Free chart widgets
Put a live footprint chart on your site. Free.
Embed a live Basis chart your readers can actually use: they draw on it, add indicators, replay the market bar by bar and switch between the price chart, an exact bid × ask footprint and a live order-book heatmap. Any size, no account, no API key. Pick where it starts, copy one snippet.

A chart your readers can use
You choose the market and the view it opens on. From there it is the reader’s chart, with the same engine and tools as the Basis terminal.
Draw on the chart
70+ drawing tools: trend lines, channels, Fibonacci and Gann, chart patterns, long and short positions, measurements and notes, with undo and keyboard shortcuts.
Add any indicator
Search the full library of 200 indicators, add as many as they like and tune every setting.
See the exact footprint
Bid and ask volume at every price inside each candle, with delta and imbalances, from Binance’s own trades.
Watch the order book
A live heatmap of resting orders, every trade as it prints, liquidations and cumulative volume delta.
Replay the market
Pick any bar and play the chart forward from it, bar by bar or at up to ten times speed, with the indicators and the footprint replaying too.
Choose the right interval
Price-chart intervals depend on the venue, with one-second through monthly and price-range options where supported. Exact footprint and volume-profile views run from one-minute to hourly bars.

Questions
Is the Basis chart widget free?
Yes. Embedding is free, with no account and no API key. Every widget keeps a small Basis bar with a link back; that is what keeps it free.
Can my readers use the chart, or only look at it?
They can use it. Readers draw on the chart, add and tune indicators from the full library, change the interval, replay the market from any bar and switch between the price chart, the exact footprint and the order-book heatmap. You choose where it starts; you can also turn the reader tools off for a clean chart.
Which markets and exchanges can I embed?
Supported crypto spot and perpetual pairs from Binance, Bybit, OKX and Hyperliquid for price charts. Footprint and volume profile use Binance crypto spot or perpetual data; the heatmap uses Binance perpetuals only. Paid stock and commodity charts are not included in public embeds.
Can I make the chart any size?
Yes. By default it fills the width of your column at 520 pixels tall. You can pick another height, keep an aspect ratio such as 16:9, or set an exact width and height; a fixed-size chart still narrows on screens that cannot fit it. The size is plain HTML in the code, so you can change it later without coming back here.
Will the widget slow down my page?
The generated iframe loads lazily near the viewport. Active charts still use browser CPU and network resources, especially trade-heavy views. Start with one widget, give it a suitable height and test your published page on mobile.
Does it work on WordPress, Notion and other sites?
Use the iframe code on a site that permits custom HTML. WordPress.com requires a paid plan with hosting features activated for iframe HTML; self-hosted WordPress may restrict it by user role. In Notion, paste the widget link into an Embed block, not the HTML. Email inboxes generally do not run iframes; link to the web page instead.
Is historical order flow available immediately?
Trade history loads progressively and coverage is bounded. Footprint needs executed trade data; volume profiles may be estimated until complete trade coverage is available. Heatmap book history accumulates while running—it is not a 24/7 historical depth archive. Check the coverage and connection labels.
Can I remove the Basis branding?
No. The Basis bar inside the chart stays, and the one-line credit under it is part of the code. You can change everything else: market, chart, interval, indicators, theme and size.
Want the whole terminal, not one chart?
The footprint, heatmap, derivatives and 200 indicators the widget comes from are free in Basis.
