Auto-note //Sitting below zero-gamma (49.25) — dealer hedging chases moves below it. The 50.00 call wall is the nearest-expiry ceiling heuristic; 50.00 is the floor. Options price ±2.0% into Sep 18. Dark-pool short volume at 52% and above vs its 20-day.

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