OBV Indicator Demystified: How to Use It Effectively

The On-Balance Volume (OBV) indicator is a powerful tool in technical analysis used to gauge the strength of price movements in a particular asset. Developed by Joseph Granville in the 1960s, OBV helps traders identify potential trend reversals, confirm price trends, and spot divergences between price and volume movements. Understanding how to effectively utilize obv indicator can significantly enhance a trader’s ability to make informed decisions in the market.

What is OBV?

OBV is based on the principle that volume precedes price movement. It accumulates volume based on whether the price closes higher or lower than the previous close. If the closing price is higher than the previous close, the volume for that day is added to the OBV. Conversely, if the closing price is lower, the volume is subtracted. This cumulative total creates the OBV line.

Interpreting OBV

The OBV line acts as a leading indicator, often diverging from price movements. When the OBV line is trending upwards while prices remain relatively flat or declining, it suggests underlying accumulation and indicates potential upward price movement in the future. Conversely, if the OBV line is trending downwards while prices are flat or rising, it signals distribution and foreshadows potential downward price movement.

Using OBV for Confirmation

Traders often use OBV to confirm price trends. If the OBV line is moving in the same direction as the price trend, it provides confirmation that the trend is strong and likely to continue. However, if the OBV line diverges from the price trend, it may indicate weakening momentum and potential trend reversal.

Spotting Divergences

One of the most valuable aspects of OBV is its ability to identify divergences between price and volume movements. For example, if the price of an asset is making higher highs, but the OBV line is making lower highs, it suggests that buying pressure is weakening despite the rising prices, potentially signaling an impending reversal.


The OBV indicator is a versatile tool that can provide valuable insights into market trends and potential reversals. By understanding how to interpret OBV and integrate it into your trading strategy, you can make more informed decisions and improve your overall trading performance. However, like any technical indicator, OBV should be used in conjunction with other analysis techniques for optimal results.
