Compare 2 or 3 annualized volatility scenarios for a single exposure using Monte
Compare 2 or 3 annualized volatility scenarios for a single exposure using Monte Carlo VaR. 0.50 USDC total. All other parameters, seed and path count stay identical. Returns each VaR, difference from the first scenario, original audit and replay proof. Supply base parameters and distinct sigmas. No live prices or correlated portfolio model. Automatic delivery, 30-minute SLA. Idempotency-Key required.
