# Delta Volume

Delta volume (***Study > All Studies*** from the top menu bar) displays the difference between the Ask and Bid Volume as a candle chart in a separate graph. Positive values indicate buying pressure and negative values indicate selling pressure. The following screen shot shows the available settings for this study:

* **Number of Bars** – Optionally limits the number of bars that are displayed. This is useful if you want to avoid loading a large amount of historical tick data. Check “Show All” to show a delta bar for every loaded candle.
* **RTH Data only** – Check this box to only show bars that occurred during regular trading hours.
* **Recalculate on Close** – Downloads historical data that replaces the live data after each bar close. This will cause loading after each bar closes.
* **Bar Type** – Type of bar to display (ie OHLC, Candle, Line, Bar etc).
* **Up/@Bid Color** – Display the chosen color if the delta is negative but the price candle closes positive
* **Down/@Ask Color** – Display the chosen color if the delta is negative but the price candle closes negative
* **Indicator** – Settings for the latest value indicator in the vertical axis.
