Saved historical replay · not live · GEX as_of 2026-03-05T15:30:00 · levels as_of 2026-03-05T15:30:00
GEX scope: All expirations. Wall scope: All expirations. The levels endpoint has no expiration filter.
GEX flip certification is absent in this saved schema; no certified regime is inferred here.
Per-strike net GEX
Blue: positive · red: negative · dashed black: spot · dashed purple: GEX response flip, when published. Chart shows strikes within ±15% of spot when available; totals and flip cover the GEX request scope.
Read the assumptions
Structural GEX uses settled open interest and the fixed calls-positive / puts-negative convention. It is not an observed dealer inventory. A gamma flip is a repriced underlying-price boundary, not a crossing of the bars or their cumulative sum. Missing levels remain missing; this dashboard does not create trading signals.
