Order book heatmap

Resting liquidity painted behind the candles, so you can see the walls price is trading into and whether they hold or get pulled.

What you see

Heat. Brighter means more size resting at that price, at that moment.
Marks. Walls that were pulled or eaten, icebergs and iceberg levels, and sweeps.
Trade dots. Binance taker orders on the candles, sized by volume. Perp book only, off by default.

A wall that keeps getting refilled as price trades into it. That is real interest.
A wall that vanishes just before price arrives. That is a pull, not support.

Book: Perp, spot, Coinbase spot or Binance spot.
Show: Resting size, or what was added and removed.
Colours: Eight schemes, from Classic to Thermal.
Magnifier: Hold Alt to zoom into the book under the cursor, or keep it always on.
Only orders resting at least: 1 to 15 minutes. Quotes that come and go drop out, walls that sat there stay.
Wall sizes and 15m change: Tags by the price scale on the walls resting now, with the change over 15 minutes.
Options levels on the book: Call and put walls, gamma flip and top gamma strikes as lines, boxed where a wall rested near one.

BTC and ETH, on 1 to 15 minute charts and on tick and range bars. Paid plans.
