Some missing or invalid quantity and premium fields become zero during normalization; totals can omit those values. Zero or unavailable totals do not establish that no trading occurred.

Term structure — ATM implied volatility

At-the-money (ATM) implied volatility (IV) uses the strike nearest each expiry's forward price. Each point averages available call and put mark IV in percent. Different expiry dates can have different IV; the slope does not predict price direction.

Volatility by strike — 2026-10-27

Mark IV by strike for the nearest expiry with at least two rounded days remaining. Puts use amber; calls use blue. The bulk feed omits per-option delta, so this chart does not calculate 25-delta skew. The methodology defines the selection rules.

Days left rounds to 0.1 day from collection to 08:00 UTC on the expiry date. OI means open interest. P/C means put/call ratio. A dash means no positive OI value or an undefined ratio. The methodology explains missing-value limits.

How to read this page

Implied volatility (IV) is the model volatility associated with an option price. Mark IV uses Deribit's mark price. It does not show the price available for an order or predict direction.

Term structure compares at-the-money (ATM) mark IV across expiry dates. The strike curve compares call and put mark IV at different strike prices for one expiry. Neither chart establishes trader intent.

Open interest (OI) measures outstanding contracts. The headline and expiry tables show USD notional value; strike bars show BTC or ETH quantity. Put/call ratios compare put activity with call activity. A missing or zero call denominator produces an unavailable ratio.

One hypothetical BTC volume calculation

Assume two BTC option contracts trade at a purchase price, or premium, of 0.01 BTC each. Assume both the forward price and the conversion index price equal $100,000 per BTC.

Contract quantity: 2 contracts × 1 BTC = 2 BTC.
USD notional volume: 2 BTC × $100,000 = $200,000.
Premium volume: 2 × 0.01 BTC = 0.02 BTC, or $2,000 at the assumed index price.
IV is a separate percentage. It does not enter either volume calculation.

These assumed trades illustrate units. They are not observed market activity. Actual premium volume comes from Deribit's volume_usd field; current mark prices cannot reconstruct past trade premiums. Sources: the book summary fields and calculation method.

The dashboard shows a current snapshot. Historical charts use PerpFinder's stored observations, with coverage and first-observation labels. Deribit's older DVOL candles are external history and are outside that collected series.
