Bachelier Model: Fast Accurate Implied Volatility

“An industrial solution” – provides computation to near machine precision for option prices over an extremely large range! Fast and analytic in nature, employs rational polynomials to determine implied BpVol. Follows the Bachelier model; that is, dF = σdW. A new method for computing implied BP Vol (basis point volatility) analytically has come to light. It is described by […]
