IV term structure

At-the-money implied volatility per expiry.

Volatility smile

IV by strike — expiry 2026-11-20. A steep left side = expensive downside protection.

Daily ATM IV (~30 DTE bucket) collected since March 2026. Rising IV into an event = the market bracing; collapsing IV after = the crush.
