IV Term Structure

Power-law: σ(T) = σ_ref × (30d/T)^ζ. Affects all expiries in sim mode.
ζ > 0 → inverted (short IV higher, typical high-vol stock). ζ = 0 → flat.

ζ +0

IV Surface — Strike Shape

Controls how IV varies across strikes at a given expiry (shape of the smile).

Spot-Vol Correlation Band

Grey band on P&L chart shows how IV moving with spot changes outcomes. ρ>0: spot up → IV down (leverage effect). ρ<0: spot up → IV up (momentum/FOMO).

ρ 0.75

IV(S') = IV₀ × (S/S')^ρ · ρ=0: no change · ρ=0.75: typical equity (vol crush on rally) · ρ<0: momentum regime (vol spikes on rally).

Heatmap Mode

Vol-Correlated: each heatmap cell uses IV adjusted for the scenario spot using ρ above.

Model note: Black-Scholes (European approx). US equity options are American-style. High-IV stocks (>60%) may show model deviations near expiry.
