A candle is a summary. The footprint is the receipt.
A five-minute candle tells you four numbers: open, high, low, close. Everything that actually happened in those five minutes — thousands of trades, at dozens of prices, with a specific shape — gets thrown away to draw one rectangle.
A footprint chart keeps it. Instead of a solid body, each candle is a stack of price levels, and at every level you see how much traded at the bid and how much traded at the ask.
01 — Reading one
The anatomy of a footprint candle
The most common display is bid × ask. Each row is one tick of price. The left number is volume that traded at the bid (aggressive selling). The right number is volume that traded at the ask (aggressive buying).
| Price | Bid × | Ask × | Delta | Note |
|---|---|---|---|---|
| 4514.50 | 88 | 41 | −47 | high of bar |
| 4514.25 | 210 | 96 | −114 | |
| 4514.00 | 402 | 388 | −14 | high volume node |
| 4513.75 | 156 | 301 | +145 | |
| 4513.50 | 64 | 340 | +276 | buy imbalance |
| 4513.25 | 71 | 118 | +47 | low of bar |
Total volume 2,275. Bar delta +293. But the number tells you far less than the shape: buyers were aggressive at the bottom of the bar, sellers took over at the top, and most of the business got done at 4514.00.
Look at what you can now see that a candle would hide entirely:
- Where the volume concentrated. 4514.00 traded 790 contracts — far more than any other level. That price is now meaningful.
- Where each side was aggressive. Buyers pushed from the low; sellers pushed at the high. That is a bar that ran out of buyers near the top.
- A lopsided level. At 4513.50 buyers outgunned sellers roughly five to one.
- A quiet top. Only 129 contracts traded at the high of the bar. There was very little interest up there.
02 — Display types
The three views you will meet
None is correct or incorrect. Most traders settle on bid × ask or delta for live reading, and use the profile view when they care about structure rather than participation.
03 — A workflow
What to actually look at, in order
The most common failure with footprint charts is staring at every number at once and drowning. Use an order of operations.
- Where is this bar on the chart? Location first, always. A footprint at yesterday's value area low means something. The same footprint in the middle of nowhere means nothing. If you have not marked your levels, the footprint cannot help you.
- Where did the volume concentrate? Find the heaviest level in the bar. That is where the auction spent its time and where both sides agreed to do business.
- Which side was aggressive, and where? Aggression at the extremes of a bar tells a different story from aggression in the middle.
- Did the aggression produce movement? The single most important question. Heavy buying at the top of a bar that then closed at the bottom is a completely different event from heavy buying that closed on the highs.
- Only then, the specific patterns. Imbalance, absorption, exhaustion. Those come next in the course and they only mean anything after the four questions above.
The core idea
The footprint does not generate signals. It answers questions you brought with you. If you arrive at the chart without a question — without a level, without a scenario — the footprint will happily show you thousands of numbers that mean nothing at all.
04 — Honest limits
What the footprint does not tell you
Limitations worth internalising
- It cannot show passive size that never got hit. A huge resting seller who only gets partially filled leaves a partial footprint. Much of the liquidity story stays hidden.
- It cannot tell you who. There is no way to distinguish a fund initiating a position from a market maker managing inventory from a retail trader panicking. The numbers look identical.
- It cannot tell you why. Heavy selling because of a headline you have not seen looks exactly like heavy selling for no reason. This gap is real and it is not solvable with more order flow data.
- Bar boundaries are arbitrary. The same activity split across two 5-minute bars versus contained in one produces very different-looking footprints. Be careful reading too much into a single bar's shape.
Common mistake
Zooming into the footprint and trading patterns inside individual bars, with no reference to higher timeframe structure.
This is the single most reliable way to lose money with order flow. The footprint is a microscope. Microscopes are useless for deciding where to point them — that is what structure and levels are for. Order flow refines a decision; it does not originate one.
05 — Putting it together
A practical example
NQ sells off into a level you marked before the session — the prior day's value area low.
- The bar that reaches the level shows heavy aggressive selling at its lower levels: 900+ contracts hitting bids across three ticks.
- Volume concentrates at the second-lowest tick, not at the low itself.
- The low of the bar trades only 80 contracts and is not revisited.
- The bar closes in its upper third.
Read the sequence: sellers pressed hard into a known level, the market found enough passive buying to hold, sellers could not extend, and price recovered off the low within the same bar.
That is a legitimate observation with a legitimate conclusion — sellers had their chance here and did not get paid. It is not yet a trade. It becomes one only with a plan for entry, invalidation and context, which is what the rest of the course builds toward.
Key takeaways
- A footprint chart opens each candle and shows bid and ask volume at every individual price.
- Read it in order: location → volume concentration → who was aggressive → did it produce movement.
- The heaviest-volume level inside a bar is where the auction did business, and it often matters later.
- The footprint cannot show unfilled passive size, participant identity, or reasons. Those limits are permanent.
- It is a microscope, not a map. Without levels and structure to point it at, it produces noise.
