We let an AI rewrite our trading bots. Almost every idea it has is wrong.

Once a day the AI is handed one of our paper-trading bots and must propose exactly one change to it. We backtest that change head-to-head against the original on the same real data, and only a genuine winner is promoted. Win or lose, every attempt is published — the change, the AI's reasoning, and the result it got. Paper money throughout.

1.2%of ideas survived
Roughly 1 in 84 proposals beat the bot it was trying to improve. Most ideas don't work — we think showing you which ones did is worth more than a highlight reel.

Nothing has beaten its original since 16 Jun 2026 — 1,471 proposals ago. We publish the dry spell too.
