Crypto Options Implied Volatility: Event Time vs Retrieval Time

Implied volatility is computed from a price at a moment, using the underlying price at that moment. An IV without its time and underlying isn't comparable.

Short answer

Deribit's ticker reports mark, bid and ask IV for options with a timestamp, and book summaries include mark_iv with underlying_price and interest_rate used. IV changes with the option price and the underlying; comparing IVs read at different times mixes market moves with volatility changes. Store IV with its timestamp, the underlying price and the IV type, and compare surfaces only from coherent snapshots.

Illustrative: 'ATM IV rose 3 points' compared two different strikes because spot moved; re-centred on the same moneyness, IV was unchanged.

Sources and methodology

Field definitions come from DEX Screener's API reference and CoinGecko's onchain API documentation, read 17 October 2026. Where a schema doesn't document a timestamp, this guide says so and recommends recording retrieval time yourself.

  1. Deribit API: ticker — timestamp, IVs, greeks.
  2. Deribit API: get_book_summary_by_currency — creation_timestamp (ms) per summary.
