Hi I want to share my desktop application that I've been using for day trading for over 2 years now. This was personal project, but I've decided to make it public and 100% free.
It keeps real-time connection to the exchanges and instantly notifies about significant price changes within small time periods (5m, 30m). You can find more details at the website.
