This app evaluates and graphs historical volatility surfaces over time. After start date, stock symbol, volatility expiry tenor and interval tenor are chosen, the app calculates the at-the-money volatilities ranging from 50% to 150% at-the-moneyness. Users can choose to display the volatilities in a graph, popup table or Excel file, or any combination of the three.
