Swiftedge Depth — live Ethereum order book heatmap

Swiftedge Depth: live Bitcoin order book heatmap

Swiftedge Depth shows the live Bitcoin futures order book (BTCUSDT perpetual, Binance USDⓈ-M) as a heatmap, with every trade drawn as a bubble sized by volume. It adds a new column four times a second, keeps at least the last 24 hours of history (older hours load as you scroll back) and runs free in your browser with no sign-up. Made by Swiftedge.

What you are looking at

Heatmap: resting limit orders by price and time. Green below price are bids, violet above are asks; brighter means more size.

Bubbles: executed trades. Teal for aggressive buys, violet for aggressive sells; the size is the volume.

Lines and panes: the white price line, the day's VWAP in yellow, traded volume underneath with CVD since 00:00 UTC (the CVD button in the pane's corner) and a depth profile of the current book beside the price axis.

Side panel: Mentor analysis, Session Orbs, GEX options levels, 5-minute flow, buy vs sell and news.

How to use it

Mouse: the wheel zooms time, shift + wheel zooms price, drag pans, double-click returns to live.

Touch: drag to scroll, pinch to zoom time or price, double-tap to return to live, press and hold to inspect a bubble or level. On a phone the bar at the bottom holds Indicators, Draw, Alerts, Share, Chat and More.

today shows the whole day; AUTO-SCROLL follows the live edge and AUTO-SCALE refits the price axis.

indicators or + add indicator opens the catalogue: Liquidity, Bubbles, Executions, VWAP, Mentor, Session Orbs, GEX and Liquidations (real forced closes from Binance, OKX and Bybit). The toolbar on the left has 24 drawing tools, saved in your own browser.

Alerts sets price and large-wall alerts with sound and browser notifications. Share turns the moment under the pointer (or now) into an image card with a link. Chat is one live room shared with Options.

Quick answers

Is it free?

Yes, during the public beta, with no account. A free version will remain available.

Where does the data come from?

Order book and trades from Binance USDⓈ-M futures; options data for GEX from Deribit, OKX and Bybit, one snapshot per minute.

What is GEX?

Estimated options gamma exposure, with the gamma flip, call wall and put wall drawn on the chart. The dealer positioning behind it is an assumption, not a measurement.

Is it financial advice?

No. Depth shows market data and descriptive analysis for information and education. Trading involves substantial risk of loss.

gamma above 1 darkens the ordinary and lets only the walls glow · the floor hides everything below its share of the reference — it is the strongest control if you want to see less · "deep book" controls the band from 0.22 % to 2 % out, which is coarsely resolved — set it to 0 for the near book only

equal brightness on both sides

without this, green glows 55–60 % brighter than violet at the same size, so the sides cannot be compared by eye
