By expiration · Deribit
Overlay
Plot any subset of option parameters as a function of expiry. Stack ATM IV alongside total OI alongside P/C ratio to spot divergences.
Each enabled series is normalised to a 0–1 unit-y-axis so heterogeneous units (vol %, $, ratio) can overlay on a single chart. Hover labels show the original-unit values for the chosen series. X-axis: days to expiry (log scale). Source: Deribit chain; math from lib/options (R25).
