The On Balance Volume (OBV) is a technical analysis indicator designed to measure buying and selling pressure by analyzing volume flow. Developed by Joseph Granville in 1963, OBV was one of the pioneering tools to quantify positive and negative volume movements. This guide explores OBV's calculation, interpretation, and practical strategies for traders.
Key Questions About OBV
What is On Balance Volume?
OBV is a momentum-based indicator that correlates volume flow with price changes to identify major market movements. It accumulates volume on up days and subtracts volume on down days.
How to interpret OBV?
- Uptrend confirmation: Rising OBV alongside higher price peaks.
- Downtrend signal: Falling OBV with lower price troughs.
- Divergence: Price and OBV moving inversely often foreshadow reversals.
Is OBV reliable?
Yes. OBV effectively gauges buying/selling pressure and momentum shifts, especially when combined with price trends.
Calculating OBV
The formula adapts based on price movements:
- Price ↑:
Current OBV = Previous OBV + Current Volume - Price ↓:
Current OBV = Previous OBV – Current Volume - Price unchanged: OBV remains the same.
