Study 1 · Volume profile vs its folklore
Does yesterday's POC attract price more than a random level the same distance away? Does the “80% rule” hold?
- Data:
- GC=F (COMEX gold futures) 5m bars with real exchange volume, 50 full CME sessions (2026-04-29 → 2026-07-10), frozen in-repo
- Sample:
- 50 session pairs; per-pair distance-band random-level controls (K=1,000)
- Control:
- Distance-band random levels [0.8d, 1.2d], real-level ±$2 excluded — redesigned after adversarial review broke the first null
- Limitation:
- One symbol, one 50-session window; bar-resolution volume approximation
Finding: POC touch rate 69.4% vs control 71.5% — the magnet is folklore; the “80% rule” failed all three principled readings; one narrow POC-respect effect graded “suggestive, unproven”
For technical readers — the one-command re-run
