Nasdaq Automated Confirmation Transaction (ACT) System

The Nasdaq ACT system supported trade reporting, confirmation, and clearing workflows for Nasdaq securities transactions.

The Nasdaq Automated Confirmation Transaction (ACT) System is a platform utilized for the reporting, processing, and clearing of trades involving Nasdaq-listed securities. It serves as a critical infrastructure within the Nasdaq stock market, ensuring that trade executions are accurately reported, confirmed, and communicated to relevant parties.

Definition

The ACT System is designed to handle several key functions:

  • Trade Reporting: Market participants use the ACT System to report trade executions. This includes the time, price, and quantity of the securities traded.
  • Trade Comparison: The system matches trade reports from both the buyer and seller to ensure the details are consistent.
  • Trade Verification: It verifies the reported trades to ensure compliance with market regulations and standards.
  • Trade Clearance and Settlement: Following the verification process, the system facilitates the clearance and settlement of trades.

How ACT Works

The workflow of the ACT System can be summarized as follows:

  • Reporting: Once a trade is executed, both the seller and buyer report the details to the ACT System.
  • Comparison and Matching: The ACT System compares the trade details submitted by both parties. If the information matches, the trade is confirmed.
  • Verification: The trade details are verified for accuracy and regulatory compliance.
  • Clearing and Settlement: After verification, the trade moves to the clearing process, where the transfer of securities and funds between the buyer and seller is processed.

Applicability

The ACT System is crucial for maintaining the integrity and transparency of the Nasdaq trading environment. It:

  • Reduces the risk of mismatched trades through automated comparison and verification.
  • Ensures regulatory compliance of reported trades.
  • Facilitates timely and accurate clearing and settlement of trades.
