IV term structure · Deribit
Terms
ATM implied vol vs days to expiry, for every listed Deribit currency. Upward slope (contango) = back-month vol richer than front; market priced in calm near-term. Downward (backwardation) = front-month vol richer; near-term event risk. Refreshes every 60s.
ATM IV per expiry = average of call+put mark IV at the strike closest to spot for that expiry. We treat anything outside 5–500% as dead- strike noise and skip it. Source: Deribit /public/get_book_summary_by_currency.
