The On Balance Volume (OBV) indicator is a powerful tool for traders and investors seeking to gauge the strength or weakness of a price trend. This technical analysis indicator uses volume to confirm price movements, providing valuable insights into potential future price changes.
What Is the On Balance Volume Indicator?
Developed by Joe Granville in the 1960s, the OBV indicator measures the flow of volume in relation to price movements. Its core premise: volume precedes price.
Key Calculation Rules:
- Higher close: Current volume added to OBV.
- Lower close: Current volume subtracted from OBV.
- Unchanged close: OBV remains the same.

How the On Balance Volume Indicator Works
Steps to Calculate OBV:

Key Concepts in OBV Strategy
1. OBV and Trend Confirmation
- Uptrend: Rising OBV + rising price = strong buying pressure.
- Downtrend: Falling OBV + falling price = strong selling pressure.
2. OBV Divergence
- Bullish divergence: Price makes lower lows; OBV makes higher lows.
- Bearish divergence: Price makes higher highs; OBV makes lower highs.
3. OBV Breakouts
- Bullish breakout: OBV breaks resistance = uptrend likely.
- Bearish breakout: OBV breaks support = downtrend likely.
Using OBV in Trading
1. Combine OBV with Price Patterns
- Example: Bullish flag pattern + rising OBV = high-probability breakout.
2. Pair OBV with Moving Averages
- Signal: OBV crosses above/below MA = buy/sell opportunity.
3. Integrate with Other Indicators
