1 Trinomial Trees and Lattices
Pretty much everything parallels the Binomial Tree from a conceptual sense. If the stock price at discrete time step k is denoted by Sk. In this case, the process Sk is specified as
with probability pu, with probability pd, with probability 1 − pu − pd.
Just as with the binomial tree whose leaves can be combined to form the binomial lattice, you can get a trinomial lattice from a trinomial tree. To ensure the martingale property
E{Sk+1 | Sk} = R × Sk,
where , as with the Binomial Tree. We need to assign[1]
Just as with the binomial lattice. you can use (k,i) to denote an arbitrary vertex on the trinomial lattice. The vertex (k,i) is connected to {(k + 1,i + 1),(k + 1,i),(k+1,i−1)} with the appropriate probabilities along the appropriate arcs. If V (k,i) is value of the option at (k,i), for the european call option we have the recursion
if (k,i) is a terminal node otherwise
The option price is V (0,0).
You are going to do a little more than this for this programming assignment.
2 Part 1: Pricing an American-Option using a Trinomial Model by Recursion
Using my C++ program american option pricing by binomial model.cpp on Compass as reference, write a C++ program that takes as command-line input the values of T,N,r,σ,S0 and K, and presents the value of an American-Option using a trinomial model.
Input: The command-line input is the same as what I have for the C++ code that priced the European option in lesson 6 of my notes.
Output: A sample output that I expect from your code is shown in figure ??
Figure 1: Sample output (Note: 20 divisions will take some time to run on your computer. Be patient. The next part of this assignment will be able to handle a large number of divisions, as you will see.).
3 Part 2: Pricing an American-Option using a Trinomial Model by Dynamic Programming
Using my C++ program american option pricing by dynamic programming.cpp on Compass as reference, write a C++ program that takes as command-line input the values of T,N,r,σ,S0 and K, and presents the value of an AmericanOption using a trinomial model.
Input: The command-line input is the same as what I have for the C++ code that priced the European option in lesson 6 of my notes.
Output: A sample output that I expect from your code is shown in figure ??
Figure 2: Sample output (Note: A large number of Divisions should not be a problem when you use Dynamic Programming.)
