Surface Scenarios

derivatives-pricer-production.up.railway.app · x402

When to use: book reval on an IV surface under F/rate/time/vol shocks with sticky moneyness|strike|fixed_vol. Vol order: interpolate → volAbs → volRel → smileTwist*k. Greeks are sticky-σ BS Greeks (not smile bump deltas). USDC exact on Solana/Base. Prefer scalar /v1/portfolio/scenario for per-leg scalar σ books.
