All expiries combined. Amber lines mark the call and put walls; the dashed line is spot.
At-the-money implied volatility per expiry.
IV by strike — expiry 2026-10-30. 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.
