DEFINITION of 'Expunge'

An action that destroys any record of an AUTEX indication. Expunging an indication will permanently remove an trace of a trader's advertisement for a block order.


Canceling an AUTEX indication will prevent the notice from being displayed. Once removed, the indication still remains on the historical records. This may not be desirable for some traders, who want no permanent record of their desire to buy or sell a large volume of stock. Expunging the indication will remove it from the display and prevent it from being stored in historical data.
