What is a liquidity heatmap?
The heatmap shows resting limit orders in the order book through time. Each column is a moment; each band is a price; brightness is how much size sat there. Bright horizontal streaks are walls — prices where passive traders committed real money and left it standing.
How to read it
Price slows down, bounces, or magnets toward walls, because large players need that liquidity to fill size. The white line is mid price. Circles are Bybit liquidations — green where shorts were force-bought, red where longs were force-sold — and clusters of them fuel the fastest moves on the chart. Dashed lines carry the previous day's key levels. Color is percentile-ranked: the bulk of the book stays dark, and only genuine outliers glow amber.
How the data is collected
The Binance book (top 1000 levels) is sampled every 4 seconds; older history is stored as minute-level maximums so persistent walls survive aggregation while flicker disappears. This is measured depth, not a reconstruction from liquidation prices — an important difference from most «liquidation heatmaps».
Walls, magnets and ghosts
Three behaviours cover most of what walls do. A fresh wall's first touch is the highest-probability bounce. A wall that thins with every touch is being consumed — expect the break. And a wall that vanishes before price ever reaches it was never meant to be filled: information about intent, not support. All three are in the heatmap playbook, with liquidation patterns in the liquidations session.
FAQ
Are these real orders or estimates?
Real resting limit orders from the Binance order book (top 1000 levels), sampled every 4 seconds. Nothing is inferred from liquidation math — what you see was actually in the book at that moment.
Why does history only go back a few days?
The book is sampled live and archived from the moment collection started; the archive keeps up to 7 days of minute-level aggregates and grows continuously.
Can a wall just disappear?
Yes — a limit order can be pulled in milliseconds. Walls that vanish as price approaches were bait (spoofing); a wall that survives a touch is information of a different quality.
What are pdVAH, pdPOC and pdVAL?
The previous day's value area high, point of control and value area low — the price zone where most of yesterday's volume traded. Price reacts to these levels surprisingly often.
Can I share a specific view?
Yes. The Share button copies a deep link with your symbol, window, timestamp and any price marker; PNG exports the chart with a watermark.
