On-Balance Volume (OBV) is a technical analysis indicator that measures positive and negative volume flow to predict the future direction of the asset's price. Developed by Joseph Granville, it focuses on the cumulative volume traded during a specific time period.
OBV is based on the notion that volume precedes price movement. It assumes that when volume increases significantly, it indicates a strong buying or selling pressure that can influence the future price of the asset. By analyzing the relationship between volume and price, traders attempt to gain insights into the overall market trend.
To interpret OBV, traders first examine its direction. If OBV is rising, it suggests that the buying pressure is outweighing the selling pressure, indicating a bullish trend. Conversely, if OBV is falling, it implies that selling pressure is dominating, indicating a bearish trend. Trend confirmations can be made by comparing OBV with the corresponding price chart.
Additionally, traders look for divergences between OBV and the price movement. A bullish divergence occurs when the price is declining while OBV is rising, suggesting a potential trend reversal to the upside. On the other hand, a bearish divergence occurs when the price is rising while OBV is falling, indicating a possible trend reversal to the downside.
It is also important to analyze OBV in relation to support and resistance levels. If OBV breaks out of a range along with the price, it confirms the validity of the breakout. If OBV fails to confirm a new high or low by the price, it may suggest a weak trend or an upcoming reversal.
Lastly, traders often employ moving averages on OBV to identify potential trend changes more easily. A rising OBV line above its moving average indicates a bullish signal, while a falling OBV line below its moving average suggests a bearish signal.
Overall, interpreting OBV involves assessing its direction, divergences, relation to support/resistance levels, and interaction with moving averages. By understanding these principles, traders can incorporate OBV into their analysis and make more informed trading decisions.

How to calculate On-Balance Volume (OBV)?
To calculate the On-Balance Volume (OBV), follow these steps:
- Start by setting the initial OBV value as zero.
- Compare the closing price of the current period with the closing price of the previous period.
- If the current closing price is higher than the previous closing price, add the trading volume of the current period to the OBV.
- If the current closing price is lower than the previous closing price, subtract the trading volume of the current period from the OBV.
- If the current closing price is the same as the previous closing price, leave the OBV unchanged.
- Repeat this process for each period to calculate the cumulative OBV.
Here's an example to illustrate the calculation:
Date Closing Price Volume OBV
Jan 1 $10 1000 0 Jan 2 $12 1500 1500 (volume added as price increased) Jan 3 $8 2000 -500 (volume subtracted as price decreased) Jan 4 $10 1200 -500 (OBV unchanged as price remained the same)
Note: The OBV is usually displayed as a line graph that tracks the cumulative volume, allowing traders to identify trends and confirm price movements.
What is the significance of volume in OBV analysis?
Volume is a key component in On-Balance Volume (OBV) analysis because it helps to indicate the strength of a price trend. OBV is a technical indicator that measures the cumulative buying and selling pressure based on changes in volume.
The significance of volume in OBV analysis can be summarized as follows:
- Confirmation of price trend: OBV analysis confirms the price trend by comparing the trading volume with the direction of the price movement. When the OBV line rises along with an increasing price trend, it indicates that buying volume is supporting the upward movement, suggesting a strong bullish trend. Conversely, when the OBV line falls while prices are declining, it suggests a strong bearish trend.
- Divergence signals: Volume can help identify divergences between price and OBV, which can provide early warning signals for trend reversals. For example, if prices are rising, but OBV is falling, it may indicate weakening buying pressure and potential weakness in the trend. Similarly, if prices are falling, but OBV is rising, it may signal an upcoming bullish reversal.
- Breakout confirmation: Volume can help confirm breakouts and support or resistance levels. When prices break above a resistance level with high volume, it suggests a strong breakout and confirms the validity of the upward move. Conversely, if prices break below a support level with high volume, it confirms the strength of the downward move.
- Volume patterns and trends: Analysis of volume patterns, such as volume spikes, can provide insights into market sentiment and investor behavior. Unusual volume spikes often occur during significant news events or market turning points, indicating increased market participation and potential trend reversals.
Overall, volume analysis in OBV can help traders and technical analysts to understand the underlying market dynamics, validate price trends, and identify potential trading opportunities.
What is the relationship between OBV and trading volume?
The On-Balance Volume (OBV) indicator is a technical analysis tool that measures buying and selling pressure in the financial markets. It is based on the relationship between OBV and trading volume.
OBV is calculated by adding the volume on days when the price closes higher and subtracting the volume on days when the price closes lower. As a result, OBV typically reflects the cumulative total of trading volume over a given period.
The relationship between OBV and trading volume is that OBV takes into account both the direction of price movement and the trading volume associated with that movement. It helps to identify the strength of buying or selling pressure in a security.
When the OBV line is trending upwards, it suggests that positive volume flow (buying pressure) is increasing, indicating potential strength in the price movement. Conversely, a downward trend in OBV indicates that negative volume flow (selling pressure) is increasing, which might indicate weakness in price.
Traders often use OBV to confirm the strength of a trend or identify potential reversals. If there is a divergence between the OBV and the price, where OBV is moving in the opposite direction to the price, it can signal a possible change in trend direction.
In summary, OBV and trading volume have a relationship where OBV incorporates trading volume to provide insights into the strength of buying and selling pressure in a security, helping traders make informed decisions.
What are the indications of hidden divergence in OBV?
Hidden divergence is a technical analysis tool used to identify trend reversals. In the case of On Balance Volume (OBV), hidden divergence occurs when there is a discrepancy between the direction of OBV and price movement. The indications of hidden divergence in OBV include:
- Bullish Hidden Divergence: It occurs during a downtrend when the price is making lower lows but the OBV is making higher lows. This suggests that the selling pressure is decreasing, even though the price is still declining. It is considered a bullish signal that may indicate an upcoming trend reversal or a continuation of the current uptrend.
- Bearish Hidden Divergence: It occurs during an uptrend when the price is making higher highs but the OBV is making lower highs. This suggests that buying pressure is diminishing, despite the price continuing to rise. It is considered a bearish signal that may indicate an upcoming trend reversal or a continuation of the current downtrend.
When identifying hidden divergence in OBV, traders typically compare the trend lines connecting the highs and lows of the OBV with the corresponding trend lines of the price action to determine the presence of hidden divergence.
