On-Balance Volume (OBV) is a cornerstone technical analysis indicator that evaluates volume flow relative to price movements. Created by Joseph Granville in the 1960s, it remains a vital tool for traders analyzing market trends, validating price momentum, and forecasting potential reversals through volume dynamics.
This guide dives deep into OBV strategies—from foundational principles to advanced trading applications—to empower your market decisions.
What Is On-Balance Volume (OBV)?
On-Balance Volume is a momentum indicator that correlates volume changes with price direction. Its core premise: volume drives price action.
- Bullish Signal: Rising prices with increasing volume add to OBV.
- Bearish Signal: Falling prices subtract volume from OBV.
- Neutral: No change if prices remain flat.
Granville’s theory posits that volume accumulation/distribution often precedes price shifts, making OBV a leading indicator.
How to Calculate OBV
The formula is simple but powerful:
| Condition | OBV Adjustment |
|------------------------------------|-----------------------------|
| Today’s close > Yesterday’s close | OBV + Today’s volume |
| Today’s close < Yesterday’s close | OBV - Today’s volume |
| Today’s close = Yesterday’s close | OBV unchanged |
Example:
Day 1: Close = $50, Volume = 10,000 → OBV = 10,000
Day 2: Close = $52 (+), Volume = 12,000 → OBV = 22,000
Day 3: Close = $51 (-), Volume = 8,000 → OBV = 14,000
Key Trading Strategies Using OBV
1. Trend Confirmation
- Uptrend Validated: Rising OBV confirms bullish momentum.
- Downtrend Confirmed: Declining OBV aligns with bearish trends.
- Divergence Alert: If prices rise but OBV falls (or vice versa), expect a potential reversal.

2. Breakout Verification
- Breakout with High Volume: OBV spikes support genuine breakouts.
- Low-Volume Breakout: Suspect false breaks if OBV stagnates.
3. Support/Resistance Levels
- OBV often mirrors price support/resistance. Use it to spot accumulation (buying pressure) or distribution (selling pressure) zones.
Optimizing OBV for Modern Markets
Combine with Other Indicators
- Moving Averages: Filter OBV signals with a 20-day or 50-day MA.
- RSI: Pair OBV with Relative Strength Index for overbought/oversold clarity.
Timeframe Flexibility
- Swing Traders: Daily/weekly OBV for trend analysis.
- Day Traders: 1-hour/15-minute charts for intraday signals.
FAQs: On-Balance Volume Demystified
Q1: Can OBV predict exact price reversals?
A: OBV flags potential reversals via divergence but isn’t infallible. Confirm with price action.
Q2: How does OBV differ from Accumulation/Distribution Line?
A: Both track volume-price relationships, but OBV uses daily closes, while A/D incorporates intraday highs/lows.
Q3: Is OBV effective in sideways markets?
A: Limited utility—volume fluctuations lack clear trends. Focus on breakout/breakout scenarios.
Q4: Best assets for OBV strategies?
A: Highly liquid stocks, forex pairs, or crypto (e.g., BTC/USD) with consistent volume data.
