What Is the On-Balance Volume (OBV) Indicator and How to Use It in Trading?

As trade prices indicate market conditions, the volume traded reveals the ‘why’ behind that money flow. While many traders base their trading decisions on price movements, chart patterns, and technical indicators, they frequently fail to consider an essential part of any market movement: volume. Generally, a strong trend supported by increasing volume is a more reliable trend than one developing with weak volume participation. This is where the On-Balance Volume (OBV) Indicator is an excellent tool. Unlike standard measures of trade activity, OBV provides insights into whether institutions are putting money in or out of an asset through increased volume.

This article will serve as a reference guide to understand how the OBV indicator works, as well as how to read its signals and use OBV-based trading strategies. It also provides traders with advantages, disadvantages, and how to combine OBV with professional market analysis tools to assist in making informed trading decisions.

What Is the On-Balance Volume (OBV) Indicator?

Volume is frequently a predictor of change in price. When the volume of a security is increasing without any movement in the security price, it typically indicates that «smart money» is buying or selling to accumulate shares of a particular security before significant price movement occurs.

By tracking the movement of the on-balance volume line, traders can gain insight into the strength of the trend and help identify potential trend reversals. The on-balance volume line creates a cumulative total of the volume of trading that takes place in a security:

• For any day in which the close of the security is higher than its previous close, the total volume of trading for that day is added to the on-balance volume total for that security.
• For any day in which the close of the security is lower than its previous close, the total volume of trading for that day is subtracted from the on-balance volume total for that security.
• If the close of the security is the same as its previous close, the on-balance volume for that day does not change.

Who Created the OBV Indicator?

Joseph Granville is considered to be the father of the OBV indicator and is one of the most widely recognized experts and writers regarding market analysis. Granville introduced OBV in his book The New Key to Stock Market Profits and suggested that volume is the underlying force that drives stock prices.

In addition, Granville theorized that the volume of trading would frequently change before price changes would appear on the price chart. OBV is currently one of the most widely used volume indicators in trading across all markets, including:

• Forex Market
• Stock Market
• Commodity Market
• Cryptocurrency Market
• Market Indices

The Psychology Behind OBV and Smart Money Activity

One of the reasons that OBV has remained relevant for so long (over 100 years) is that it demonstrates a foundational concept of the financial markets: large participants in the market can’t hide their trades forever.

Typically, large transactions executed by institutional traders, hedge funds, banks or other asset managers typically involve millions of dollars’ worth of trades. Since entering or exiting such a large block would have a drastic impact on the marketplace, these participants create or liquidate their positions progressively over time, resulting in a pattern of unusual volume prior to a major price fluctuation being visible.

The concept of “price follows volume” is well-established. Professional investors begin to accumulate assets, they may begin accumulating an asset by drastically increasing the volume of trading but not the price of that asset.

A consistently rising OBV with no significant increase in price typically suggests a large number of institutional investors are building their positions. Conversely, if the price is rallying but the OBV is falling, this is likely indicative of institutional distribution and a weakening market.

The timing difference between institutional and retail traders creates trading opportunities for traders who have an understanding of market volume dynamics. Rather than chasing prices, the trader can use the OBV to find areas of potential market sentiment changes on an earlier basis.

Because of this, many pros view OBV as both a pure volume indicator and also an indicator of the degree of conviction behind price movements. While price may move on short-term speculation, the longer term trends in volume will provide insight into where the majority of players are placing their money.

How Is the OBV Indicator Calculated?

The OBV calculation is very straightforward:

• If the price at the end of today is higher than the price at the end of yesterday: The OBV will equal the OBV from yesterday (the previous OBV) plus today’s volume of transactions.
• If the price at the end of today is lower than the price at the end of yesterday: The OBV will equal the OBV from yesterday (the previous OBV) minus today’s volume of transactions.
• If the price at the end of today is the same as the price at the end of yesterday: The OBV will equal the OBV from yesterday (the previous OBV).

It does not matter what the actual OBV number is. What does matter are the following items:

• The direction of the OBV line
• How the OBV line moves in relationship to the current price action
• Divergence between the OBV and current price action

Some of the newer trading platforms automatically calculate the indicator, so traders do not have to do any manual calculations.

Why Is Volume Important in Trading?

