Absorption

Big passive orders soak up aggression — high volume, no movement.

Absorption

When large passive limit orders soak up aggressive market orders, so heavy volume executes at a level but price barely moves. Aggressive buyers keep lifting the offer, yet a bigger passive seller keeps refilling it — and price stalls.

The footprint signature is high total volume with little or no price progress — effort without result. Often the absorbing orders are icebergs: resting orders that show only a small size on the book while quietly refilling, which is why absorption can happen with no obvious resting liquidity visible on the DOM.

Bid — aggressive sellersAsk — aggressive buyersBuy imbalanceSell imbalancePOC (most volume)Candle = bar direction

Absorption at the high. Bar 2's 4503.25 level shows a massive 420 ask (aggressive buyers piling in), yet price fails to extend above 4503.50. ① All that buying is being absorbed by a passive seller. Bar 3 then reverses down — the trapped buyers fuel the move.

The tell is effort vs result. A huge positive delta or huge ask volume that fails to make a new high is the opposite of strength — a larger hidden player is on the other side. If aggressive sellers can't push price down because a big buyer absorbs them, hidden demand can force a turn up (and vice versa).

Absorption can fail: if the aggressors are ultimately bigger than the absorbing orders, price breaks through. That's exactly why a trade based on absorption places its stop just beyond the absorbing extreme — if price clears it, the thesis is wrong.

Key takeaways

Absorption = large passive orders soaking up aggression; high volume, little price movement.
Signature: heavy ask volume that fails to make a new high (or heavy bid volume that fails to make a new low).
Often driven by hidden iceberg orders, so the DOM may look thin.
It can precede reversals — but it can also fail, so stops go just beyond the absorbing extreme.

Question 1 of 2

Which footprint picture best describes absorption at a high?

Absorption is heavy aggression with no result: large ask (buying) volume at the high, but price can't extend — a bigger passive seller is filling it all.

Question 2 of 2

Where should a stop go on a long-reversal trade based on buyers being absorbed (i.e., you're shorting the absorbed high)? And why?

If price pushes through the level the absorbing orders were defending, the aggressors won and the thesis is wrong — so the stop sits just beyond that extreme, keeping risk tight and logical.
