AI product Open source
OpenChart is an open-source desktop trading-chart application from longsurf-ai that brings AI agents into market analysis, indicator creation, alerts, and research. Users can connect their own Claude, Codex, or Gemini accounts; describe conditions to watch, and have an agent generate Tea monitors that evaluate incoming market data and investigate when conditions fire. Users can also write custom indicators and conditions in Tea, a language built by the same team for market analysis, and use charts, indicators, Volume Profile, price alerts, and indicator alerts without software-plan quotas. Selecting a chart range lets an agent research the corresponding move and pin annotations with linked sources to the chart, while drawn lines or zones can trigger agent research when price crosses them. The desktop application is free, with AI usage governed by the user's agent-provider plan and optional cloud market data priced separately. OpenChart uses the OpenChart License, based on Apache 2.0 with additional conditions.

A trading chart app with AI agents built in (using your own Claude Code or Codex): describe a market condition in plain English and an agent writes a monitor in its scripting language, and when price crosses a drawn zone, an agent researches the move and annotates the chart with linked sources.
