After you’ve gathered all the info and invested the family fortune in a variety of stocks, you’ll certainly want to watch your money grow. The Stock Trace a Java applet created by a student at the University of Virginia, allows you to enter a stock symbol and watch a frequently updated graph that represents the price movements.
The applet allows you to put in the stock symbol you want to graph and to set a ceiling and floor limit for the stock. The applet will then notify you when either of those is reached so you will know when to buy or sell, according to your needs. (Note that price quotes are delayed by 15 minutes as required by the exchanges.)
