About this video
On a new account, Scenario test opens with an editor and the classic strategies. The person starts from tradefloor's momentum bot, which holds the 3 stocks that rose most over the last 5 days, and changes one line so it holds 5.
Three scenarios start on day 20: a VIX spike, a rate shock of +200bp and a recession. Days 1 to 19 are the same on every line. Any difference after that comes from the scenario. The option called In this browser tab runs the Python in the page. Four lines play one after another, one with no shock and one per scenario, and the card fills in as each finishes.
The person then asks the Simulator's own Ask why, ends the simulation and has Claude write the outcome summary from its figures. The long middle of the run is fast-forwarded at 32 times its real speed.

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.
2:20Does my trading bot pass CI?A pull request raises a bot's leverage and tradefloor's stress suite fails it in CI. Claude fixes the bot from the CI log without loosening the check, and CI passes.
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.
