đĄ What is a Market Gap?
A market gap occurs when an asset’s price opens significantly higher or lower than its previous close, creating a “gap” on the price chart. These typically happen when:
- Major news breaks after hours
- Earnings reports surprise investors
- Economic data shocks the market
- Overnight sentiment shifts dramatically
đ Key Characteristics:
- Shows as a blank space on candlestick/bar charts
- Represents instant repricing by the market
- Occurs across all markets (stocks, forex, crypto)
Why Gaps Matter:
â Reveal powerful shifts in supply/demand
â Create risk/reward opportunities
â Show where liquidity is lacking
â Often act as future support/resistance
đ§Š The 4 Types of Market Gaps (With Examples)
1ď¸âŁ Common Gaps

- Small, frequent gaps in quiet markets
- Usually fill quickly (price returns to pre-gap levels)
- Example: A stock gapping $0.10 on low volume
2ď¸âŁ Breakaway Gaps

- Signal start of new trends
- Occur after consolidation patterns
- Example: Bitcoin breaking $20,000 in 2020
3ď¸âŁ Runaway (Measuring) Gaps

- Mid-trend acceleration
- Indicate strong continuation
- Example: Tesla during 2020 rally
4ď¸âŁ Exhaustion Gaps

- Final push before reversals
- Often see massive volume
- Example: GameStop January 2021 peak
đĄ Pro Tip: I keep a screenshot album of textbook gaps – it’s helped me recognize patterns faster.
đ How to Identify & Trade Gaps
The Gap Filling Strategy (For Common Gaps)

đ Reading the Gap Tea Leaves
Gap Type | Volume | Likelihood to Fill | Trading Approach |
---|---|---|---|
Common | Low | High | Fade the gap |
Breakaway | High | Low | Follow momentum |
Runaway | Medium | 50/50 | Trend continuation |
Exhaustion | Very High | High likelihood to fill, but timing can vary | Prepare to reverse |
“My biggest win came from recognizing a breakaway gap in NVIDIA before its AI boom – the gap never filled and became launchpad for 300% gains.”
