Absorption: effort without result

The strongest story order flow can tell looks boring: aggression rises and price stands still. It means somebody on the other side is calmly taking the entire push.

There are always two roles in a market: the one who hits resting orders and the one who places them. Attention usually goes to the first — they move price and are visible on the chart. Absorption is the situation where the second turns out stronger: aggressive orders keep coming and price does not move, because standing in the way is someone willing to supply as much as is asked for.

What absorption looks like

Bearish: aggressive buying grows, price does not. Someone is selling buyers everything they take.
Bullish: aggressive selling grows, price does not fall. Someone is buying everything thrown at them.
In both cases the key sign is the same — large effort with zero progress.

sign = |delta| is large AND |price change| ≈ 0

Both conditions are required and are checked on the same window. Large delta with a large price move is ordinary strong flow, nothing special. Small delta with flat price is simply a lull. Only the gap between them is interesting.

Worked example

Worked through in numbers

A coin trades at 100,000. Over fifteen minutes: $40M of aggressive buying against $12M of selling — delta +$28M, a ratio above three to one. Price over those fifteen minutes: 100,000 → 100,050, that is five hundredths of a percent. For comparison, an ordinary day for this coin delivers one and a half percent on half that flow. Conclusion: the buyers met somebody for whom this price is acceptable for selling in any size. While that participant stands there, attempts to break the level will keep running into them.

Why this is practically valuable

Absorption is the rare case where order flow gives not a description but a testable claim about the near future: until the large passive participant is removed, price will not go up. The claim is easy to refute — if price leaves, they are gone, and you see it immediately. That is exactly what makes it good: it has a point at which it becomes clear you were wrong.

The link with a liquidity sweep

The most useful sequence looks like this: price moves beyond an obvious level (yesterday's low, equal lows) → aggressive selling rushes in → delta turns sharply negative → the fall stops → bids replenish → price returns back through the level. Here absorption explains WHY the sweep did not turn into a continued fall: whoever sold on the break was bought out in full.

Common mistake

'Price is not falling, so people are buying'

Not necessarily. Price may fail to fall simply because there is nobody left selling: the flow dried up. Delta tells the two apart. No selling and flat price — a lull, which can resolve either way. Heavy selling and flat price — somebody is there. Without flow these two states are indistinguishable on a chart, and that is the main value of delta.

What we show and what we deliberately do not

Everything needed to recognise absorption is here: delta over windows from a minute to an hour, price at the same moment, and a tape of large trades. We do not put an automatic 'absorption here' label and will not: the threshold for 'price barely moved' depends on the normal volatility of the specific coin, and an arbitrary threshold would become a pretty but wrong badge. The comparison is made by a person, and that is more honest.

Delta over four windows next to price, and a tape of large trades — on the coin page. Compare them yourself.

Exercise

Find three cases

Through the day, check coins from the most volatile list. Look for this state: fifteen-minute delta large in absolute terms while price over the same fifteen minutes barely changed. Find three such cases and write down what happened an hour later. Not for statistics — three cases prove nothing — but to train yourself to notice the state at all.

Check yourself

Delta over an hour is −$60M and price rose 0.8% over that hour. What is happening?
