Footprint Chart
crypto — Complete guide
The Footprint Chart is the most precise orderflow tool available to crypto traders. Unlike classic Japanese candlesticks, it reveals the volume traded at each price level inside a candle — broken down between aggressive buyers (Ask) and aggressive sellers (Bid).
What is the Footprint Chart?
A classic Japanese candlestick tells you the open, high, low, and close. It tells you where the market went, but not how. The Footprint Chart fills this gap: it displays, for each price level inside the candle, how much volume was traded by aggressive buyers (Ask) and aggressive sellers (Bid).
This information comes from aggTrades — individual transactions — not from OHLCV. Each trade is classified: if it was executed at the Ask price (the buyer hit the lowest available ask), it counts on the Ask side. If at the Bid price (the seller hit the bid offer), it counts on the Bid side.
Footprint cell structure
The Footprint breaks each candle into a grid of cells. Each row corresponds to a tick or an aggregated price level. In each cell, you see:
- Ask volume (left or green) — Aggressive buyer volume at this price level
- Bid volume (right or red) — Aggressive seller volume at this price level
- Cell delta — Ask − Bid difference, visible in certain display modes
The height of each cell (the tick size) is adjustable depending on your instrument and zoom level. On Bitcoin, grouping by $10–50 increments is common on 5 or 15-minute candles.
Different display modes
Footprint Charts come in several variants: Volume Profile Footprint (horizontal volume bars), Delta Footprint (shows only Ask−Bid difference), Bid×Ask Footprint (most common, shows both columns). CrypView uses the Bid×Ask mode, the most informative for orderflow analysis.
Imbalance detection
An imbalance occurs when one side — Ask or Bid — massively dominates the other at a given price level. In CrypView, a cell is flagged as an imbalance when the ratio exceeds 3× in favour of one side.
Imbalances have particular significance: they indicate the market traversed this price level aggressively, without meaningful resistance from the other side. These zones often become important support/resistance levels on subsequent visits, as the market tends to return to "fill" the imbalance.
Bullish imbalances (Ask dominant)
When Ask volume is 3× or more than Bid volume at a price level, it's a bullish imbalance. Buyers crossed this level with force. If price returns to test this level later, buyers often defend their position — it's a potential support.
Bearish imbalances (Bid dominant)
The reverse: sellers dominated massively at this level. The market encountered strong selling pressure there. On a price return, it's a potential resistance to watch.
Point of Control (POC)
The Point of Control of a Footprint is the price level where total volume (Ask + Bid) is highest inside a candle. It's the "centre of gravity" of that candle — the level where the market spent the most time and traded the most volume.
A candle's POC has several practical uses:
- Equilibrium zone — The market frequently returns to it after extensions
- Entry reference — A return to the POC of a strong candle is often an entry opportunity in the candle's direction
- Trend filter — If price regularly closes above the POC, the trend is bullish
Reading a Footprint Chart
Reading a Footprint goes bottom to top for bullish candles, top to bottom for bearish ones — in the direction of price movement. Here's what to look for:
| Signal | What it indicates | Meaning |
|---|---|---|
| Ask dominant + bullish candle | Buyers active throughout the candle | Confirmed bullish |
| Bid dominant + bullish candle | Price rises but sellers resist | Divergence — Caution |
| Close below candle POC | Sellers regained control at candle close | Bullish weakness |
| Strong Ask imbalance at support | Sellers absorbed by buyers | Strong support |
Practical strategies with the Footprint
Support/resistance absorption
One of the most popular Footprint strategies is absorption detection. When price tests a support level and the Footprint shows strong Bid volume (sellers) but price doesn't fall — or bounces — it means buyers are absorbing all available supply. That's a strong bullish signal.
Move exhaustion
A bullish candle with strong Ask volume in the upper cells, combined with a candle close that returns to the middle of the candle, indicates buyer exhaustion. The market moved violently upward but sellers took back control before the close — potential reversal signal.
Footprint + Volume Profile confluence
Combine the Footprint with the Volume Profile to identify high-confluence zones: a Volume Profile POC coinciding with an unfilled Footprint imbalance zone is a price level to watch closely. Both methods mutually confirm each other.
