Candlesticks keep four prices per period, the open, high, low and close, and discard everything in between. A footprint chart opens the same period up and shows the volume traded at each price, split by whether buyers or sellers crossed the spread, so it reports how the bar was built rather than only how it ended.
A daily candlestick is four prices. A footprint chart refuses that compression and shows, price by price, how much traded and which side crossed the spread to do it. We do not have that second kind of data, but SPY’s five-minute bars show how much a single daily candle leaves out.
What each one is
A candlestick reports the open, high, low and close of its period. Everything that happened between those four prices is dropped. Candlesticks covers what the body and wicks mean.
A footprint chart reports, for every price inside the bar, how much changed hands there, usually split into trades that hit the bid and trades that lifted the offer. Footprint chart covers the cells, delta and imbalances.
Both describe the same bar, at different resolutions. The footprint is not a different market; it is the candle with its contents still inside.
Where they differ
What survives. A candle keeps four prices, while a footprint keeps every traded price and the volume at each one, so it holds far more than the candle does.
Whether the order of events survives. A candle cannot say whether the high or the low came first. The footprint’s cells do not say it directly either, but the time-stamped trades behind them do.
Whether aggression is visible. Neither the candle nor its five-minute bars can show it. Only the footprint separates buyers who paid the offer from sellers who hit the bid. That split is an inference from the trade feed, and it is the footprint’s main reason to exist.
What each one needs. Candles come with any price feed, whereas a real footprint needs tick-level trades with side classification, which on most markets is a paid feed.
What a daily candle leaves out on SPY
The order of the extremes. Across 60 SPY sessions from July to October 2026, the day’s high printed before its low on 31 days and after it on 29, with no day where both fell in the same five-minute bar. A candle draws all 60 the same way, wick above and wick below, with no clue to the sequence.
Where the trading happened. Taking each five-minute bar’s close as its price, a median 50.39% of the day’s volume traded on bars that closed outside the candle’s open-to-close body, in the area the wicks cover. On 30 of the 60 days it was more than half. By range, 11 sessions were under 25%, 19 from 25% to 49.99%, 17 from 50% to 74.99% and 13 at 75% or more.
How far it ranged. On 17 August 2026 none of the volume traded on bars closing outside the body; on 1 October it was 90.33%. Two candles can look alike and still have been built in opposite ways, rather than in one.
Which one to use: Candlesticks or Footprint Charts?
Use candlesticks when your rules use the bar’s outcome. Closes, ranges, highs and lows are all the candle keeps, and they are all most methods need.
Use a footprint when your rule depends on who was aggressive at a price. Absorption, imbalances and delta exist only in that data, and no candle can be turned into it.
Use a footprint only when the feed is real. A footprint built from a feed without true trade sides is a guess drawn in fine detail.
And when you cannot afford the feed, use intraday candles for the part you can see. Five-minute bars already show the order of the high and low and roughly where the volume sat, as on this page.
Inside one doji: SPY, 1 October 2026
The candle. On 1 October 2026 SPY’s first five-minute bar opened at $764.36 and its last closed at $764.02, a body of 34 cents. The high was $765.65 at 15:50 and the low $758.79 at 11:10: a doji with a long lower wick.
What the five-minute bars add. 53 of the 78 bars closed below the body, and they carried 62.79% of the day’s volume; 20 closed above it, with 27.53%. Altogether 90.33% of the volume traded on bars that closed outside the body. The low came first and the high came last.
What only a footprint would add. Whether the heavy trading down near the low was sellers hitting bids or buyers lifting offers. Five-minute bars cannot say; that is the part that needs trade-side data.
The original data
The sample. Sixty complete SPY sessions of five-minute bars from Yahoo Finance, 10 July to 2 October 2026, each with 78 bars of regular hours. The daily candle here is built from those bars: the first open, the last close, and the highest high and lowest low. Sixty sessions is a small sample.
What was measured. The time of the first five-minute bar touching the day’s high and the day’s low; and the share of the day’s five-minute volume on bars whose close sat above the body’s top or below its bottom. That is volume by five-minute close, not by traded price, and it has no buyer or seller split, so it is a coarse view of what a footprint shows, not a footprint. Nothing on this page measures bid and ask, trade counts, volume at each price or delta; the site has no such data.
The file. Every session with its open, close, high and low, their times, and the outside-the-body volume share is in the SPY inside-the-candle file.
When it fails
The failure is reading a story into a candle’s shape that the bars inside contradict. A doji with a long lower wick is read as buyers rejecting the low, so it is bought. Inside it, as on 1 October, most of the day’s volume may have traded down in that wick, and without trade sides nobody can say whether that was buying or selling. The shape was taken for evidence of who won, when the candle never contained that information.
The second failure is paying for a footprint with no rule that uses it. More detail adds more to misread.
A third is trusting a footprint built from a feed without real trade sides. The split is then invented.
A fourth is generalizing from a few sessions. Sixty days is one season of one instrument.
And a fifth is assuming the high came first. On SPY it was close to even.

Candlesticks covers the four prices a bar keeps. Footprint chart covers the cells, delta and the data it needs. And price action covers reading the bars that both charts are built from.
Ask what you would do differently if you knew where inside the candle the volume traded. If the answer is nothing, the footprint is detail you will pay for and not use.
