A New Algorithm for Computing Implied Volatility

In this study, we simplified the Black-Scholes formula to a two-input version. This simplified formula presents a one-to-one relationship with one input given that the other input is fixed. With this simplified formula, we created an option-price data grid and showed that the implied volatility can be obtained by interpolation. This interpolation-based algorithm does not require iteration and has an adjustable accuracy, which is very useful in computing implied volatilities for a large number of options in a real-time environment
