Abstract

An apparatus and method for monitoring financial securities markets or financial securities to provide information regarding the status of the financial securities markets or securities. The apparatus transforms measured values of more than one parameter of the system using a function dependent on at least baseline and critical values of the parameters. In a preferred form, the function is a sigmoid function. The apparatus further maps the function to a sequence of reference values and generating a deviation indicator for each parameter. The deviation indicators are then analyzed to generate and display information concerning the status of the financial securities markets or financial securities.
