Volatility
A focused reading path through the options data reference.
Read about the context that makes an implied-volatility field interpretable: its scale, underlying reference, observation time, and calculation assumptions. The Bitcoin article examines surface construction and sparse observations, while the fixed-income guide adds quotation conventions and curve inputs. Keep observed points distinct from interpolation and provider metrics distinct from internally calculated values. A smooth surface is a visualization of a dataset and methodology, not evidence of guaranteed future behavior. Use the linked guides to make the inputs and exclusions visible before comparing outputs.
