On Balance Volume (OBV) was developed by Joe Granville.  It was introduced in his 1963 book, Granville's New Key to Stock Market Profits.  It operation measures buying and selling pressure as a cumulative indicator.  On price up-bars, it adds volume of the the price bar.  On price down-bars, it subtracts the bar's volume from the accumulated series.

 

This indicator's purpose was to measure positive and negative price volume flows.  It is often applied with a divergence calculation that measure agreement between OBV and price.  When the price and OBV directions agree, OBV is viewed as a supporting indicator of the current near term price movements.
