On-Balance Volume (OBV) Pattern Recognition

What is On-Balance Volume (OBV)?

The On-Balance Volume (OBV) is a bullish continuation pattern discovered by William O'Neil. It forms when a stock consolidates in a U-shaped "cup" over 7-65 weeks, then pulls back slightly in a "handle" before breaking out to new highs.

This pattern signals institutional accumulation. The cup shows patient buying, the handle shakes out weak hands, and the breakout confirms strong demand. Success rate: 65-70% when all criteria are met.

Key Insight: On-Balance Volume (OBV) works best on stocks with strong fundamentals in uptrends. Avoid in bear markets or on weak stocks.

Cup Formation Requirements

1. Cup Depth (12-33%)

Cup Depth % = [(Left Rim - Bottom) / Left Rim] × 100

Ideal: 12-33% - Healthy correction
Too Shallow (< 12%): Weak pattern, low profit potential
Too Deep (> 33%): Risky, may indicate weakness

2. Cup Duration (7-65 weeks)

Minimum: 7 weeks - Allows proper base building
Ideal: 3-6 months - Most reliable
Maximum: 65 weeks - Beyond this, pattern loses relevance

3. Cup Shape (U not V)

U-Shape: Gradual decline and rise, institutional accumulation
V-Shape: Sharp drop and recovery, too volatile, avoid
Bottom: Should be rounded, not sharp

Handle Formation

Handle Requirements

Duration: 1-4 weeks - Brief consolidation
Depth: < 15% of cup depth - Shallow pullback
Position: Upper half of cup - Shows strength
Shape: Downward drift or flag - Not sharp drop
Volume: Declining - Selling exhaustion

Why the Handle Matters

The handle shakes out weak holders before the breakout. It's the final test before institutions push price higher. Without a handle, the pattern is less reliable.

Volume Confirmation

Volume Pattern

Cup Left Side: High volume (selling)
Cup Bottom: Low volume (accumulation)
Cup Right Side: Increasing volume (buying)
Handle: Declining volume (exhaustion)
Breakout: Surge 50%+ above average (confirmation)

Trading Strategy

Entry Rules

Cup depth 12-33%, duration 7-65 weeks, U-shaped
Handle forms in upper half, lasts 1-4 weeks
Volume declines during handle
Price breaks above handle high with volume surge
Enter on breakout candle close

Measured Move Target

Target = Breakout Price + Cup Depth ($)

Example: Breakout $100, Cup depth $20

Target = $100 + $20 = $120 (+20%)

Stop Loss

Conservative: Below handle low (7-8% risk)
Aggressive: Below breakout level (3-4% risk)

Common Mistakes

V-Shaped Cup: Sharp drops/recoveries fail more often. Need U-shape.
No Volume Surge: Breakout without volume = false breakout.
Deep Handle: Handle > 15% of cup depth = weakness.
Wrong Market: Pattern fails in bear markets. Need uptrend.
Impatience: Entering before breakout leads to whipsaws.
