This indicator draws a histogram on the left side of the chart. This histogram contains the historical volume, and inside the histogram, the length of the bars shows the cumulative volume. Traders can configure the price series (open, high, low etc.) with the help of the properties dialog box. An up bar (where the close is above the open) shows the bar in green, and falling bars are displayed in red. The indicator is only designed to be used with historical data. In order to view volume changes in real-time, it is wise to consider using the VolumeProfile.
