ESQuotes

ESQuotes is a powerful Microsoft Excel workbook and Dynamic Link Library (DLL) for stocks and mutual funds.

Stock quotes are retrieved direct from Internet without downloading.
ESQuotes dynamically updates stock market price, change, volume, high/low, etc. from the internet! Excel provides the framework for managing your own personal portfolio of stocks and mutual funds. ESQuotes' easy to use interface allows you to watch prices, changes, volume (and more) with simple "=functions()" you already understand.
ESQuotes is not just a Microsoft Excel workbook. It combines a powerful custom DLL (Dynamic Link Library) which communicates directly to popular internet stock quote servers and gets your stock quotes from internet without having to download separate files and then having to import them. ESQuotes dynamically updates stock market price, change, volume, high/low, etc. instantly! Registered users get them in real time!
ESQuotes is your electronic counter measure and works through corporate firewalls using normal http protocol and ports. This simply means that ESQuotes looks like an ordinary browser by your computer, so ESQuotes can't be blocked without blocking all browsers. ESQuotes will hardly be noticed by the IS Police because it opens and closes the internet connection in less than 1 second for each batch of quotes. Multiple stock quotes are efficiently sent to the stock quote server.
This keeps your Internet activity so minimal that the corporate internet police should never notice it at all, even if you quote every minute all day! While at work, ESQuotes quietly blends in with its surroundings, looking like an ordinary Microsoft Excel spreadsheet. HA!
No one will know that you're keeping track of your stocks (that is unless you tell them)! ESQuotes is quite happy at home over a dialup connection, since it needs nearly zero bandwidth! This means that slow modem connections won't matter.
