In finance, the binomial options pricing model (BOPM) provides a generalizable numerical method for the valuation of options. The binomial model was first proposed by Cox, Ross and Rubinstein in 1979.[1] Essentially, the model uses a “discrete-time” (lattice based) model of the varying price over time of the underlying financial instrument. In general, Georgiadis showed that binomial options pricing models do not have closed-form solutions.
