The Trinomial tree is a similar model, allowing for an up, down or stable path. The OIS is chosen here as it reflects the rate for overnight unsecured lending between banks, and is thus considered a good indicator of the interbank credit markets. The binomial pricing model traces the evolution of option pricing model option's key underlying variables in discrete-time.

Articles lacking sources from September All option pricing model lacking sources. For a call optionthe option is in-the-money if the underlying spot price is higher than the strike price; then the intrinsic value is the underlying price minus the strike price.

Being relatively simple, the model is readily implementable in computer software including a spreadsheet. Relatedly, this risk option pricing model value is then adjusted for the impact of counterparty credit risk via a credit valuation adjustmentor CVA, as well as various other X-Value Adjustments which may also be appended. If exercise is permitted at the node, then the model takes the greater option pricing model binomial and exercise value at the node.
