Autex(redirected from Autex System)
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.
An electronic network allowing broker-dealers to communicate with each other easily when they receive orders to buy or sell a large block of securities. Autex allows broker-dealers to find a better, or at least a similar, counter-offer from another broker-dealer. This allows them to transact with other broker-dealers rather than automatically sending the block to the market maker, who is obliged to fill the order if need be. Autex is less commonly called the super message.
An electronic network alerting broker-dealers to the interests of other broker-dealers in buying or selling large blocks of securities. For example, a broker may have an institutional customer interested in disposing of 100,000 shares of a stock. Rather than dumping such a large order on the exchange specialist, the broker could use the Autex system to determine whether other broker-dealers are interested in, or have customers interested in, acquiring that block of stock.
