Sierra Chart Footprint Charts — The Complete Guide for Order Flow Traders

If you trade futures and you have not yet learned to read a footprint chart, you are looking at half the picture. Price tells you where the market went. The footprint tells you how it got there — who was buying, who was selling, who got run over, and who walked away.

Sierra Chart ships a native footprint implementation called Numbers Bars. It is one of the most configurable footprints in the retail space, and once you understand how to read it, it becomes the foundation of an order-flow setup that no line chart can match.

This guide walks you through what a footprint is, how Numbers Bars implements it, the five classic patterns every order-flow trader should learn first, how to tune the chart so the signal is actually visible, where SCS studies layer on top, and the common mistakes that keep beginners stuck.

TL;DR — A footprint chart shows traded volume at every price inside every bar, split by buyers and sellers. Sierra Chart's native Numbers Bars is the chart type that draws it. Learn five patterns first — absorption, exhaustion, P-shape, b-shape, finished auction — and tune your cell display to your screen size before adding anything else. Sierra Chart's native footprint is excellent on its own. SCS studies do not replace it; they layer specific signals on top, like Delta Candle Color for overlay context and Single Print and Gap for persistent zone detection.

What a footprint chart actually is

A standard candlestick aggregates a bar's activity into four numbers: open, high, low, close. That throws away the most useful part of the data — the distribution of volume inside the bar.

A footprint chart keeps it. Every bar becomes a vertical stack of price levels (one per tick, or one per N ticks if you group them), and each price level shows two numbers: how much was bought at the ask, and how much was sold at the bid. The two together — bid/ask volume split — is what makes the chart a footprint.

From those two numbers you can derive everything an order-flow trader cares about inside a single bar:

• Volume per price — where the activity actually clustered, not just the high-low range
• Delta per price — buyers minus sellers at each level, where the imbalance lives
• Cumulative delta — the running tally as the bar prints
• Point of control — the price level with the most volume in the bar (intra-bar POC)
• Imbalances — levels where one side dominates the other by a configurable ratio

A candlestick gives you four numbers per bar. A footprint gives you fifty to several hundred, depending on the bar's range. That is the trade-off: more signal, more noise, steeper learning curve, but a fundamentally different read on what the market is doing.

How Sierra Chart implements footprint via Numbers Bars

In Sierra Chart, the footprint is not a study — it is a chart type. You change the chart from Candlestick to Numbers Bars (right-click chart → Chart Settings → Graph Type → Numbers Bars), and the platform redraws every bar as a footprint.

The implementation is dense. Numbers Bars exposes a long list of options for what to display inside each cell — bid volume, ask volume, delta, volume, percentage of bar volume, intra-bar POC, imbalance highlighting, value area, and several display layouts (side-by-side, single column, profile-style). It is not unusual to spend an hour on first setup tuning the cells to a layout you can actually read at a glance.

The data underneath Numbers Bars is the same tick-by-tick bid/ask data Sierra Chart records to the SCID file. That means the footprint is reconstructable historically — you can scroll back days, weeks, or months and the cells are still populated as long as you have the recorded data. This is one of Sierra Chart's quiet strengths versus platforms that only render footprints in real time.

A few practical notes before you start configuring:

• Bar interval matters. A 1-minute Numbers Bars chart on ES during the New York open generates 50+ price levels per bar — unreadable on most screens. Most footprint traders use range bars, tick bars (e.g. 1000 tick), or volume bars (e.g. 2500 contract) to get bars sized for the instrument's volatility rather than the wall clock.
• Cell font matters. Numbers Bars displays text in every cell. Pick a font size that lets you read the numbers without leaning forward. If you can't read the cells, you can't read the chart.
• Imbalance highlighting matters. Numbers Bars can highlight cells where bid or ask volume dominates by a configurable ratio (commonly 3× or 4×). Turn this on. Stacked imbalances are one of the highest-information signals on the chart.

The five footprint patterns to learn first

A working footprint vocabulary is small. Five patterns will get you 80% of the way to reading the chart fluently.

1. Absorption

Absorption is when heavy volume hits one side of the book but price does not move. You see large ask volume (aggressive buying) printing in a cell at the highs — and the next bars trade at or below the same level. The buyers spent the inventory; the sellers absorbed it without flinching. This often precedes a reversal because the directional pressure has been quietly bled out without yielding new highs.

The footprint signature: a sequence of cells with high one-sided volume, low or negative delta net effect, and price that fails to extend.

2. Exhaustion

Exhaustion is the opposite of absorption in mood but related in mechanics. After an extended directional move, you see a final bar with a delta spike in the trend direction — strong ask volume on the up move, or strong bid volume on the down move — followed by an immediate reversal on lighter volume. The aggressive traders pushed the last lot of inventory; nobody is left to follow them.

The footprint signature: a delta extreme at the swing high/low followed by a bar with delta flipping sign on the next print.

3. P-shape (long liquidation)

A P-shape forms inside a bar (or across a small cluster of bars) when volume builds up on the upper half and then trails off below — the bar's volume profile looks like the letter P rotated. It typically marks long liquidation: buyers got in higher, the move stalled, and they started exiting back into a thinner book underneath.

When you see this at a swing high after a rally, it is a heads-up that the upside auction has finished and the market may rotate down to fill the lighter activity below.

4. b-shape (short covering)

The mirror image. Volume builds up on the lower half of a bar (or cluster), then thins above — the profile looks like a lowercase b. This typically marks short covering: shorts got in lower, the move stalled, and they started covering up into a thinner book above.

At a swing low after a decline, this is the same heads-up in reverse — the downside auction is finishing, rotation up to fill is on the table.

