For those of you who are either hardcore traders or if you just like to dabble in the stock market, keeping up with the current price of both your portfolio as well as your watch list is essential to decision making. If you are looking for a tool which may help, give the open source project JStock a look.

JStock is a free stock market software for 23 countries. It provides Real-Time stock info, Intraday stock price snapshot, Stock indicator editor, Stock indicator scanner, Portfolio management and Market chit chat features. Free SMS/email alert supported[.]

JStock boasts a pretty impressive feature list. I can see the alerts (email/text/tray) being especially useful. Additionally, it is built on Java, so it runs on any OS.
