US 100 order book heatmap
Swiftedge Depth draws the order book of the US 100 perpetual as a heatmap. You see the limit orders waiting at each price near the market, a fresh column four times a second, and every trade on top as a bubble. It is free, runs in the browser and needs no account.
Open the live US 100 heatmapA new column every quarter second, at least 24 hours of history, every trade as a bubble.
Open US 100 DepthWhat the US 100 heatmap shows
Time runs from left to right and the US 100 price runs up the side. Every thin horizontal band is one price level of the futures book, out to about 2 % from the price, shaded by how much is resting there: green below the price for bids, violet above it for asks. The brighter the band, the more size is waiting. On top of the book you can draw the price as a line, as candlesticks from 1 second to 4 hours, or as a footprint chart. Trades appear as bubbles, teal when a buyer took the ask and violet when a seller hit the bid, and bigger trades make bigger bubbles.
The indicator menu is the same as for Bitcoin. Liquidations marks forced closes of leveraged US 100 positions. Positioning draws where leveraged US 100 positions would be liquidated. VWAP and CVD show where volume traded and which side was aggressive, and the footprint chart adds diagonal 300 % imbalances, stacked imbalances, the point of control and delta. Alerts and 26 drawing tools work here too.
What sets the US 100 book apart
- Open around the clock, busiest in US hours. The US 100 perpetual trades 24/7, also when US stock markets are closed. The busiest hours are the US stock market session, 9:30 AM to 4:00 PM ET, and US data releases at 8:30 AM ET. At night and on weekends the book is usually thinner, so walls are smaller and easier to pull.
- A perpetual, not the index. The book is the US 100 perpetual future. It follows the US 100 index it is built on, but its walls are orders in the perpetual, not in index futures or in the stocks themselves.
- Levels in index points. Prices are index points; sizes are counted in units of the index, where one unit is worth the index price in dollars.
- Positioning on a smaller base. Fewer leveraged positions are open in US 100 than in Bitcoin, so the upper wall, lower wall, flip and max liquidation rest on fewer positions. They are on US 100 positioning and US 100 levels today.
How to read it, step by step
- Look for bright bands close to the price. Large resting orders show where US 100 may slow down. A band that has stood for several minutes says more than one that just appeared.
- See what happens when the price gets there. If trades hit the band and it holds, the liquidity was real. If it vanishes just before the price arrives, it was pulled, not filled.
- Read the bubbles. A cluster of large bubbles at one level shows who is in a hurry. Heavy buying into a violet band while the price stays put means sellers are absorbing it.
- Add context. Turn on Liquidations to see forced buying and selling, CVD to follow the aggressive side, and Positioning to see where leveraged positions would be liquidated.
US 100 liquidations on the heatmap
With the Liquidations indicator, every forced close is drawn as a ring at the time and price it happened: orange when a long was closed, cyan when a short was. Estimated levels where leveraged positions could be closed next are on the US 100 liquidation heatmap.

Is there a free US 100 order book heatmap?
Yes. Swiftedge Depth shows the live US 100 perpetual order book heatmap for free in the browser, with no sign-up, at swiftedge.uk/us100/depth.
Which market does the US 100 heatmap show?
The US 100 perpetual futures order book and every trade. Everything Swiftedge shows is its own calculation on public perpetual futures data from Hyperliquid and Lighter; the FAQ lists the sources.
Is this the same as a US 100 liquidation heatmap?
No. An order book heatmap shows orders that are actually resting in the book. A liquidation heatmap estimates where leveraged positions could be closed by force; Swiftedge has that as a separate page, the US 100 liquidation heatmap.
How far back can I scroll?
At least the last 24 hours. Candlesticks run from 1 second to 4 hours.
