# JavaScript financial charting libraries

> Candlestick, OHLC and trading charts with indicators for the browser. 9 tools, ranked by GitHub stars.

Charting libraries built for market data: candlestick and OHLC series, volume panes, technical indicators, drawing tools such as trend lines, and fast panning and zooming over long price histories. Most render with Canvas or WebGL to stay smooth with years of tick or minute data.

Check which indicators and drawing tools ship built in versus as plugins, whether real-time updates and streaming data are supported, and the license: Lightweight Charts from TradingView is Apache-2.0, while some trading platforms offer only their full charting product under a commercial license. General-purpose libraries such as Apache ECharts and Plotly.js also draw candlesticks when you need finance alongside other charts.
