Live order book
The resting orders behind the price, updated several times a second: every bid and ask near the market on Binance, Bybit and (for perpetuals) Hyperliquid, what crossed the book moment by moment and the prints that mattered. Pause it, or go back to any moment of the last seven days.
The live order book is included with Pro
Several times a second it shows where the resting orders sit around the price on the largest venues, how much crossed the book, and the big prints as they land, with an optional sound. Pause it, or go back to any moment of the last seven days.
Ladder
US dollars resting in each 0.01% band nearest the mid
Big prints
Taker trades of $100k or more on the venues we collect. Set a sound to hear them land, higher for buying, lower for selling.
How to read it
Bright bands in the heatmap are prices with a lot of resting liquidity. A band that stays bright while the price trades into it is a wall holding; one that disappears just before the price arrives was pulled. The bubbles show which side was the aggressor, moment by moment, at the price it paid: heavy buying into a bright ask band that does not move is the picture of absorption.
The ladder is the same data as numbers: each row is one 0.01% band of the book. Pause holds the picture and lets you scrub back through the last quarter of an hour. Go back to any moment of the last seven days and step through it at normal speed, four times or sixteen times faster, with the ladder, the bubbles and the big prints as they were.
Where the data comes from
A feed of our own follows the live order books of Binance and Bybit, plus Hyperliquid for perpetuals, and walks them four times a second, adding the books together around each venue’s own mid price. On Bitcoin perpetuals the depth the venues publish stops about 0.2% from the mid; further out the bands are built from the changes published since our connection opened, so they can understate what is really resting. The status line shows the pace the frames are really arriving at; when the machine is busy they can come more slowly. Binance sends its book changes in tenth-of-a-second batches, and Hyperliquid publishes its book about every five seconds, so its part of the composite moves at that pace. Bubbles use the taker trades of those venues; the big prints list comes from the market tape. A book that is resynchronising drops out for those moments. Coinbase, OKX and Kraken are not part of this composite. Replay keeps every frame for seven days: not every order, not every trade, but the book and the flow as they stood every quarter of a second.
