Automated Confirmation Transaction Service - ACT

It sounds like the process an android goes through before agreeing to go out on a date. But it's actually an automated system within the NASDAQ stock market.

The automated confirmation transaction service, or ACT, is a computer program that records and reports data about settled transactions on the NASDAQ market. The goal of the system is to make the trading process more transparent.

ACT submits finished trades to the official centralized clearing system for final settlement. It also provides reports on trading activity based on the data it processes.
