Free order book heatmap for crypto

What the heatmap shows

The order book lists the limit orders waiting to buy (bids) and sell (asks) at each price. A snapshot of the book only tells you what is there right now. The heatmap records the book over time: each price level is a horizontal band, and the brighter the band, the more size was resting there.

Large trades are drawn as bubbles where they hit, so you can see price, the waiting orders and the aggressive orders together.

What traders use it for

• Spotting large walls of bids or asks that price may react to.
• Seeing liquidity pulled just before price reaches it, a sign the wall was not meant to fill.
• Watching absorption: price hitting a level again and again while the resting size holds.
• Picking stop and target levels around real liquidity instead of round numbers.

Order book heatmap explained covers these patterns with examples.
