## TL;DR

Hi HN, I'm Weilun, cofounder of OpenChart.

## Summary

Hi HN, I'm Weilun, cofounder of OpenChart. We built OpenChart because we wanted Claude and Codex to interface with the markets, like most of humans do, through charts rather than through CLIs. With your existing AI plans, your agent can work directly with your charts: annotate a setup, write an indicator, investigate a market move, or create an alert. The chart, conversation, and research live in the same workspace. OpenChart alerts on any market move: draw any shape on a chart and attach an alert. When price crosses it, the alert triggers your agent to investigate the move and save the research in your workspace. The agents can work with charts, indicators, and alerts. Custom indicators and alert conditions are written in [Tea](https://github.com/longsurf-ai/tea), a programming language we built for the markets. We believe software shouldn’t impose artificial friction on your workflow.

## Nauti's Take

The useful first test is a tightly scoped alert workflow using historical price moves. Check whether the agent produces reproducible analysis with sufficient context and whether Tea can express your actual conditions. Before relying on it in production, verify the data sources, latency, alert reliability, and how much your existing Claude or Codex plans really cover.
