Insider Trading Alert System

What Is This?

This site was the winning entry in Yahoo's web programming competition in 2009. It is a near real-time parser of the SEC's EDGAR database. You can search for a company to see insider transactions and sign up for email alerts. Email alerts are sent out within ~15 seconds of the information becoming public, making this far more current than Google Finance or Yahoo Finance.
