Open source and Pro ​

Everything in this repository is open source under the MIT license and free for any use, including commercial products: the whole chart engine with its series, indicators, drawings, orders, alerts, timeframes, replay and plugins, and the Vue and React components.

A commercial edition, Pro, is in development. It adds packages built on the same public API, for teams that need more than the chart:

ProWhat it adds
Trading terminalA complete terminal UI: toolbars, indicator panel, symbol search, watchlist, replay
Formula engineIndicators and signals written as 通达信-style formulas, computed on every trade
Order flowVolume profile, footprint charts, order book heatmap, delta
Linked layoutsSeveral charts with a synced crosshair, time axis and symbol
Market dataAdapters for exchanges and brokers, history paging, reconnection

Our commitments:

  • What is free stays free. Features released here under MIT stay MIT; none of them will move to Pro.
  • Pro is free to develop with. Try it and build with it at no cost; it shows a watermark online until a license key for your domains is set. Licenses for individual developers cost less than for companies.
  • The extension points stay open. Pro is built on the public plugin API, so anyone can build extensions of their own the same way.

Join the Pro waitlist to get early access and tell us what to build first.
