MCVarianceSwapEngine

class MCVarianceSwapEngine(GeneralizedBlackScholesProcess process, Size time_steps=Null[Integer](), Size time_steps_per_year=Null[Integer](), bool brownian_bridge=False, bool antithetic_variate=False, Size required_samples=Null[Integer](), Real required_tolerance=Null[Real](), Size max_samples=Null[Integer](), BigNatural seed=0)

Bases: PricingEngine

Variance-swap pricing engine using Monte Carlo simulation

as described in Demeterfi, Derman, Kamal & Zou, “A Guide to Volatility and Variance Swaps”, 1999 TODO define tolerance of numerical integral and incorporate it in errorEstimate

Test returned fair variances checked for consistency with implied volatility curve.
