Auto-note //Holding above zero-gamma (48.75) — dealer hedging dampens moves above it. The 50.00 call wall is the nearest-expiry ceiling heuristic; 47.50 is the floor. Options price ±2.6% into Sep 18. Dark-pool short volume at 80% 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.
