Options positioning & squeeze sensitivity
Nearest expiration after today within 30 calendar days; same-day expirations and later maturities are excluded.
A complete options reference is unavailable.
Open interest has both a buyer and a seller; it does not reveal dealer hedge direction. Gross gamma sums both calls and puts without netting and uses a local 1% price-change approximation. It measures sensitivity, not predicted buying or a squeeze probability.
Assessment prepared 2026-11-05 04:02 UTC. Options model values may come from a cached snapshot; their original computation time is not supplied. Open interest has its own effective date.
