Does my trading bot pass CI?
About this video
A pull request raises the momentum bot's leverage from 1.0 to 1.5 times. The pull request's CI job is one command with no AI in it: tfrun momentum.py --suite tf-stress-2026.2 --check max_drawdown<=25%. It plays the bot on 24 markets of 40 days, each with a scheduled shock, and fails if any market falls more than 25% from its peak.
The link tfrun prints opens the run on tradefloor's Benchmarks page, which shows it market by market and gives a verdict. Claude reads the CI log and changes the bot, since it can't run CI itself. The push runs CI again, and Benchmarks sets run 2 against run 1 on the same markets.

The guide
A risk gate for a trading bot in CI builds the same check from scratch, with twelve simulated markets, one drawdown rule and a GitHub Actions job that turns the build red.

2:07Can Claude out-trade a bot?Claude, a momentum bot and a buy-and-hold bot trade one shared market for 25 days, straight through a liquidity crisis.
3:02Skill or luck?Claude tunes a trading bot on 8 public markets and none of its changes beats the original. On fresh hidden markets the unchanged bot scores anywhere from 33 to 51.
