Overview

On Balance Volume (OBV) is a technical analysis indicator used to measure buying and selling pressure by tracking the volume of trades. It was developed by Joe Granville in the 1960s.

Calculation

To calculate OBV, the following steps are taken:

  1. If the closing price is higher than the previous day’s closing price, add the volume to the OBV.
  2. If the closing price is lower than the previous day’s closing price, subtract the volume from the OBV.
  3. If the closing price is unchanged from the previous day’s closing price, leave the OBV unchanged.

Interpretation

OBV is used to identify trends and confirm price movements. When the OBV is rising, it indicates that buying pressure is increasing and there is upward momentum in the market. Conversely, when the OBV is falling, it indicates that selling pressure is increasing and there is downward momentum in the market.

Advantages

  • OBV provides an early warning of possible trend changes.
  • It can be used on any time frame.
  • OBV can be used to confirm trends and price movements.

Disadvantages

  • OBV may generate false signals in choppy markets.
  • It may not work well with stocks that have low trading volumes.
  • OBV does not take into account the price level of the security being analyzed.

Overview

The On Balance Volume (OBV) is a technical indicator that measures buying and selling pressure based on trading volumes. OBV calculates the cumulative total volume of an asset by adding or subtracting each day’s volume, depending on whether the closing price is higher or lower than the previous day’s closing price.

Calculation

To calculate the OBV, you need to follow these steps:

  1. Start with an initial value of 0 for the OBV.
  2. If the closing price is higher than the previous day’s closing price, add today’s volume to the OBV.
  3. If the closing price is lower than the previous day’s closing price, subtract today’s volume from the OBV.
  4. If the closing price is the same as the previous day’s closing price, do not change the OBV.
  5. Repeat this process for each trading day.

Interpretation

The OBV can be used to confirm price trends or to identify potential reversals. A rising OBV indicates that buying pressure is increasing, while a falling OBV indicates that selling pressure is increasing. If the OBV is moving in the opposite direction of the price, it can signal a potential reversal. However, it is important to use other technical indicators to confirm the signals provided by OBV.

Advantages of using OBV

  • Simple and easy to calculate.
  • Provides insight into the strength of trends.
  • Can be used in combination with other technical indicators to confirm trading signals.
  • Can be applied to any asset that has volume data available.

Disadvantages of using OBV

  • Only takes into account volume data, not price data.
  • Can be affected by outliers or abnormal trading volumes.
  • May provide false signals during periods of low trading volumes.
  • Not suitable as a stand-alone indicator for making trading decisions

Definition of On-Balance Volume (OBV)

On-Balance Volume (OBV) is a technical analysis indicator used by traders to measure buying and selling pressure.

The OBV indicator was developed by Joseph Granville in the 1960s. It takes into account the volume of trades during periods of price change, and it provides a more complete picture of the market than traditional price-based indicators.

Formula for On-Balance Volume (OBV)

The calculation of OBV is based on the principle that changes in volume often precede changes in price. The OBV formula is:

  • If today’s closing price is higher than yesterday’s closing price, then: OBV = previous OBV + today’s volume
  • If today’s closing price is lower than yesterday’s closing price, then: OBV = previous OBV – today’s volume
  • If today’s closing price is the same as yesterday’s closing price, then: OBV = previous OBV

Uses of On-Balance Volume (OBV) as Indicator

OBV can be used to identify trends and momentum in the market, as well as potential reversals in those trends. Here are some common uses of OBV:

  • OBV can be used to confirm the direction of a trend. If the OBV line is moving in the same direction as the price, it confirms the trend. If the OBV line is moving in the opposite direction from the price, it may signal a potential trend reversal.
  • OBV can be used to identify divergences between the price and volume. If the price is making higher highs but the OBV line is making lower highs, it may signal a bearish divergence. Conversely, if the price is making lower lows but the OBV line is making higher lows, it may signal a bullish divergence.
  • OBV can be used in conjunction with other technical analysis indicators to confirm trade signals. For example, if a chart shows a bullish trend based on moving averages and the OBV line is also moving up, it can be a strong signal to go long.

On-Balance Volume (OBV) Definition

On-Balance Volume (OBV) is a technical analysis indicator that measures positive and negative volume flow. It was developed by Joseph Granville in the 1960s and is used to determine whether there is buying or selling pressure on an asset.

OBV takes into account the volume of trades made during a specific period and adds or subtracts the volume depending on whether the price closes higher or lower than the previous day’s closing price.

OBV Formula

The formula for calculating OBV is:

OBV = Previous OBV + Current Volume if Closing Price > Previous Closing Price

OBV = Previous OBV – Current Volume if Closing Price < Previous Closing Price

OBV = Previous OBV if Closing Price = Previous Closing Price

Where:

  • Previous OBV: OBV value of the previous day
  • Current Volume: trading volume of the current day
  • Closing Price: closing price of the current day

Uses of OBV as Indicator

OBV is used by traders and analysts to confirm price trends and identify potential trend reversals. When prices are rising and OBV is also rising, it indicates that buying pressure is strong and the uptrend is likely to continue. Similarly, when prices are falling and OBV is also falling, it indicates that selling pressure is strong and the downtrend is likely to continue.

OBV can also be used to identify divergences between volume and price, which can signal a potential reversal in the trend. For example, if prices are rising but OBV is falling, it may indicate that buying pressure is weakening and a trend reversal is possible.

Overall, OBV is a useful tool for traders and analysts to incorporate into their technical analysis strategy as it provides insight into volume and price movements of an asset.
