Free Crypto Order Book Heatmap and Aggregated Depth — a Bookmap Alternative in the Browser

Order book heatmaps show where large orders rest and how they move over time. Desktop tools do it well for one exchange or a few. In crypto, liquidity is split across dozens of venues — so the useful picture is the sum.

Why aggregate the order book

A wall on one exchange can be a few percent of the real liquidity at that price. When the same level holds orders on ten venues at once, it matters far more. AggPro sums 20+ exchanges into one ladder in real time, normalizes contract sizes and shows which venues hold each level.

What you see

• Walls: large resting orders highlighted in the book and on the chart.
• Cumulative depth: hover a price to see dollars and coins between the current price and that level.
• Liquidation map and live liquidation bubbles on the same chart.
• Order book history on the chart: where liquidity stood in the past.
• Spoofing hints: walls that appear and vanish without trading.
