A proprietary, computerized trading system whose rules are not disclosed or readily accessible.
A term used to describe a trading system which has been created and back-tested by an independent supplier. Due to the problems of such systems frequently having been curve fitted, many black box systems are often not particularly robust in the long-term. Although some systems have shown good results over time, it would hardly be unfair to note that the majority have not.

In cryptography, a theoretical construct related to the most secure means for keeping documents, information, etc. secret. In such a construction, the key, or "secret", would be kept in this black box. Data to be encrypted would be put in the box, and a forgery-proof signature, or encrypted data, etc. would be returned. No information about the encrypted data would be able to be discovered by tapping the interface between the outside world and the box. In practice, however, a black box is difficult, if not impossible to construct. See ' Dark box'. _____________________________________________________________________________
