Gap Trading for Swing Traders

A occurs when a stock opens well above or below its previous close, creating a visible "gap" on the chart. For swing traders holding overnight, gaps are both a risk to manage and an opportunity to trade.

Gap Types

Identifying Gap Type in Real-Time

The biggest challenge is distinguishing gap types as they happen. Key differentiators: where the gap occurs (in a range vs at a breakout), volume behavior afterward (continues or dries up), and whether the gap fills within a few days.

Gap Fill Probabilities

Common: 80-90% fill probability, 1-5 days
Breakaway: 20-30% fill probability, often never (becomes support)
Runaway: 40-50% fill probability, weeks to months if ever
Exhaustion: 90%+ fill probability, 1-5 days

Two Core Gap Strategies

Gap and Go Entry

When to Fade vs When NOT to Fade

Earnings Gap Caution

Fading earnings gaps carries high risk. Earnings gaps represent new fundamental information. Even when the reaction seems overdone, the stock often continues in the gap direction as analysts adjust models. Use minimal position sizes if you trade these.

Post-Earnings Gap Patterns

Rather than trading the gap itself, wait for the pattern that develops over the following 3-5 days:

Managing Gap Risk on Open Positions

Key Takeaways

Four gap types: common (fills 80-90%), breakaway (rarely fills), runaway (continuation), exhaustion (fills 90%+)
Gap and Go trades in the gap direction on high-volume breakaway gaps
Gap and Fade trades against low-significance common gaps. Do not fade earnings gaps.
Post-earnings patterns (pullbacks, flags) often offer better risk-reward than the gap itself
Manage gap risk through position sizing, diversification, and earnings calendar awareness

Look at a stock that recently had an earnings gap. Classify the gap type based on volume, location, and fill behavior. Did the gap fill within 5 days? If it was a breakaway gap, did a post-earnings flag or pullback pattern develop? What would have been the best trading strategy?
