Largest BTC walls within 1% of price
The three largest resting levels on each side inside the heatmap’s widest view, as of the snapshot above. Walls move and cancel; the heatmap shows what they did next.

Heatmap settings that fit BTC
- 1
Range: Auto, about ±17 bps
Leave the range on Auto: it shows about ±17 bps, which is how far BTC’s nearest 1,000 levels reach on the thinner side (0.17% below, 0.17% above). A wider fixed range adds rows Binance never published, and those draw as grey, not as empty book.
- 2
Time span: 1m
Use the 1m span. That reach is 0.8 times BTC’s typical fifteen-minute move of 0.20%. The book is shallow against how far BTC moves, so any longer view shows grey wherever price left the recorded levels. One minute stays continuous, and the walls that matter are the ones next to price anyway.
- 3
Trade bubbles: from $500K
Set Minimum cluster to about $500K. BTC turns over about $101K a second on an average day, so that floor keeps trade clusters of roughly 5 seconds’ turnover or more. The bubbles left on screen are the bursts worth checking against the walls they hit.
Reading Bitcoin’s book
The largest offer within the heatmap’s widest view sits at 77,009.3, 0.13% above price: $3.0M, 7% of everything published on that side and about 30 seconds of average BTC trading. A burst of selling or buying can work through it in under a few minutes, which makes the moment price touches it worth watching on the tape as well as the heatmap.
The book is close to balanced: 51% of the size within ±0.1% rests on the bid. Read that as a fact about resting orders at the moment of the snapshot, not as a forecast. Displayed size is often cancelled as price approaches, and on BTC the heatmap is where you see whether the heavier side stays when it is tested.
Bitcoin is the primary liquidity and risk benchmark for the crypto market; its structure often determines whether altcoin signals deserve risk.
The common mistake: Treating the benchmark as isolated from liquidity, macro conditions or cross-market positioning. Macro repricing and liquidation cascades can invalidate otherwise clean intraday levels faster than a trailing indicator reacts.

Questions
Is the BTC liquidity heatmap really free?+
Yes. The heatmap, depth of market and Time & Sales are free for BTC and every other crypto perpetual in Basis: no account, no trial and no card. The book is recorded in your browser from Binance’s public stream, so there is no per-user server cost to charge for.
Is this a BTC liquidation heatmap?+
No. A liquidation heatmap estimates where leveraged positions would be forced out, from a model of entries and leverage. This heatmap draws resting orders that are actually in Binance’s BTCUSDT book, recorded as they change. Reported BTC liquidations are marked on the same timeline, so a model is never mistaken for the book.
Are BTC order book walls real or spoofed?+
Public order book data cannot say who placed an order or whether it will stay, so no tool can label a wall genuine. What the heatmap shows is behaviour: size that holds while it trades, size that refills at the same price, and size that disappears as price approaches. Basis marks those changes as liquidity events so they are easy to find.
How far does the BTC heatmap reach?+
As far as Binance publishes: the nearest 1,000 price levels on each side. On BTC they reach about 0.17% below and 0.17% above price right now. Anything beyond that was never sent, so it draws as grey rather than as an empty book, and recording starts when you open the heatmap because Binance keeps no order-book history.
Can I watch the BTC heatmap on my phone?+
Yes. The Order Flow workspace runs in the phone’s browser with the heatmap on top and the ladder and tape below. Phones pause background tabs, so recording stops while you are in another app; keep Basis in front while you watch and it reconnects when you return.
Open BTC and watch the walls
The button opens the Order Flow workspace on BTCUSDT: the heatmap starts recording at once, with the ladder and the tape beside it. Give it a minute before reading anything into the picture.
