Calculation methodology

Options historyIV: ThetaData historical Greeks, equal-weight mean of call/put 50-delta IV across the next four listed Friday-cycle expirations, including holiday shifts verified against ThetaData’s market calendar. Missing inputs leave gaps. Skew: equal-weight mean of put minus call IV across those four expirations. IV-implied move history: mean of each expiration’s average call/put IV multiplied by the square root of remaining calendar days divided by 365.25; percentage of spot, not a quoted straddle premium.
