Auto-note //Sitting below zero-gamma (1,195.00) — dealer hedging chases moves below it. The 1,200.00 call wall is the nearest-expiry ceiling heuristic; 1,150.00 is the floor. Options price ±3.0% into Sep 18. Dark-pool short volume at 45% and easing vs its 20-day. The falling-knife screen has it turned after a 22% sell-off.

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