Auto-note //Sitting below zero-gamma (178.75) — dealer hedging chases moves below it. The 180.00 call wall is the nearest-expiry ceiling heuristic; 185.00 is the floor. Options price ±4.5% into Sep 18. Dark-pool short volume at 40% and easing 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.
