lot: 0.001 lot = 100 units

Contract size is a fixed value which denotes the amount of base currency in 1 lot. It varies based on the trading instrument.
