Spot Order Book Heatmap: Where the Bids and Asks Sit
SOL spot order books: $46.6M of bids and $40.0M of asks rest within 2% of the 104.58 mid, summed across 21 of 29 order book venues.
Every 5 minutes we read the spot order books of Binance, Coinbase, Kraken, Bybit, OKX, Gate, MEXC, HTX, Bitget, Bitstamp, Gemini, Bitfinex, BingX, Crypto.com, Backpack, Binance US, Poloniex, LBank, Bitrue, XT, HashKey, DigiFinex, Bullish, WEEX, Deribit, Aster, Bitvavo, Independent Reserve and BtcTurk and bin them into 0.1% price buckets around the mid price, in US dollars. The heatmap shows how that liquidity moved over the last hours; the walls table names the single largest buckets on each side and which venues hold them; the venue table says how deep each book really reaches, because REST books are shallow on some venues and we do not pretend otherwise.

Depth heatmap
Rows are 0.1% price buckets from 20% below mid to 20% above (the view opens on the inner 5%, drag the price axis to widen); columns are 5-minute snapshots; color is the USD resting in the bucket summed across venues. The white line is the mid price. Bright bands that persist are walls; bands that vanish were pulled.
Full history is a member feature. Members see 24 hours of snapshots with zoom and pan; anonymous readers get the last 6 hours.

Depth by venue
USD resting within 2% of mid on each side, and how far the venue's REST book reaches in each direction. A shallow reach means the venue only exposes the top of its book, not that the book is thin.

Reach is capped at 20% (the bin span).
Held out: the books of LBank, XT, DigiFinex, WEEX, Bullish, Deribit, BingX and Bitrue are recorded here but not summed into the heatmap, walls or 2% totals, because their size is not corroborated: the book is at least half as deep as Binance's within 2% on BTC while the venue has no spot volume in our venue snapshots, or the venue reports more BTC spot volume than Binance.
Methodology and honest limits
Books: the public spot book of every venue named above, read with the deepest request each venue offers; USDT, USDC and USD quotes are all read as dollars. Each level's price times quantity is added to the bucket of its distance from mid; mid is the midpoint of the best bid and ask of that venue. Buckets are 0.1% wide and run 20% to each side of mid.
Coverage: a venue whose book reaches only 0.3% from mid contributes nothing to farther buckets; that is unknown depth, not zero, and the venue table shows the reach so you can read the heatmap correctly. Venues that publish their whole book reach the whole span; the venue table shows which ones do.
Snapshots are 5 minutes apart, so orders placed and pulled inside a window are invisible here; walls can be spoofing and the page does not judge intent. Raw per-venue snapshots are recorded since 2026-09-15, every one is kept, and the paid route sells them; the daily CSV serves the 00:00 UTC rows.
FAQ
Is a wall support or resistance?
A bid wall is resting demand below price, an ask wall resting supply above it. They can act as short-term support or resistance while they stay, and they can be pulled in a second; the heatmap history shows which walls persisted.
Why do some venues look shallow?
Some public REST books return only the top 100 to 1,000 levels, which on BTC can stop well inside 1% of mid. The venue table shows each book's reach; beyond it the book is unknown, not empty.
Is this the same as the liquidation map?
No. The LiqMap estimates where leveraged positions would be liquidated; this page shows real resting spot orders. Both are about where price may react, from opposite sides of the market.
