Absorption Recognition and Reversal Signals

Absorption is the moment aggressive market orders hit a wall of resting limit orders and price stops moving. The aggressive side spends its ammunition; the passive side soaks it up. Absorption at an extreme is one of the cleanest reversal precursors in order flow.

The signature: delta divergence

Delta is net aggressive volume (market buys minus market sells). In a normal move, delta and price move together — price up, delta positive. Absorption breaks this:

• Bearish absorption (reversal up): price prints a new low, but delta is positive or flat. Aggressive sellers hit bids, yet price won't fall — buyers absorbed the sells.
• Bullish absorption (reversal down): price prints a new high, but delta is negative or flat. Aggressive buyers lift offers, yet price won't rise — sellers absorbed the buys.

The footprint shows the same story: heavy volume at the extreme price with the opposite-side delta dominant.

How to confirm absorption

Three confirmations, in order:

1. High total volume at the extreme (≥2× the session average per price).
2. Delta divergence — delta opposite to the price move at the extreme.
3. Price stall — 3+ candles fail to extend the extreme despite continued aggression.

Trading the absorption reversal

Long (bearish absorption at support)

1. Price tests a known support level (prior HVN, daily S1).
2. Heavy selling volume prints, delta stays flat or positive, price stalls.
3. Enter long on the first candle that closes above the absorption candle's high.
4. Stop: 1 tick below the absorption low. Target: the session POC or prior swing high (minimum 2:1 R:R).

Short (bullish absorption at resistance)

1. Price tests resistance.
2. Heavy buying volume, delta flat or negative, price stalls.
3. Enter short on the first close below the absorption candle's low.
4. Stop: 1 tick above the absorption high. Target: session POC or prior swing low.

Absorption failure

Absorption is not a guarantee. It fails when:

• The absorbing side is exhausted and a second wave of aggression breaks the level. If price closes 2 ticks beyond the absorption extreme, the level failed — exit and reverse.
• The move is part of a strong trend. Absorption against a clear higher-timeframe trend often gets overrun. Only trade absorption aligned with the HTF trend.

Absorption vs exhaustion

Do not confuse them. Exhaustion is the aggressive side running out of fuel (volume fades, no new extreme). Absorption is the aggressive side being soaked up (volume stays high, price stalls). Exhaustion warns; absorption acts. The reversal entry fires on absorption confirmation — high volume, delta divergence, price stall — at a structural level.
