Opus 5.5 + Jev trading bot detects when its edge dies
A research paper and dependency-free Rust codebase show how Opus 5.5 + Jev can score every trade against real outcomes and cut position size to zero when the edge disappears, surviving all 500 simulated paths where a normal bot was ruined on 38.6%.

everyone is building 24/7 trading bots with opus 5.5 + jev and almost NOBODY builds the one part that keeps them alive the part that notices when the edge is DEAD i wrote a 6-page research paper on exactly how to make opus 5.5 + jev score every call against real outcomes and cut size to zero when the edge disappears along with the COMPLETE CODEBASE in RUST, zero dependencies 500 simulated paths, edge silently killed mid-run. normal bot got ruined on 38.6% of them. this one on 0%:
