## How many steps are in a binomial tree?

A simplified example of a binomial tree has only one step. Assume there is a stock that is priced at $100 per share. In one month, the price of this stock will go up by $10 or go down by $10, creating this situation: Stock price = $100.

#### How many nodes are there in a binomial tree?

In our example, the binomial tree is a recombining tree, meaning that at each period N, there will be N+1 nodes. This means in our program, we’ll at least need 2 arrays of size ( N + 1 ) x ( N + 1 ) to store the stock price and the call option price evolutions, although we’ll only use the upper triangle of the arrays.
