Opus 5.5 blows up a $10k account alone; adding Jev risk control returns 6.2%
In the same market with the same model, two $10,000 paper accounts diverged: pure Opus was liquidated in 17 hours, while the Jev-managed lane gained 6.21% over 24 hours with a 1.9% max drawdown.
Opus 5.5 blew up a $10,000 account in 17 hours. Opus 5.5 + Jev made +6.2% on the same trades. Then Opus told me why it lost. "Lane A is down 3 in a row. Raising leverage to 15x to recover the drawdown." That's a direct quote from the smartest model on the planet. 2 hours later it was at 20x. Then $0.00. Here's the setup. Paper account, two lanes, $10k each, same model, same prompts, same market: A → Opus 5.5 alone B → Opus 5.5 + Jev deciding risk Hour 8: Opus alone is up 13%. The Jev lane is barely moving. I almost killed the test. Hour 11: both lanes take 3 losses in a row. Opus alone doubles down. 10x. 15x. 20x. Jev puts lane B in a 4h cooldown and blocks every oversized order after. Hour 17: lane A liquidated. Hour 24: lane B +6.21%, max drawdown -1.9%. Same brain. The only difference was something that could say no. Intelligence isn't risk management. Your agent will revenge trade too.
