Abstract
To price exotic options consistently to market data, it is necessary to approximate the implied volatility surface (IVS) over the strike–maturity plane. To avoid mis-pricing and arbitrage strategies, the approximation must be arbitrage free. Based on the moving least squares (MLS) reconstruction, a numerical approach is presented in this paper to compute arbitrage-free surfaces which approximate observed market data.
