Question 1

What is diCharts?

Accepted Answer

diCharts is a high-performance charting library (SDK) for building trading platforms, crypto exchanges, and financial dashboards. It runs entirely in the browser and renders charts using WebGPU for GPU-accelerated performance.

Question 2

How is diCharts different from TradingView?

Accepted Answer

TradingView's embeddable widget is an iframe hosted on TradingView's servers. Your data passes through their infrastructure, the UI carries TradingView branding, and pricing scales with page views. diCharts is a self-hosted library that runs on your servers, renders on your users' GPUs, and carries zero third-party branding.

Question 3

Does diCharts work with React / Vue / Angular?

Accepted Answer

Yes. diCharts is a vanilla TypeScript library with zero framework dependencies. It integrates with any frontend framework in under 10 lines of code.

Question 4

How large is the bundle?

Accepted Answer

~25 KB gzipped for the full library. Individual components are tree-shakable.

Question 5

Do I need WebGPU to use diCharts?

Accepted Answer

The core candlestick engine uses WebGPU, which is supported in Chrome, Edge, Firefox, and Safari (all modern versions). The standalone chart components (Depth Chart, Heatmap, Sparkline, Donut, Bar Chart, Gauge) use Canvas2D and work in all browsers.

Question 6

How do I stream real-time data into diCharts?

Accepted Answer

diCharts includes a built-in tick aggregation engine. Connect your WebSocket feed, pipe ticks into the aggregator, and diCharts handles the rest — candle formation, time alignment, and smooth rendering.

Question 7

Does diCharts support mobile / touch?

Accepted Answer

Yes. Zoom, pan, and crosshair interactions work with touch and trackpad gestures out of the box.

Question 8

Can I customise the colours and theme?

Accepted Answer

Yes. diCharts ships with dark and light themes, and every colour is configurable through the options API.

Question 9

What chart types are included?

Accepted Answer

Candlestick (with 8 styles: candles, bars, line, area, baseline, hollow candles, Heikin-Ashi, Renko), Depth Chart, Heatmap, Sparkline, Donut Chart, Bar Chart, and Gauge.

Question 10

What technical indicators are built in?

Accepted Answer

SMA, EMA, Bollinger Bands, VWAP, Ichimoku Cloud, RSI, MACD, Stochastic, ATR, OBV, and ADX — 5 overlays on the price chart and 6 oscillators in dedicated sub-panes.

Question 11

Does diCharts send my data to external servers?

Accepted Answer

No. diCharts is a client-side library. It never phones home, never transmits data, and never contacts external servers. Your data stays entirely within your infrastructure.

Question 12

How many candles can diCharts handle?

Accepted Answer

With WebGPU rendering, diCharts maintains 60fps with 100,000+ candles on screen. This is 5-10x more than Canvas2D-based alternatives.

Question 13

Can I use diCharts in a commercial product?

Accepted Answer

The Community Edition is MIT-licensed and free for open-source and non-commercial use. For commercial/proprietary products, you'll need a Professional or Enterprise licence.

Question 14

Is there per-seat or per-view pricing?

Accepted Answer

No. All paid licences include unlimited developers and unlimited end users. There are no hidden usage-based fees.

Accepted Answer

Yes. Ask about our Startup Programme for companies with less than $1M in funding. Contact sales@dicharts.com.

Question 16

What is the difference between Professional and Enterprise?

Accepted Answer

Question 17

How do I install diCharts?
