Auto-note //Sitting below zero-gamma (1,610.00) — dealer hedging chases moves below it. The 1,670.00 call wall is the nearest-expiry ceiling heuristic; 1,520.00 is the floor. Options price ±5.3% into Sep 18. Dark-pool short volume at 55% 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.
