<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: small;"><span style="line-height: 115%;">According to the basic theory of
volume as developed by Charles Dow, volume should rise in the direction of the
<a href="http://prkschool.blogspot.in/2012/12/6-trend-lines.html" target="_blank">trend</a> which basically implies that during an uptrend, volume must rise together
along with the rising price and in a <a href="http://prkschool.blogspot.in/2012/12/6-trend-lines.html" target="_blank">downtrend</a> the <a href="http://prkschool.blogspot.in/2012/12/31-price-volume-trend.html" target="_blank">volume</a> must rise when the
price goes down. This rising volume confirms the quality of the trend. With the
passage of time, as more and more research came into the subject, the theory of
On Balance Volume (OBV) was developed.</span></span></span></div>

<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: small;"><span style="line-height: 115%;">According to this theory, volume is correlated with the change in price.
On Balance Volume (OBV) actually measures buying and selling pressure on a
cumulative basis which subtracts volume on down days and add volume on up days.</span></span></span></div>

Joe Granville and it is one of the first indicators to measure positive and
negative volume flow. People often use OBV to confirm price trend and also look
for divergence between price and OBV.</span></span></span></div>

yesterday’s <a href="http://prkschool.blogspot.in/2012/12/6-trend-lines.html" target="_blank">volume</a> should be added to today’s volume and the total volume
should be called On Balance Volume (OBV) for today. If today’s closing price is
lower than yesterday’s, then yesterday’s <a href="http://prkschool.blogspot.in/2012/12/6-trend-lines.html" target="_blank">volume</a> should be subtracted from

<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: small;"><span style="line-height: 115%;">We are not concerned with the
absolute figure of daily On Balance Volume, rather what we are concerned about
is overall direction of the OBV line. The OBV line is simply a running total of
positive and negative v<a href="http://prkschool.blogspot.in/2012/12/19-volume.html" target="_blank">olume</a>.</span></span></span></div>

<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: small;"><span style="line-height: 115%;">During an uptrend On Balance Volume will follow the price direction and
will keep on making higher top and higher bottom. Hence both charts i.e. price
chart and OBV chart will almost look identical. As long as both charts move in
the same fashion, trend is said to be perfectly up i.e. volume is supporting
the rise in price.</span></span></span></div>

<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: small;"><span style="line-height: 115%;">On the other hand, during a
downtrend, OBV should make lower top and lower bottom in the same style as
price and it confirms that volume is supporting the downtrend and it is
perfectly intact.</span></span></span></div>

<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: small;">During a downtrend, price

lower bottom. At times we will find that volume and price both are not moving
in tandem i.e. price has broken the last bottom but volume could not break. It
shows that price has broken with the lesser volume. This is the point of
trouble for the downtrend because volume is no more supporting the price fall.
This is called non-confirmation. This type of confirmation occurs at the end of
bear market.</span></span></div>

<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-size: small;">Another important and
interesting factor of On Balance Volume is advanced breakout. As price and
volume keeps on rising together, there seems to be no problem but a time will
come where we will see that price could not breach the previous top, but OBV
line has breached the previous top. This is called advanced breakout. It shows
that although price has gone up marginally but volume generation is so high
that OBV has made an advanced breakout. This is the signal which tells us that
price will also cross the previous top. In fact a non-confirmation is a matter
of weakness whereas advanced breakout is a matter of strength.</span></span></div>

similarities. Moreover, OBV should always be used in the daily chart in

make better trades, you may combine it other indicators like Stochastic for
better confirmation. Let’s take an example to understand it better. You may
confirm the advanced breakout with that of positive divergence of Stochastic,
to place your trade for the upside. On the other hand, you may combine negative
divergence with the non-confirmation, to bet on the downside price movement.</span></span></span></div>
