The Highly Technical Doohickey Company has released TickerMenu
(http://www.TickerMenu.com), a Mac OS X-only application that lets
you keep an eye on current stock prices by displaying them in the
your menu bar. It costs US$8.95; a demo is available for download.

Clicking on a quote reveals more information about the stock and its
trading activity, including the day’s high and low prices and trading
volume. A click of a menu item leads directly to full information
about a stock available from a variety of financial web sites.

Stock prices are updated automatically. Also, they’re color-coded to
reflect daily increases (green) or decreases (red) in price; users
may also select a greyscale display instead. Clicking on a quote in
TickerMenu reveals more information about the stock and its trading
activity, including the day’s high and low prices and trading volume.

A click of a menu item leads directly to full information about a

TickerMenu is compatible with either Mac OS X 10.4 or 10.5.

registration code may be purchased for only $8.95 USD. More
