Deribit
The dominant crypto options exchange, holding the majority of global BTC and ETH options open interest. Deribit standard expiries settle Friday at 08:00 UTC. The DVOL and ETH DVOL volatility indices are calculated from Deribit option prices.
Intrinsic Value
The amount an option would be worth if it expired right now. For a call, max(spot − strike, 0). For a put, max(strike − spot, 0). The remainder of an option price is time value, which decays toward zero by expiry.
ETH
Ethereum, the second-largest crypto asset by market cap and the second-largest options market. ETH options track BTC closely but show distinct skew and term-structure dynamics, especially around protocol-level catalysts.
Expected Move
The implied one-standard-deviation price range over a given period, derived from at-the-money option prices. Calculated as roughly spot times ATM IV times sqrt(time to expiry). Useful for sizing trades and setting stops outside the priced-in noise.
