Real QuantLib::bachelierBlackFormula ( const boost::shared_ptr< PlainVanillaPayoff > &  payoff,
Real  forward,
Real  stdDev,
Real  discount = 1.0 

Black style formula when forward is normal rather than log-normal. This is essentially the model of Bachelier.

Bachelier model needs absolute volatility, not percentage volatility. Standard deviation is absoluteVolatility*sqrt(timeToMaturity)
