COW liquidity heatmap, live and free.
Yes. Basis draws a free, live COW liquidity heatmap from Binance’s COWUSDT perpetual order book: resting bids and offers recorded once a second, so you can watch walls build, hold, get pulled or get traded through, with the tape and the trades on top. No account, no trial, no card.

Largest COW 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 COW
- 1
Range: Auto, at ±100 bps
Auto sits at its ceiling of ±100 bps here. COW’s nearest 1,000 levels reach about 100% below and 4190% above price, further than the heatmap’s widest view, so the whole window is real data. Narrow it to ±25 or ±50 bps when you want the walls next to price drawn in finer rows.
- 2
Time span: Fit
Keep the span on Fit, which grows with the recording to fifteen minutes. That reach is 103 times COW’s typical fifteen-minute move of 0.97%. Price rarely travels past the recorded levels in that time, so the full window stays filled while walls build, hold and get pulled.
- 3
Trade bubbles: from $500
Set Minimum cluster to about $500. COW turns over about $115 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 COW’s book
The largest bid within the heatmap’s widest view sits at 0.1156, 0.82% below price: $16K, 2% of everything published on that side and about about 2 minutes of average COW 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: 57% of the size within ±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 COW the heatmap is where you see whether the heavier side stays when it is tested.
The COW book is thin: about $63K rests within half a percent of price. On a book like this one order can be most of a level, walls appear and vanish within seconds, and a bright band is a reason to look closer rather than a level to lean on.
COW has traded as a Binance perpetual since November 2024. On younger contracts the book is often provided by a few market makers, so size tends to move in blocks: a wall that steps back as price approaches is common, and a wall that is hit and refilled at the same price says more than one that simply sits there.

Questions
Is the COW liquidity heatmap really free?+
Yes. The heatmap, depth of market and Time & Sales are free for COW 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 COW 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 COWUSDT book, recorded as they change. Reported COW liquidations are marked on the same timeline, so a model is never mistaken for the book.
Are COW 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 COW heatmap reach?+
As far as Binance publishes: the nearest 1,000 price levels on each side. On COW they reach about 100% below and 4190% 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 COW 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 COW and watch the walls
The button opens the Order Flow workspace on COWUSDT: the heatmap starts recording at once, with the ladder and the tape beside it. Give it a minute before reading anything into the picture.
