<div>'''On-balance volume''' ('''OBV''') is a [[technical analysis]] indicator intended to relate price and volume in the [[stock market]]. OBV is based on a cumulative total volume.<ref name="Granville" /><br />
<br />
==The formula==<br />
<br />
: <math><br />
OBV = OBV_{prev} + \left\{ \begin{matrix}<br />
volume & \mathrm{if}\ close > close_{prev} \\<br />
0 & \mathrm{if}\ close = close_{prev} \\<br />
-volume & \mathrm{if}\ close < close_{prev}<br />
\end{matrix} \right.<br />
</math><br />
<br />
==Application==<br />
Total [[volume (finance)|volume]] for each day is assigned a positive or negative value depending on prices being higher or lower that day. A higher close results in the volume for that day to get a positive value, while a lower close results in negative value.<ref> [http://www.oxfordfutures.com/futures-education/tech/on-balance-volume.htm ''On Balance Volume ( OBV )'']. 22 September 2007.</ref> So, when prices are going up, OBV should be going up too, and when prices make a new rally high, then OBV should too. If OBV fails to go past its previous rally high, then this is a negative [[divergence]], suggesting a weak move.<ref> [http://financial-edu.com/on-balance-volume-obv.php OBV Behaviorial Limitations and Formulas] at Financial-edu.com.</ref><br />
<br />
The technique, originally called "cumulative volume" by Woods and Vignolia, was later named in 1946, "on-balance volume" by [[Joseph Granville]] who popularized the technique in his 1963 book ''Granville's New Key to Stock Market Profits''<ref name="Granville">Joseph E. Granville, ''Granville's New Strategy of Daily Stock Market Timing for Maximum Profit'', [[Prentice Hall|Prentice-Hall, Inc.]], 1976. ISBN 0-13-363432-9 </ref>. The index can be applied to stocks individually based upon their daily up or down close, or to the market as a whole, using breadth of market data, i.e. the advance/decline ratio.<ref name="Granville" /><br />
<br />
OBV is generally used to confirm price moves.<ref> [http://www.investopedia.com/terms/o/onbalancevolume.asp What Does On-Balance Volume Mean]</ref> The idea is that volume is higher on days where the price move is in the dominant direction, for example in a strong uptrend more volume on up days than down days.<ref> [http://stockcharts.com/education/IndicatorAnalysis/indic-OBV.htm StockCharts.com article on On Balance Volume]</ref><br />
