What is OpenCharts?
OpenCharts is a browser-based trading terminal that requires no backend server. It delivers candlestick charts built on TradingView's Lightweight Charts library, a full drawing toolkit, eight technical indicators, a watchlist, depth-of-market display, and an order ticket supporting market, limit, and stop orders. A paper trading engine with a $100,000 starting balance and 100× leverage runs entirely in the browser, updating positions on every tick. Real historical OHLC data from Binance is bundled at build time and replayed as a live tick stream. The terminal can be deployed as a static site or embedded in a React application via an npm package. An adapter interface lets users connect custom data and trading backends without forking the codebase.
