Why do the usual interpolators not work? |
The context is that I have a finite difference result of option prices and now I want to interpolate them. I was thinking that since the option prices are convext against the spot stock price, when we interpolate we should do some kind of a convex interpolation to avoid arbitrage. Am I wrong? Please advise. |

I want to interpolate option prices across stock prices and volatilities. Since option prices are convex w.r.t. spot price, I guess usual interpolation techniques(splines, parabolic, linear)do not apply. I am wondering if there's existing code available for download?