Volume reflects how much money is being used in the market. In order to make a transaction, there must be a buyer and there must be a seller. When there is a high amount of volume, this suggests that there is greater conviction behind the direction or strength of the move. High level of volume on transactions usually indicate:

• Institutional buying or selling
• Confirmation of the direction of price movement
• Bullish or bearish market sentiment

Low levels of volume on transactions usually indicate:

• Weak price movement
• Limited conviction to hold the position
• Reversal in direction

This is why many professional traders use both volume analysis and technical or fundamental analysis together. Reliable resources for daily analysis of overall market trends through quality market analysis can help traders determine if the volume activity is consistent with overall market conditions.

How to Add the OBV Indicator in MetaTrader 5

To Append OBV in a MetaTrader 5:

• Open the Chart for trading.
• Select the “Insert” option
• Select Indicators
• Click the “Volumes” Section
• Select the “On Balance Volume” and
• Set Preferred Settings

OBV will show in an area separate from the Chart once you are done. The majority of traders who use STP Trading MetaTrader 5 make use of the OBV since it clearly illustrates the volume-momentum from a visual standpoint without creating clutter on charts.

How to Read the OBV Indicator Correctly

It is much more Important to understand the Interpretation of the OBV versus the Formula. The OBV offers insight by Comparing:

Rising OBV Indicator

When the price and OBV are both on the rise, the trend is generally considered a healthy trend. Rising OBV indicates an increase in positive activity which means:

• Accumulation
• Increased Market Interest
• An Increase in Trend Continuation Upwards

Falling OBV Indicator

When both the price and OBV are both falling, It has been confirmed as a bearish momentum. Falling OBV indicates increased negative activity which means:

• Distribution
• Sales by the Institutional Trader
• Decrease in the Bullish Momentum

Flat OBV Indicator

Flat OBV indicates:

• Market consolidation
• Balanced buying and selling pressure
• Lack of a clear directional bias

This environment may not represent good trading opportunities.

OBV Divergence, The Most Powerful Signal

Divergence with On-Balance Volume indicator can provide very useful clues about changes in price, volume and market sentiment. When price and volume diverge it means that price is not supported by an equal amount of volume, and, as a result, it indicates that market sentiment may be changing.

Divergence with On-Balance Volume is a leading signal showing that market participants are beginning to lose faith in the continuation of the current price trend (up or down) before price changes occur.

For instance, if a market continues to make higher highs and buyers continue to increase their buying interest, there is a feeling of bullish market sentiment. However, if buyers or volume have not also confirmed each of the higher highs, it indicates a decrease in the number of market participants or less volume supporting the advancing of the price change.

Thus, the market could be more likely to experience either a weakening of the trend or a reversal from the previous uptrend to a downtrend. Panic selling often drives prices to even lower levels during extended periods of declining prices, and if OBV starts to stabilize or improve while prices continue to decline then there is a strong possibility that selling pressure is being absorbed by larger buying institutions.

This happens frequently at major market bottoms. Traders should not treat divergences from OBV as immediate trade signals right away. In fact, utilizing divergence is most useful when coupled with other confirmation signals such as support & resistance areas, candlestick reversal patterns, breakouts from trendlines, or momentum breakout indicators.

The highest probability setups will occur when multiple technical factors align with an OBV divergence. When analyzing OBV divergences, another thing to keep in mind is what timeframes you are using for analysis.

Divergences identified on higher timeframes tend to have more significance than those that develop on lower timeframes. In addition, longer-term divergences often reflect a broader institutional involvement and may indicate forthcoming large moves within the overall market.

When utilized properly, OBV divergence can provide a trader with an early warning system; thus allowing traders to predict turning points in advance of the market.

Best OBV Trading Strategies

The On-Balance Volume (OBV) is more useful. When you use it as part of a complete trading system, it’s much more useful as a signal to trade than relying on it by itself. OBV is often combined with other technical indicators to validate the direction of the market before deciding to enter trades.

OBV is one of the best means to use to determine whether a breakout is genuine or not, and if it should be entered. A breakout with rising OBV indicates significant market participation and has a higher likelihood of continuing.

Conversely, a breakout with stagnant or declining OBV may lack sufficient conviction and hence isn’t recommended to trade.

OBV Trend Confirmation Strategy

This strategy can be applied to daily charts as well as intraday charts. When price and OBV show an identical breakout from a chart pattern, price and volume are in agreement and the breakout is anticipated to occur.

Trading participants should expect the price to follow after the volume has confirmed the breakouts. As a result, the OBV volume pattern served to assist in confirming the breakouts of prices for both stocks by creating an opportunity to participate in the stock market.

