VolumeBar™
Volume bars plot bars based on a specified trade volume. For example, you can plot bars every time 100, 200, 1,000, etc. shares are sold. A new volume bar is built every x-number of shares sold (where x is the volume you specify).

Volume bars record the Open, High, Low, and Closing prices for a specified volume of shares traded. Volume-based bar charts are helpful for traders interested in analyzing trading volume.
Note: The volume entered in the Volume Bar box is multiplied by a factor of 100. For example, to build bars based on 100 trades, enter 1 in the Volume Bar box. The minimum number of shares traded to create a volume bar is 100.