5. Finished auction

A finished auction is the cleanest reversal pattern on a footprint. The last bar of the move shows balanced volume distribution all the way to its extreme, with no extension in the next bar — no single print, no continuation. The market said we've offered up here and nobody is taking it. Combined with absorption at the same level, this is one of the higher-conviction reversal reads on the chart.

The footprint signature: even bid/ask distribution top to bottom of a bar at the swing extreme, next bar fails to break the level, delta neutral or against the prior direction.

Tuning Numbers Bars so you can actually read it

A poorly tuned Numbers Bars chart is unusable. A well-tuned one becomes your default chart type. The difference is mostly in three settings:

Cell content. Don't display everything. Start with bid × ask side-by-side per cell, add delta if it helps you, hide volume-per-cell unless you need it. The cell is small — every extra number competes for the same space.

Imbalance highlighting. Set the imbalance ratio (commonly 3× or 4×) and pick high-contrast colors for the highlighted cells. The whole point of imbalance highlighting is that your eye picks up stacked imbalances at a glance — make sure the colors do that.

Bar sizing. Use range bars or tick bars sized for the instrument's typical bar volume. A useful starting point: a bar size where the average bar has 10–25 price levels of activity. Smaller and the footprint is too sparse to read; larger and the cells are too small.

Bid/ask split layout. Numbers Bars supports several layouts — side by side, stacked, single-column delta. Pick one and stick with it for at least a week before judging. The pattern recognition only builds in once your eye knows where each number lives.

Where SCS studies layer on top of native footprint

This is where to be honest: Sierra Chart's native Numbers Bars covers the core footprint surface very well. You do not need an extra study to have a footprint. SCS studies do not replace Numbers Bars — they add specific signals that are awkward to extract from the raw cells.

Delta Candle Color recolors each candle based on delta momentum relative to price. On a Numbers Bars chart, you read the per-bar delta in the cells; with Delta Candle Color, you also see at full chart zoom which bars showed initiative buying versus initiative selling versus absorption (delta against price). It is the same intent as imbalance highlighting, but rolled up to the bar level and visible without leaning into individual cells. Useful when you are zoomed out and want context before zooming in.

Single Print and Gap detects single-tick zones inside the session — levels where the market moved through with one-sided activity and left a structural gap — and draws them as persistent zones on the chart, including partial fill behavior as price walks back through. Numbers Bars shows you single prints in the cells when you scroll to the original bar. Single Print and Gap surfaces them as persistent reference levels for the rest of the session.

Neither study is a footprint replacement. They are footprint augmentations for two specific use cases — overlay context and persistent zone tracking — that the native cells handle but do not surface ergonomically.

Common footprint mistakes to avoid

A few traps that catch most footprint beginners:

• Reading single bars in isolation. Footprint patterns matter in context. A delta spike at the end of a multi-day rally means something different than the same delta spike inside chop. Always read the bar within the trend and the session.
• Trusting delta absolutism. Positive delta does not mean price will go up. Positive delta combined with no upside progression (absorption) often means the opposite. Direction-of-trade tells you nothing without price reaction.
• Mistaking auction completion for reversal. A finished auction means the local move has used up its fuel. It does not mean price reverses immediately. Sometimes the market rotates, sometimes it consolidates, sometimes a fresh impulse arrives ten minutes later. The footprint signals exhaustion of inventory, not guaranteed reversal.
• Configuring the chart and never re-tuning it. Markets change volatility regimes. The cell layout and bar size that worked on ES in low volatility may be unreadable in high volatility. Re-tune when the chart stops being readable.
• Trying to footprint everything. Footprint is high-information on instruments with deep transparent order flow (ES, NQ, CL, GC, ZN). On thin instruments, the cells are too sparse to read patterns reliably. Pick your footprint instruments deliberately.

Frequently asked

Do I need a special data feed for footprint? You need a feed that provides bid/ask trade classification at the tick level. Most professional futures feeds (Denali, Rithmic, CQG via Sierra Chart) provide this. If your feed gives you tick volume but no bid/ask split, the footprint cells will be missing the most important number.

Is footprint useful on stocks? Less so than on futures, for two reasons: stock liquidity is fragmented across many venues so the bid/ask classification is noisier, and the most useful footprint setups assume a single deep book. Most footprint traders focus on liquid futures.

Can I run footprint and a regular candlestick chart in the same chartbook? Yes. Many traders run a Numbers Bars chart for the close-in read and a higher-timeframe candlestick chart for context. They share the same data, so there is no extra cost.

Do I need both Numbers Bars and SCS studies? Numbers Bars first. If after a few weeks of reading the cells fluently you find yourself missing context at chart-wide zoom (Delta Candle Color) or wanting persistent zone tracking (Single Print and Gap), then add the studies. Don't buy them before you can read the native cells.

How long does it take to learn to read footprint? Realistically, several weeks of daily screen time before patterns start jumping out. The cells look like noise at first. Stick with one instrument, one bar type, one cell layout — fluency comes from repetition.

Get started

If you trade futures and you want to add a real order-flow read to your setup, start with Numbers Bars on one instrument you already trade. Spend a week reading the cells with nothing else loaded. Then, if you want overlay context at chart-wide zoom or persistent zone tracking, look at Delta Candle Color and Single Print and Gap — both layer cleanly on top of a Numbers Bars chart without competing with the native cells.

The full SCS catalog of Sierra Chart custom studies covers the rest of the order-flow surface — CVD, depth tooling, zero-print zones, execution layer. Every study ships with a 7-day satisfaction guarantee so you can test it on your real chart before committing.
