EXPO & EXPO/SE (Leading Market Technologies)
This company's products are often used for analysis in the
financial industry. "It's flagship product EXPO has a powerful
backbone of mathematical, statistical, and time series analysis
routines, paired with a highly visual, customizable, easy-access
front-end." They also offer a high speed server. Many of their
products can be downloaded for a free trial. They also offer a
free student version. It is a subset of the regular version in
only two ways: it supports only 12 open windows, and it cannot
perform realtime analysis.
