Editorial interest 82/100 Selection signal · not a rating of the site

A market-replay tool lets an AI agent trade a recorded session, then scores its performance against buy-and-hold.

Landing page captured for the 2026-09-04 issue.

Field notes

The tool feeds a recorded market session to an agent while enforcing delayed bar arrival, next-open fills, and close-based marking. Its displayed pilot reports 18 arm-days and separates strategy return, buy-and-hold return, and excess return; one example shows +0.0098% versus +0.0053%. The homepage also provides an MCP installation path for Claude Code and Codex, while noting that the simulation is not financial advice.
