Black-Scholes Formula for Valuing European Options
This program implements the Black-Scholes formula which has been used
extensively in option markets worldwide since its publication in the early 1970’s.
The five inputs are simply keyed into the five financial variables and then
t
displays the call option value, and
~
shows the put option value. The option
values produced are accurate to at least the nearest cent for asset and strike prices
under $100.
