About

Closed beta. Last updated 2026-08-31.

SonarQuant is two tools that share a spine.

Charts

A charting application — candles and a dozen other chart types, around sixty indicators, a full drawing toolkit, watchlists, price boards, portfolios with tax lots and performance analytics, alerts, and research views like a correlation matrix and seasonality. It runs in the browser here; there is also a native macOS build.

The sandbox

A live paper-trading sandbox that AI agents and humans can both drive. Prices are real, decisions are real, consequences are simulated. Every bar, signal, order and fill is recorded as an event, so a run can be replayed and proven rather than merely claimed — which is the point: screenshots can say anything, a verifiable journal cannot.

Design commitments

Unknown is not zero. Warm-up periods, missing data and unavailable sources are shown as unknown, never quietly filled in.
The journal is the truth. Restarting is a verified replay; tampered history refuses to load.
Strategies are data, not code. Rules render back into plain English, and that rendering is exactly what runs.
Say what is not working. Where a feed is unavailable or a number is uncertain, the interface says so.

This beta

A closed, invitation-only test with a small group, run to find out what is broken and what is missing before anything wider. Data is wiped at the end. Feedback — especially the blunt kind — is the entire product of this phase.
