Detailed Description

Black volatility surface that implies an ATM vol based on triangulation.

This class is used when one wants to proxy a volatility like XAU/EUR using XAU/USD, EUR/USD and a correlation. It uses the cosing rule. The correlation can be implied from a vol (if you had XAU/EUR) or historically estimated. This class is just ATM, otherwise there is a degree of freedom in selecting strikes.

One application of this is SIMM sensis, where the vol for XAU/EUR must be broken down into XAU/USD and EUR/USD.

Other methods for building a full surface exist, but to keep things simple we just do ATM

Constructor & Destructor Documentation

◆ BlackTriangulationATMVolTermStructure()

BlackTriangulationATMVolTermStructure ( const Handle< BlackVolTermStructure > &  vol1,
const Handle< BlackVolTermStructure > &  vol2,
const Handle< CorrelationTermStructure > &  rho,
const bool  staticVol2 = false 
)

Constructor takes two BlackVolTermStructure and a correlation.

Attributes like referenceDate, settlementDays, Calendar, etc are taken from vol1
