A Monad order-book trading bot built in 72 hours
The developer had Opus 5.5 write everything computable, while Jev answers six structured questions per 300ms block in 81ms, a plain-code risk engine can veto any call, and each block costs about $0.00002.
the best ai trading bot of jev's launch week never lets the ai trade one developer shipped it in 72 hours: it reads a live order book on monad and makes a decision every 300 ms block a chat model needs 3-30 seconds to think about an order book, by then the book has moved dozens of times / jev answers in 81 ms the trick is the split: opus 5.5 writes every piece that can be computed, jev only answers six typed questions per block, and a risk engine in plain code can veto all of it six judgments / one call / ~$0.00002 per block the model makes the call, but the code is the only thing allowed to say yes
