Claude Code integrates a backtesting engine in 13 minutes (uncut) | Reamer Research

Uncut, sped up, no audio. Recorded 12 September 2026 against Reamer Research 4.2.1.

Claude Code (Claude Sonnet, medium effort) is given the Reamer Research kit and nothing else, no web access and no outside repos, and asked to build a multi-asset statistical-arbitrage strategy from scratch, prove the backtest is deterministic, sweep it across signal and cost settings, explain the worst trade, and emit the full result document. Total time: 13 minutes on the wall clock, top right of the screen.

Chapters

Chapter times are video time. The recording is sped up; the wall clock in the frame shows real elapsed time.
