I've never dabbled in the financial markets although if I did, I'd probably use something like QuoteTracker to keep track of the latest stock market fluctuations and movements.

QuoteTracker links into various datafeeds, brokers and financial sites to provide you with real-time quotes, live intraday charts and quotes according to what stocks you need to track. If you're brave enough, you can even upgrade to allow a professional trader to use your stocks using the QuoteTracker interface. The program can be used to track most kind of stocks - from securities to stocks, options, indices, futures, FOREX/currencies, bonds and more. Be warned however - if you don't have any idea about stocks and shares then this is a hugely complicated program. The main interface is simply a mess of numbers and graphs that won't really mean anything to you unless you have some experience of the stock market. In which case, be very careful before upgrading and allowing a real broker to deal with your money. If the developers had actually provided more user info and instructions as how to use the program and understand stock markets, it would have been a lot more useful.

If you know what the stock markets are all about, and are not intimidated by huge numbers of rapidly changing figures and graphs, then you may find some use for QuoteTracker.
