The total volume traded for a financial instrument is the sum total of all quantities that were traded (bought and sold, but counted once) in the day. For example, if trader A buys 10 quantities of stock X from trader B, while trader C sells 20 quantities of the same stock X to trader D, the total volume traded for X would be 10 + 20 = 30. It won't be 10 + 10 + 20 + 20 = 60 because the contribution of the trade to the total volume is considered only once. This data is dynamic in nature and may increase at any moment during the live trading hours.
