An option chain is a comprehensive list that shows you all available option contracts for a given stock. These are sorted by their expiration date, which is the last day you can trade or use the option, and strike price, which is the price at which you can buy (call) or sell (put) the stock.
An option chain is a valuable tool for traders who want to make informed decisions about their investments. It provides information on the strike price, expiration date, and the price of each option.
