OpenChart

OpenChart: Desktop charting software that combines price charts with Claude, Codex, and Gemini agents.

OpenChart is a free desktop charting application designed for watching markets. It stores your strategies, alerts, and research locally in a database on your desktop for privacy and security. You can connect your existing Claude, Codex, or Gemini account to run agent workflows, build alerts and indicators, and analyze price anomalies using live streaming data. The software features an open-source language called Tea for custom indicators, multiple panes per chart, and unlimited alerts. It is built by engineers from Google DeepMind and Meta as an alternative to traditional trading platforms.
