Once you can read footprint cells, the next question is *what to look for*. There are only a handful of footprint patterns that actually earn their keep, and each one is a specific signature of how aggression met liquidity at a price. This is the catalog: what each pattern looks like, what it means, and where to go for the full mechanics.

Think of this page as the index. If you have not read a footprint before, start with the [footprint chart guide](/en/footprint-chart/) and the [bid x ask](/en/bid-ask-footprint/) display; everything below assumes you can already read the numbers.

## Imbalances

An imbalance is aggression that got its way: one diagonal side of a price hugely outweighs the other, typically by a **300% ratio** or more. A buy imbalance means aggressive buying (ask volume) overwhelmed the aggressive selling one tick below; a sell imbalance is the reverse. It marks where one side committed hard enough to move price.

Single imbalances are data points. The full read, why they are measured on the diagonal, how to filter noise, lives in [order flow imbalances](/en/order-flow-imbalances/).

## Stacked imbalances

When three or more imbalances line up on consecutive rows in the same direction, you get a *zone*, not a point. Stacked buy imbalances mark a price band aggressive buyers defended in size, and that band tends to act as support on a retest; stacked sell imbalances cap price as resistance. They are among the most reliable footprint signatures for marking levels.

The way to trade the retest of these zones is covered in [stacked imbalances](/en/stacked-imbalances/).

## Absorption

Absorption is the mirror image of an imbalance: aggression that *failed*. Huge aggressive volume hits one side, but price barely moves and then reverses. At a low, heavy selling at the bid that cannot push price down means a passive buyer is soaking up every seller, the sellers are spent and the buyer is in control. The tell is the mismatch: big effort, tiny result.

The full signature and how to trade it is in [absorption trading](/en/absorption-trading/), and the closely related question of when heavy aggression is absorption versus a seller simply running out of steam is in [absorption vs exhaustion](/en/absorption-vs-exhaustion/).

## Unfinished auctions

At a swing high or low, the extreme row "finishes" when it trades on both sides, buyers and sellers both transact at the turn before price reverses. When the very top row shows only buying at the ask with nothing selling above (or only selling at a low), the auction is *unfinished*: price left before fully rejecting the level. Those unfinished highs and lows act as magnets and tend to get revisited.

The mechanics and how to use them as target levels are in [unfinished auctions](/en/unfinished-auction/).

## Big prints

A big print is a single cell carrying unusually large volume relative to everything around it, a slug of size that hit one price at once. It flags where a large participant showed up. What it *means* depends entirely on context: a big print at an extreme that stalls price is absorption; the same print mid-move with price continuing is a drive.

How to read them, and how to tell a meaningful big print from routine heavy volume, is in [big prints](/en/big-prints-footprint/).

## Delta divergence inside the bar

Watch the net aggression against price direction. A green candle that closes near its high but carries negative delta means sellers were aggressive the whole way up while a passive buyer absorbed them, that is often stronger than a green candle with matching positive delta. A new price high with weak or falling delta at the top warns the move is not backed by aggression.

The intrabar version shows on the [delta footprint](/en/delta-footprint/); the full divergence read, confirmed across bars on cumulative delta, is in [delta divergence](/en/delta-divergence/) and the broader [cumulative delta guide](/en/cumulative-delta/).

## Point of control shifts

The intrabar POC is the heaviest row of a bar. Track how it migrates from bar to bar. A POC that climbs steadily with real volume behind it shows an auction accepting higher prices; a POC that stalls while price grinds higher warns the up-move is thinning out. It is a slower, structural pattern rather than a single-bar signal, and it pairs naturally with a session [volume profile](/en/volume-profile/) for context.

## How to actually use these

A quick way to keep the catalog straight:

| Pattern | One-line meaning | Reads as |
|---------|------------------|----------|
| Imbalance | Aggression that got its way | Directional commitment |
| Stacked imbalances | A committed *zone* | Support / resistance |
| Absorption | Aggression that failed | Reversal fuel |
| Unfinished auction | Level left un-rejected | Magnet / target |
| Big print | Large size at one price | Context-dependent |
| Delta divergence | Aggression disagrees with price | Warning |
| POC shift | Where trade concentrates, bar to bar | Acceptance / rejection |

Two rules make the difference between a pattern-spotter and a trader. First, **never trade a pattern in a vacuum.** A stacked imbalance mid-range is noise; the same one at a session VAL, confirmed by [cumulative delta](/en/cumulative-delta/), is a setup. Second, **patterns confirm, they do not predict.** They tell you what aggression just did at a level, which is powerful precisely because it is real, not a projection.

Get comfortable spotting these six or seven signatures and you have most of what the footprint offers. The way they combine with delta, volume profile and VWAP into a complete read is laid out in the [order flow trading guide](/en/order-flow-trading/).

## Frequently Asked Questions

### What are the most important footprint chart patterns?

The ones that earn their keep are imbalances, stacked imbalances, absorption, unfinished auctions, big prints, delta divergence, and point-of-control shifts. Each is a specific signature of how aggressive orders met resting liquidity at a price. You do not need dozens of patterns, these few carry most of the weight.

### What is the difference between an imbalance and absorption?

An imbalance is aggression that got its way, one side overwhelmed the other and price moved. Absorption is aggression that failed, heavy volume hit one side but a passive player soaked it up and price did not move. Same raw footprint data, opposite outcome, so context tells you which you are looking at.

### Do footprint patterns work on their own?

No. A pattern in the middle of a range is usually noise. The same pattern at a level that already matters, a session extreme, a value area edge, a prior POC, and confirmed by delta, is a setup. Footprint patterns confirm what aggression is doing at a level; they are not standalone predictions.

### Which footprint pattern is most reliable for support and resistance?

Stacked imbalances, three or more imbalances on consecutive rows in the same direction, mark a price band that aggressive traders defended in size, and that band tends to hold on a retest. They are strongest when they line up with volume profile structure like a value area edge or a high volume node.
