Absorption in plain words
Absorption happens when big resting limit orders soak up a wave of aggressive market orders without letting price move much — a setup that can come before a pullback or a reversal.1
Picture heavy buying hitting a level where a large seller, often hiding size in an iceberg order, quietly fills every order; the reverse works for selling.2
Price stalls even though aggressive volume is high.
How to spot absorption
Mark a key level
Use prior Support and Resistance.
Watch aggressive volume
Track market orders hitting the level.
Check price response
Watch for trades printing again and again at one price while the price itself stays put.3
Watch the book
See whether displayed size refreshes (possible iceberg).
Wait for confirmation
Absorbed levels often become turning points, so wait for price to bounce and confirm the new direction.2
Define risk
Place a stop beyond the absorbing level.
Worked examples
Example 1 — Sell-side absorption
Possible topHypothetically, 5,000 contracts of market buys hit an offer at 100.50, yet price stays at 100.50.
| Aggressive buys | 5,000 |
| Price change | 0 |
Large resting sell limit orders absorb large buying aggressors — buyers may be exhausting.2
Example 2 — Bounce after absorption
Confirmed bounceSellers hit a hypothetical bid at 50.00; price then rallies to 50.40.
| Move | +0.40 |
The level held and price turned, which is the typical outcome when absorption is real.2
Example 3 — Absorption fails
Level brokeBuy absorption at a hypothetical 75.00 gives way and price drops to 74.60.
| Move | −0.40 |
Absorption only hints at a pullback or reversal — it is not a guarantee — so a stop just beyond the level caps the loss.1

|---|---|---|
| What happens | Passive orders soak up aggression | Aggressive orders dry up |

Mechanics
Beginner
The absorbing side uses limit orders, which trade only at a set price or better, while the aggressive side crosses the spread as the “taker” and usually pays a fee for it.4
Icebergs
Intermediate
Part of the absorbing size is often hidden in iceberg orders, so the order book can show far less than is really there.2
Spoofing caution
Advanced
Displayed size can be pulled at any moment, so focus on actual executions repeating at a level without price moving.3
Common mistakes
Trading displayed size alone
Look for actual executions.
No confirmation
Wait for price to move away.
Ignoring context
Use higher-timeframe levels.
No stop
Absorption can fail.
