Price tells you where the market went. The heatmap tells you what it had to get through: every resting limit order, coloured by size, scrolling left as time passes, with the aggressive prints that hit them drawn on top.
Each read is a stated rule rather than a threshold tuned by feel, so what fires is checkable. On Elite they are drawn on the chart where they happened, named in the flow panel beside it, and matched by your alert rules.
A print past a running mean plus k standard deviations, calibrated per instrument by Welford update, so large means large for that instrument, on BTC or a thin altcoin. A sweep takes four or more price rows on one side inside a single slice, and a liquidation is a position the exchange closed for its owner.
Absorption is sustained one sided aggression while the touch refuses to move. A refill is more volume traded at a price than was ever displayed there, which is an iceberg. And when a wall goes, the book and the prints between them say which way: eaten by the tape, or pulled before it was hit.
A stop run is a prior high or low broken on a burst that price then comes straight back through. A break that holds was a breakout, and nothing fires. A spoof candidate is a wall the market reached that vanished untraded. Both report the shape of an event, never anybody's intent.
The chart is a time by price grid. Each column is one sample of the whole book, each row is a band of price, and three more layers are drawn over the top of it.
Every limit order sitting in the book, summed into its price row and coloured against a rolling upper quantile of what is currently resting. Ordinary depth stays a dark field, so a wall reads as a bright horizontal bar and its disappearance is just as visible.
Every fill, placed at the price it happened and sized by value, green when the buyer crossed the spread and red when the seller did. The side comes from the exchange wherever it states one reliably, and from the print against the live touch where it does not.
Best bid and offer, the live book down the right edge, candles, VWAP, traded volume, book imbalance, volume profile, cumulative delta and level strength. Each one is a toggle, because a chart with everything on is a chart nobody can read.
Walls marked where they rest, with a gauge that fills as the tape eats into them, every read from above at the price and moment it fired, and liquidations as bursts pointing the way they pushed price. This layer is Elite.
A liquidity heatmap needs full depth many times per second and prints that carry the aggressor side. For crypto both are free and public: no key, no quota, no per-user permission. Your terminal subscribes through our relay, which holds one upstream connection per market and records none of what passes through it. Binance and Bitget refuse datacenter traffic, so their feeds open from your own connection instead.

Bars scale to the largest row on screen, and traded volume per level sits beside resting size.
Exchanges that publish every fill separately produce a tape of four decimal quantities with no sense of scale. Every print and every alert here is measured in quote currency, and the floor can follow what has actually been printing on the instrument.
Volume profile down the side and cumulative delta underneath, both computed from the same prints the tape is listing, so the three of them cannot disagree about what traded.
