Method
The binomial pricing model traces the evolution of the option's key underlying variables in discrete-time. This is done by means of a binomial lattice (tree), for a number of time steps between the valuation and expiration dates. Each node in the lattice represents a possible price of the underlying at a given point in time.
Valuation is performed iteratively, starting at each of the final nodes (those that may be reached at the time of expiration), and then working backwards through the tree towards the first node (valuation date). The value computed at each stage is the value of the option at that point in time.
Option valuation using this method is, as described, a three-step process:
- price tree generation,
- calculation of option value at each final node,
- sequential calculation of the option value at each preceding node.

Famous quotes containing the word method:
“in the absence of feet, “a method of conclusions”;
“a knowledge of principles,”
in the curious phenomenon of your occipital horn.”
—Marianne Moore (1887–1972)
“In child rearing it would unquestionably be easier if a child were to do something because we say so. The authoritarian method does expedite things, but it does not produce independent functioning. If a child has not mastered the underlying principles of human interactions and merely conforms out of coercion or conditioning, he has no tools to use, no resources to apply in the next situation that confronts him.”
—Elaine Heffner (20th century)
“I do not know a method of drawing up an indictment against a whole people.”
—Edmund Burke (1729–1797)
