Option: Option is a contract that gives the buyer the right, but not the obligation, to buy or sell a specified quantity of a commodity or other instrument at a specific price within a specified period of time, regardless of the market price of that instrument. There are two types of options: Put Options and Call Options.
Option Pricing Model: Option Pricing Model is a mathematical model used to calculate the theoretical value of an option. Inputs to option pricing models typically include the price of the underlying instrument, the option strike price, the time remaining till the expiration date, the volatility of the underlying instrument, and the risk-free interest rate (e.g., the Treasury bill interest rate). Examples of option pricing models include Black-Scholes and Cox-Ross-Rubinstein.
