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.
