OpenChart is an open-source trading platform that combines interactive charts, alerts, and programmable AI agents to support market research and automated monitoring. It offers a desktop app (free) and a self-hosted build workflow (Node.js, Bun, Just) and removes software-plan limits on charts, indicators, and alerts while leaving AI usage to users' chosen model providers and optional cloud market-data pricing. Key visual features include multi-indicator charts with Volume Profile and a 4×4 chart grid. The project includes a custom scripting language, Tea, for writing indicators and streaming monitors with functions, loops, state, and collections, and the repository is distributed under an OpenChart License based on Apache 2.0 with additional conditions and optional commercial licensing.
The platform integrates external models (examples: Codex, Claude, Gemini) so plain-language requests produce Tea monitors, alerts, and agent research workflows that annotate price ranges with source-linked findings. Typical workflows let users draw zones or set conditions that trigger agents to investigate breakouts, expand annotations, or run opportunity-discovery research. The codebase invites contributions to code, indicators, and documentation, documents security reporting procedures, and points to community channels (Discord, GitHub Issues, Reddit) for support. The README credits inspirations (Pine Script, OpenCode, Effect, UI libraries) and includes development and packaging guides for contributors.
