OptionIX50 is designed to calculate the fair values of stock options by using the Nobel prize winning Black-Scholes Option Pricing Model". It can be used for both European and American options.
OptionIX50 calculates the fair value as your finger moves on iPad either by typing new inputs, moving the slider (for volatility only), or touching the green bar (for exercise price only). A graphic simulation is created to show the impact on fair values when volatility changes while all others remain unchanged, and the simulation is also animated when you tap the clock button at the bottom right corner (tap the clock again will stop the animation).
