ATON Charts is the chart engine our trading app uses, written by us from the first line. It draws with WebGL and falls back to the canvas, so it stays smooth on a mid-range phone with thousands of candles on screen. No third-party chart code is inside it.

What you get

• Live candles from your own data, with a live price between updates.
• Your strategy on the chart: ladder orders, the take-profit and stop-loss (a moving one draws where it has been), the entry and every fill. A line off the visible prices is pinned to the edge with its distance, never hidden.
• 65 indicators across trend, momentum, volatility, volume and structure, each with its settings and limits. Four more (funding, basis, open interest, taker flow) draw from series your feed sends.
• Drawing tools: trend lines, rays, horizontal and vertical lines, rectangles, Fibonacci retracements, a measure tool, notes, and long and short position tools.
• Saved layouts, a chart grid with the crosshair in step across charts, and backtest replay that computes every indicator on the bars shown so far, so nothing leaks from the future.
• Dark, Light or Follow system, read from your page's own colours, keyboard control and a screen reader summary.

Three ways to use it

1. The embed widget: one element and one script on any page. See the quickstart.
2. The SDK: window.AtonCharts from the same script, for full control from your own code.
3. React: the <AtonChart /> component.

Every way reads the same data: the feed. Plans set how many indicators, drawings, layouts and charts you can use at once; see plans.
