How these numbers are made
One end-of-day snapshot per session from a 15-minute-delayed feed. A premium is a contract’s last trade, used only if it printed that session, sits above intrinsic value and is in order with its neighbours; deltas are the feed’s own. Expiries are the first at least 30 and 60 days out, and nothing under 30 days is annualized. Not investment advice. Full methodology.
- No contract near 0.30Δ traded this session
- We are building our own daily implied-volatility history (1 of 252 sessions so far); IV rank and percentile need a full year of it.
- Our data provider does not license announced earnings dates, and we do not publish estimates.
- Our data feed carries last trades, not live bid/ask quotes, so we cannot show a spread.
