OptionGrid is a financial data-mining application designed to research, screen, and compare covered call option positions. OptionGrid downloads free, 20-minute delayed quote data from the Internet, and it performs a variety of calculations using that data, including annualized returns and downside protection. OptionGrid provides powerful filtering and sorting capabilities to locate the best possible covered call positions from a portfolio of stocks. Additionally, the software calculates potential returns using an investor's own cost basis and share counts in a stock. Other features include quick data export to applications like Microsoft Excel and integrated access to 3rd party websites for information like charts, news, and analysis.
