Auto-note //Sitting below zero-gamma (116.50) — dealer hedging chases moves below it. The 120.00 call wall is the nearest-expiry ceiling heuristic; 115.00 is the floor. Options price ±3.4% into Sep 18. Dark-pool short volume at 50% and above vs its 20-day. The falling-knife screen has it turned after a 15% sell-off.
Composed from the nightly pipelines — every panel degrades independently when its dataset is missing. Heuristics labeled as heuristics; not investment advice.
