Auto-note //Holding above zero-gamma (216.25) — dealer hedging dampens moves above it. The 220.00 call wall is the nearest-expiry ceiling heuristic; 220.00 is the floor. Options price ±3.5% into Sep 18. Dark-pool short volume at 63% and above vs its 20-day. The pullback screen flagged a reclaim candidate on Sep 10. 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.
