Gap Patterns Trading Strategy: What Every Gap Type Tells You About Momentum
A stock closes at $150 on Friday. On Monday, it opens at $162. That $12 void on the chart is not an inconvenience — it is a signal. Gap patterns reveal sudden shifts in supply and demand, and knowing which type you are looking at determines whether you should buy the strength, fade the move, or wait for a fill.
The Four Types of Gaps
1. Breakaway Gap
Occurs when price gaps out of a consolidation pattern — a triangle, rectangle, or channel. The gap itself is the breakout.
- High volume on the gap day (2-3x normal)
- Price does not return to fill the gap short-term
- The gap becomes new support/resistance
- Trade it: Enter in the gap direction. Stop below the gap level. Target: the pattern's measured move.
NVDA gapping above a multi-week ascending triangle on strong earnings marked the beginning of a massive unfilled rally.
2. Runaway (Continuation) Gap
Occurs within an established trend, usually at the midpoint. Signals trend acceleration.
- Moderate to high volume
- Trend continues without hesitation
- Often appears in series during strong trends
- The midpoint rule: If a stock rallied $20 before the gap, expect approximately another $20 above the gap.
3. Exhaustion Gap
The trap. Looks like a breakaway gap but occurs at the END of a trend. Price reverses within days.
- Very high volume — often the highest of the entire trend
- Price reverses within 3-5 days and fills the gap
- Often accompanied by reversal candles (doji, shooting star)
- Key distinction: Exhaustion gaps fill quickly. Breakaway gaps do not.
4. Common Gap
Happens in normal trading with no pattern context. Small size, normal volume, fills quickly. Most traders ignore them.
Gap Fill Probabilities
- Common gaps: Fill within 5 days ~70-80% of the time
- Exhaustion gaps: Fill within 10 days ~80-90%
- Runaway gaps: Fill within 30 days ~50-60%
- Breakaway gaps: Many never fill; those that do take months
"Gaps always fill" is misleading because it ignores the when.
Combining Gaps With Chart Patterns
Gap breakout from a pattern: A breakaway gap out of a triangle or rectangle is the strongest breakout signal. The gap eliminates the common retest problem. TSLA frequently gaps out of consolidation patterns after earnings.
Gap into a pattern level: A stock gapping down to double bottom support or up to double top resistance tests the pattern's validity. If the level holds despite the gap, the pattern is confirmed with extra strength.
Gap after a breakout: A breakout followed by a gap in the same direction 1-2 days later is a powerful continuation signal.
Risk Management for Gap Trades
- Gap as a stop level: For breakaway gaps, place your stop at the gap level. A complete fill means the breakout failed.
- Reduce position size on gap days: The wider intraday range means larger dollar risk per share.
- Never chase an extended gap: If a stock gaps 8% and trades another 3% higher, you missed it. Wait for a pullback or move on.
