Auto-note //Sitting below zero-gamma (91.50) — dealer hedging chases moves below it. The 90.00 call wall is the nearest-expiry ceiling heuristic; 90.00 is the floor. Options price ±3.9% into Sep 18. Dark-pool short volume at 56% and above vs its 20-day. The pullback screen flagged a reclaim candidate on Aug 25.

Composed from the nightly pipelines — every panel degrades independently when its dataset is missing. Heuristics labeled as heuristics; not investment advice.
