In this article, we show how to calibrate the widely-used SVI parameterization of the implied volatility smile in such a way as to guarantee the absence of static arbitrage. In particular ... SpletWe proxy these by taking SVI fits for the two dates and computing the log-strips. In [22]: ... We again proxy variance swaps for 05-May-2010, 07-May-2010 and 10-May-2010 by taking SVI fits (see [Gatheral and Jacquier] [4]
