I - A Discret Model !

The binomial model is a discret model in a sense that it leads to an option value by scaling the maturity T in n intervals ∆t.

T= n∆t

The larger n, the more accurate the model.



II - Data

S spot
K strike
σ volatility
b=r-q cost of carry
with
r annualized interest rate
q annualized dividend rate



III - The Binomial Model

If T= n∆t, then ∆t= T ∕n

If u is an up factor, d a down factor such as
u=exp(σ√∆t)
d= exp(-σ√∆t)

If p is the risk neutral probability for an up move for the asset during ∆t

p=((exp(b∆t)-d) / (u-d)

And if
m=n-i
Then
