# BuySellVolume

#### Description <a href="#description_12" id="description_12"></a>

This indicator shows us the current buy or sell pressure based on the volume. For this, trades are classified as "buy" or "sell", whereby for the classification, a "buy" is assumed any time the transaction is executed at or above the ask. A transaction at or below the bid is considered a "sell".

**Caution: This is a real-time indicator and will not work with historical data.**

Similar conditions as with the [*BuySellPressure*](/standard-indicators/buysellpressure.md) apply.
