How the pattern unfolds
The setup
Stock A has a previous range high near 253. It opens sharply higher, gapping above that level on opening enthusiasm.
What triggers it
The gap fails to extend. Price prints an upper wick, struggles to hold above the prior range high, and fades back below it through the session.
What it means — and does not
Returning into the prior range after a gap-up is the exhaustion footprint. The mechanic is absorption of opening demand. It is descriptive, and on other days a gap can equally hold and continue.
- Price / index level
- Volume
- Previous range high · 253
A gap-up above 253 on day 5 fails to hold and fades back into the prior range.

What this does not establish
The exhaustion reading is invalidated if price closes back above the prior range high at 253 and holds it. The high of the trap session is conventionally treated as the invalidation level, and a stop-loss is anchored above it. A move through that high means the gap was continuation rather than exhaustion.
Confirmation checklist
4Did price hold above the prior range high, or fade back inside it?
Was there an upper wick and stalling near the open?
Did volume show absorption rather than continuation?
Remember: many gaps hold. This is one pattern, not a signal.
Common mistakes reading it
2Chasing the open of a gap-up without checking whether it holds above the prior range.
Treating every gap-up as exhaustion. Plenty extend their move.
A gap up is fully filled by the close and price finishes inside the prior range. What was absorbed?
- The opening demand — the buying the gap itself represented was met by sellers all session
- The overnight news behind the gap
- The prior session's volume
Show the answer
A. The opening demand — the buying the gap itself represented was met by sellers all session
The gap is opening demand, priced in before the session starts. Returning into the range means that demand was met by supply across the day rather than followed by more buying. News does not get absorbed. Order flow does.
Frequently asked
3Does a gap-up always reverse?
No. Many gap-ups hold and continue. Exhaustion is the specific case where the gap fails and fades back into the range.
What hints that a gap may be exhausting?
Educationally, watchers look at whether price holds above the prior range. They also look for an upper wick, and for absorption on volume. None of this is a guarantee.
Is this telling me to sell?
No. LearnNifty explains the mechanic for learning and gives no trade instructions.