OBV and Support/Resistance Strategy

Volume confirms the importance of support & resistance zones. If price breaks resistance with rising OBV, it indicates a stronger breakout than with a weak volume breakout.

Multi-Timeframe Analysis Strategy

Many experienced traders look at OBV on multiple timeframes. A bullish OBV signal from a lower timeframe is more valid when the overall OBV trend from a higher timeframe is also bullish.

This validates short-term trades with long-term direction to keep you from trading against the dominant momentum of the market.

OBV and Price Structure Strategy

Traders commonly mix OBV and price structure analysis to determine the best time to enter and exit trades. For instance, a bullish price structure like a flag or triangle may indicate an increased chance of a positive breakout if OBV continues upward.

How Institutional Traders Use OBV

While not an absolute measurement, institutional traders usually focus on measuring money flows into or out of an asset, rather than just trading based on price movements. Many large financial institutions execute orders of such magnitude that they rely heavily on indicators based on volume to confirm shifts in liquidity.

An example of this is through volume and consolidation cycles. When price is range-bound and OBV is increasing, it can be interpreted as accumulation by institutions; conversely, if OBV is decreasing when price is in consolidation, it indicates professional money is exiting before a major decline.

Another way institutions use OBV is by establishing conviction in the market around major releases and announcements. If the announcement was made by a central bank or significant economic data has been released, the movement of price accompanied with a strong reaction from OBV could signify market participants truly support the price movement.

Therefore, it gives additional confirmation of long-term trends that are meaningful versus short-term market volatility. Most institutions use OBV in conjunction with other analysis, such as examining order flows, liquidity and market structure. OBV acts as a confirming indicator for determining the strength behind movements in the market.

OBV Indicator in Forex Trading

Forex traders have been asking about whether OBV works in decentralized markets.

Brokers will provide tick volume, which tracks the frequency of price movements and the level of activity in the marketplace; this is often referred to as a surrogate for trade volume.

However, there have been studies demonstrating a strong correlation between tick volume and actual trade volume. Due to this, many forex traders use OBV to:

• Confirm trend direction
• Identify trend reversals
• Validate breakout signals

Traders who use professional trading account types and structures will typically incorporate volume analysis into their overall trading approach.

Real OBV Trading Examples

Example: Bullish Divergence (Before the Trend Change)

Let’s say EUR/USD moves down from 1.1200 to 1.1000, then again down to 1.0950. At first glance, it appears that the market is bearish, since there are continued lower lows. But at the same time that EUR/USD reached its second lower low, the OBV has formed a higher low.

This divergence is a suggestion that selling pressure is decreasing even though the market is still moving down. Days later, the buyers regain strength and EUR/USD begins to trend upward.

The OBV was an early warning that the bearish momentum was already getting weaker before it showed clearly in the chart.

OBV Indicator in Cryptocurrency Trading

OBV has gained popularity with crypto traders due to transparent volume available from exchange sources. OBV can also help identify:

• Accumulation by Whales
• Institutional buying activity
• Distribution phases
• Trend continuation

Given the fact that crypto markets often operate through strong emotional responses, traders will benefit from using volume analysis to provide insight many times before significant price movements occur.

How to Spot False Breakouts with OBV

False breakouts occur when the price reaches a new level; however, there are not enough traders in this area to hold that new level or continue to drive the price higher (or lower). The On-Balance Volume (OBV) can indicate when there is a buying or selling or lack thereof to help in identifying these types of traps.

If the price breaks above resistance while the OBV remains flat or fails to make a new high, the breakout may lack sufficient buying pressure. Then this means that there is increasing buying pressure on the asset at the same time pricing is rising.

In addition, if price breaks to the upside and OBV line stays flat then that may be an indication that because of low volume that the breakout may be susceptible to failure. On the other hand, if the price breaks below a support level while the OBV is weak and well below trend line, then this means that sellers may not have enough conviction to keep the price lower.

Therefore there may be a quick reversal breakout back into the original trading range. A good way to determine whether or not a breakout is valid is to compare the trend of the OBV to the structure of the breakout.

If the price and the OBV break their respective resistance-levels together, that breakout is more valid. If the price breaks by itself and the OBV lags behind the price, traders are encouraged to wait for additional confirmation of the validity of the breakout before entering into a trade.

How to Backtest OBV

A key element of developing a successful trading system is backtesting, which is used to determine whether a given methodology has consistently generated results over time. Traders can analyze their historic performance with empirical data rather than relying on assumptions or estimates made by third parties.

