Auto-note //Holding above zero-gamma (132.50) — dealer hedging dampens moves above it. The 135.00 call wall is the nearest-expiry ceiling heuristic; 130.00 is the floor. Options price ±3.1% into Sep 18. Dark-pool short volume at 59% and easing vs its 20-day. The pullback screen flagged a reclaim candidate on Sep 14. The falling-knife screen has it turned after a 39% sell-off.
Composed from the nightly pipelines — every panel degrades independently when its dataset is missing. Heuristics labeled as heuristics; not investment advice.
