Runaway Gap
A Runaway Gap — also called a continuation or measuring gap — is a price gap that occurs in the middle of an established trend. Unlike breakaway gaps that begin trends, runaway gaps confirm that the trend is healthy and likely to continue. Indian momentum traders use these gaps to add to winning positions and to estimate where the trend may extend to.
Key takeaways:
- Runaway gaps occur mid-trend and confirm trend continuation.
- Typically accompanied by strong volume and trend momentum.
- Used to estimate the full length of the move (roughly the midpoint).
- Less likely to be filled than common gaps.
- Best traded in the direction of the existing trend.
Where Runaway Gaps fit
After a breakaway gap and the initial trend leg, prices often pause briefly before another sharp move. The follow-up gap is the runaway gap — a sign that fresh participants are entering at higher (or lower) prices, accelerating the trend. They typically appear about halfway through the entire move, hence the alternate name “measuring gap”.
Using the gap to estimate targets
If the trend has moved X from the breakaway gap to the runaway gap, the move from the runaway gap often extends another X before exhaustion. This “measuring” property makes the gap useful for setting realistic targets and exit plans.
Volume and momentum context
Healthy runaway gaps are accompanied by:
- High relative volume on the gap day.
- Continued strong momentum after the gap.
- Broader market support — sector strength, positive breadth.
- No immediate fill — the gap stays open for several sessions.
How to trade Runaway Gaps
- Confirm the existing trend is strong (ADX > 25, rising moving averages).
- Identify the gap on a high-momentum day.
- Enter on a small pullback after the gap, or on a continuation breakout from the gap day’s high (or low for shorts).
- Project the target using the measuring rule.
- Place a stop just inside the gap or below the recent swing low.
Runaway gap vs breakaway gap
| Breakaway Gap | Runaway Gap | |
|---|---|---|
| Position in trend | Start of a new trend | Middle of an existing trend |
| Volume | Very high | High |
| Likelihood of fill | Low | Low |
| Use | Confirms breakout | Confirms trend strength; helps estimate targets |
Risks
Beware late-stage runaway gaps that look like exhaustion gaps. As the trend extends, gaps near major resistance or after extreme moves are more likely to be reversal signals. Combine with momentum indicators and trend strength tools to avoid mistaking exhaustion for continuation.
Frequently asked questions
Does a runaway gap need to be filled?
Usually not. Filling typically signals the end of the trend, not normal behaviour.
Can a runaway gap appear in downtrends?
Yes — they appear in both uptrends and downtrends with the same characteristics.
How can I tell it apart from an exhaustion gap?
Volume context and trend strength. Exhaustion gaps often appear at extreme levels with momentum divergence.
Best time frame to use?
Daily charts for swing trades; weekly for positional moves.
