OBV Divergence: Spotting Reversal Signals with On-Balance Volume

1. Introduction to OBV Divergence

Trading success hinges on identifying potential reversals early. The On-Balance Volume (OBV) divergence is a powerful momentum indicator that leverages volume trends to predict price movements. OBV tracks cumulative buying/selling pressure by adding volume on up days and subtracting it on down days.

Key Insights:

• Bullish Divergence: Price makes lower lows while OBV forms higher lows (buying pressure surges).
• Bearish Divergence: Price makes higher highs while OBV shows lower highs (selling pressure intensifies).
• Hidden Divergence: Suggests trend continuation despite price fluctuations.

2. Understanding On-Balance Volume (OBV)

OBV quantifies market sentiment by correlating volume with price direction:

• Rising OBV = Strong buying interest (confirms uptrends).
• Falling OBV = Strong selling interest (confirms downtrends).

Calculation Example:

• If Stock A rises from $10 to $12 on 10K volume, OBV adds +10K.
• If it then drops to $11 on 8K volume, OBV subtracts -8K.

3. Calculating OBV

Formula:

1. Up Day: OBV = Previous OBV + Current Volume.
2. Down Day: OBV = Previous OBV - Current Volume.
3. Flat Day: OBV remains unchanged.

Pro Tip: Use OBV alongside trendlines—rising OBV trendlines during price declines signal accumulation.

4. Types of OBV Divergence

| Type | Price Action | OBV Action | Signal |
|--------------------|--------------------|-------------------|-----------------|
| Bullish | Lower Lows | Higher Lows | Potential Rally |
| Bearish | Higher Highs | Lower Highs | Potential Drop |
| Hidden Bullish | Higher Lows | Lower Lows | Continuation |

Example: Bitcoin’s 2018 price lows vs. rising OBV foreshadowed its 2019 rally.

5. Spotting OBV Divergence on Charts

Steps:

1. Identify Trends: Note higher highs/lows in price and OBV.
2. Draw Lines: Connect peaks/troughs for visual divergence.
3. Confirm with RSI/MACD: Strengthen signals with overbought/oversold conditions.

Chart Tip: Use logarithmic scales for long-term analysis.

6. Trading Strategies

Strategy 1: Reversal Confirmation

• Entry: Bullish divergence + RSI oversold.

Strategy 2: Trend Continuation
