One lesser-known indicator that can potentially be used to confirm trends and identify reversals is “on-balance volume,” or OBV. If you can figure out how to use on-balance volume to your benefit, it can be a valuable tool at your disposal. Let’s get right into the intricacies of the indicator.

OBV explained

On-balance volume is one of the market indicators you can use to make predictions on where to make your next move in the stock market.

If you’re looking for trend confirmation, look for the OBV to follow the overall price trend. It’s an indicator that leverages the idea that changes in volume often foreshadow changes in price. When looking at this indicator for this purpose, focus primarily on the changes of the OBV’s trends, as well as price. If you’re looking for a change in trend rather than a confirmation, you want to see the OBV and price trend in opposite directions. When this occurs, it can signal a reversal.

On-balance volumes are generally plotted on a price chart, but don’t let it fool you — the OBV’s value on the chart, though still important, is not as important as the overall trend it represents. It’s used simply to get an idea of what to expect from a market and so that you might predict whether to expect a bull or a bear in the future. On-balance volume interpretation is in the eye of the beholder. But an effective OBV trading strategy can make a smart trader’s year if used correctly.

Now that we’ve got an idea of how to use this indicator, let’s take a look at an example.

OBV in the charts

Here’s a daily chart on the PowerShares QQQ Trust, Series 1 (QQQ):

If you look at the chart above, the 50-day simple moving average is plotted, and a support uptrend line is drawn. Below the price chart, you’ll notice the OBV indicator. Now, both the OBV and price were trending higher over this period, indicating a confirmation of trend up until the OBV broke below its lower uptrend line.

Once the OBV broke below that support trend line, it was an indication that there was a bearish divergence, and there could be a reversal in trend.

Here’s what happened after the bearish divergence:

Notice how there was a reversal in trend in the OBV, and thereafter, the price broke below its 50-day simple moving average and uptrend line.

The bottom line

Changes in volume often precede changes in price, and the OBV can be used to determine potential changes in price trends, as well as to confirm a trend. Do your homework, perform further research if you need to, and practice looking for these trends and changes, keeping in mind that no indicator works 100 percent of the time. With this knowledge, you will add an effective piece to your toolkit for swing trades.