The initial step in backtesting is the establishment of rules for entering and exiting positions. One example might be a long position once the price range exceeds the upper trend line, and the OBV reaches a new peak at the same time.

Conditions for exiting from a position should also be established prior to testing. The next step in the process is to test a large enough sample of historic data to provide a valid statement of what has occurred in the past.

Only testing during a strong trend may create false expectations for performance; however, if both strong and weak trends as well as consolidating ranges are included in the sample size, the findings will provide a more accurate assessment of how OBV performs overall.

At each point during the backtesting process, key metrics of successful performance must be reported, including the win or loss percentage, average profit or loss versus average loss for each profitable trade, overall return on investment, and total profit.

By measuring these statistics, a trader can determine if the strategy employed has any statistically measurable advantage. Advanced traders usually use trade platforms using strategy testers to increase their ability to develop and test past strategies.

Physical analysis of the charts for backtesting without the use of trading software can also produce significant insight into OBV performance in various market conditions.

OBV vs Volume Indicator: What’s the Difference?

Common Mistakes When Using OBV

Why Risk Management Matters When Trading with OBV

While OBV trading setups can yield impressive results; they do not guarantee success. To Trade effectively, successful traders combine:

• Stop-Loss Placement
• Position Size
• Portfolio Diversification
• Hedging Strategies

Using appropriate hedging strategy reduces exposure during volatile markets & protects one’s trading capital.

Can OBV Be Used for Social Trading?

Definitely, many traders utilize the OBV indicator to develop a copy trading strategy or social trading system. This can provide beginners with the ability to learn how top traders are using volume analysis to identify solid trade setups.

There are many platforms available that offer social trading services and provide traders with the capability to view and copy the way top traders are entering and exiting positions, while continuing to develop their individual trading skills.

Combine OBV With Other Indicators

Although the volume is valuable insight into the dynamics of volume, if you combine this with other complementary Forex indicators, you can build a more complete picture to aid in your trading.

OBV and Moving Averages

Moving averages act as a tool to provide directionality of a trend, while OBV assists in determining if there is sufficient volume behind the trend. This combination can be beneficial for both directional trend following type strategies.

OBV and RSI

The relative strength index measures both momentum & market exhaustion levels. When OBV confirms RSI signal, it further strengthens the trader’s conviction with regards to potential validity of that particular setup.

OBV and MACD

MACD is used to identify a shift in either momentum or trend direction. By specifically looking for MACD crossovers while looking for confirmation from OBV, traders can filter out weaker signal trades.

Combining OBV with Professional Market Forecasts

No matter how good an indicator may be, it cannot accurately predict future price movements. However, historically, traders have made the best trading decisions by combining the following tools: Technical indicators, volume indicators, market sentiment and economic data.

For that reason, many traders will use OBV signals along with professional market outlooks and Forex forecasts like STP Trading market predictions to anticipate the future direction of the market.

Advantages and Disadvantages of OBV

OBV has both pros and cons for traders due to the nature of technical indicators.

Recommendations on Trading with the OBV

Discipline and context are key factors in successfully using OBV. Rather than taking every move in OBV as a signal to trade, traders should find high-quality setups that meet multiple criteria.

One recommendation is to follow higher time frames. The OBV values on daily and weekly charts often provide more value because of the reduction of “noise” in comparison to lower time frames.

Traders need to look at the overall market environment; OBV will generally work best in a trending environment, where volume participation is consistent with either continued buying or selling, as opposed to when there is a lot of “choppy” trading or low liquidity.

Traders should also utilize sound risk management practices when trading based on OBV signals, as even a strong OBV signal can fail. Proper position sizing and establishing stop or loss orders are essential for every trade.

Turn Volume Into Trading Insight with STP Trading

The on-balance volume (OBV) technical indicator can be one of the best indicators for determining the relationship between price change and participant buying/selling activity. It helps traders identify hidden buying and selling pressure, confirm trend strength, detect potential reversals, and anticipate future price movement; therefore, OBV offers an additional layer of market insight that cannot be obtained from price action alone.

Like all technical indicators, the obv performs better with effective risk management, market analysis, and a safe trading environment. STP Trading allows you to trade on obv effectively by providing all necessary resources, including advanced charting capabilities and metatrader 5 software, extensive market analysis, and flexible account types for all experience levels, when trading foreign currency pairs, commodities, indices, and cryptocurrencies.
