Footprint Candle
An advanced candle type that displays the volume transacted at each price level within the bar — showing the bid×ask split that a standard candle hides.
A Footprint Candle (also called a Footprint Chart or Cluster Chart) breaks open a standard candlestick to show the volume traded at every individual price level — and, critically, how much was traded on the bid (sells) versus the ask (buys).
Anatomy of a Footprint Candle:
- ●Each price level inside the bar shows two numbers: volume hitting the bid (left) and volume lifting the ask (right).
- ●The difference between ask-volume and bid-volume at a level is the Delta at that price.
- ●Consecutive levels where one side dominates by a fixed ratio (e.g. 3:1) flag a Stacked Imbalance — an institutional footprint.
- ●The level with the highest total volume is the Point of Control (POC) — the price the market "accepted" most during that candle.
Who uses them: primarily futures and equity traders on platforms like Sierra Chart, Bookmap, or MotiveWave, using CME data (ES, NQ). Footprint Charts are the gold standard for reading intraday Order Flow.
The SPX problem: SPX options do not trade on a centralized exchange with a single, complete trade tape. CBOE execution data is fragmented and the bid×ask fill-level detail that a Footprint Candle requires is either unavailable or prohibitively delayed for retail accounts. You cannot pull up a standard Footprint Candle on SPX the way you can on ES.
What SPXXL does instead: the engine proxies the same insights Footprint Candles reveal — momentum, Imbalance, Absorption, Delta Divergence — using the signals it CAN observe: options chain Gamma, VWAP deviation, relative volume, and compression/expansion ratios. The new "6-Step Order Flow Confirmation" widget on the dashboard maps each canonical Footprint concept to its closest SPXXL proxy, with an honesty note where the proxy is approximate.
For 0DTE traders: if you have studied Footprint Charts on ES or NQ, the logic transfers directly — SPXXL just translates it into the SPX regime where the raw tape is not available.
This entry is educational and uses SPX for illustration — it is not financial advice, and no outcome is predicted or guaranteed.
