Local Architecture and Model Bring-Your-Own-Key Support
OpenChart provides an unrestricted 4×4 chart grid, Volume Profile analysis, and technical studies that run entirely on local compute. Instead of billing for software subscriptions, the desktop app allows users to supply their existing accounts for Claude, Codex, and Gemini. The software connects these models directly to technical chart contexts without platform middleware markups.
Reactive Automation with the Tea Language
The platform couples agentic reasoning with Tea, a language built by the Longsurf team for financial market analytics. When an engineer defines an alert threshold or draws a support zone, agents can generate Tea monitors that evaluate streaming tick data. If conditions fire, the agent inspects related news, runs statistical routines, and attaches source-linked annotations directly to bar intervals.
