Definition of Autex
Video communication network through which brokerage houses alert institutional investors of their desire to transact block business (a purchase or sale) in a given security. Indications transmit small, medium, and large sizes only, with occasional limits mentioned. Supers are messages with specific size and price included. Both "indications" and "supers" can be only seen by customers (institutional subscribers to Autex). Trade recaps, advertised block trades entered by the dealer/subscribers, are also displayed, but can be seen by both institutions and dealers. See: Expunge, size.
