this f*cking Wall Street quant made a regime trading system that switches between Trend, Range, and Stress playbooks in real-time using HMM + JEV + Opus 5.5 making $32k/m solo. he revealed how his "3-layer architecture" uses Reflex (deterministic engine) → Brain (Opus 5.5 nightly research) → Guardrails (hard limits + kill switch) so AI never touches live execution. Bookmark before its lost.
