Ever wondered how to gauge the true strength behind a price movement? Enter On-Balance Volume (OBV), a technical analysis indicator developed by Joseph Granville in the 1960s. OBV combines price and volume to measure buying and selling pressure, acting as the market’s pulse to reveal insights hidden by price alone.
Overview of OBV
Definition and Purpose
OBV tracks cumulative volume flow by:
- Adding volume on days when prices close higher.
- Subtracting volume on days when prices close lower.
The resulting line helps traders determine if volume supports the price trend. For example:
- Bullish Signal: Rising OBV + Rising price = Strong buying pressure.
- Bearish Divergence: Rising price + Falling OBV = Weak trend conviction.
Key Features
- Trend Confirmation: Validates price movements with volume.
- Divergence Detection: Flags potential reversals before price shifts.
- Breakout Validation: Identifies accumulation/distribution phases.

Trading Strategies with OBV
1. Trend Confirmation
- Rule: Enter long if OBV rises alongside price; short if both decline.
- Example: Tech stock uptrend with rising OBV → Hold or add positions.
2. Divergence Trading

- Bearish Divergence: Price makes higher highs; OBV makes lower highs → Sell.
3. Breakout Strategy

- Example: Financial stock breaks resistance with rising OBV → Enter long.
4. Combining OBV with Other Indicators
- RSI: Confirm OBV signals with RSI overbought/oversold levels.
- MACD: Use MACD crossovers to validate OBV trends.
