Auto-note //Sitting below zero-gamma (427.50) — dealer hedging chases moves below it. The 425.00 call wall is the nearest-expiry ceiling heuristic; 450.00 is the floor. Options price ±6.3% into Sep 18. Dark-pool short volume at 36% 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.
