Webfreeglobal

OpenCharts is an open-source, self-hosted trading-terminal UI with advanced charting, a full drawing-tool suite, and a built-in paper-trading engine seeded with real historical market data, running entirely as a static site with no backend or signup required. It's aimed at traders wanting a free charting/paper-trading sandbox and at developers who want a ready-made terminal UI to wire up to their own trading backend.
