On Balance Volume (OBV)

 Print this Topic Previous pageReturn to chapter overviewNext page

Description

OBV is a simple indicator that adds a period's volume when the close is up and subtracts the period's volume when the close is down. A cumulative total of the volume additions and subtractions forms the OBV line. This line can then be compared with the price chart of the underlying security to look for divergences or confirmation.
