What is the Intermarket Surveillance Information System (ISIS)?

The Intermarket Surveillance Information System (ISIS) is a centralized database that collects and distributes trading information from all major U.S. stock exchanges. It was developed to provide regulatory agencies with a comprehensive view of trading activities across multiple markets, facilitating the detection of potential irregularities and maintaining market integrity.

The primary purpose of ISIS is to:

• Monitor trading activities across interconnected exchanges.
• Detect unusual trading patterns that may indicate fraudulent behavior or insider trading.
• Facilitate coordination between regulatory agencies and stock exchanges for effective market surveillance.

ISIS serves as a central repository of transaction data, including trade volumes, prices, and order flows. By consolidating this information, it enables regulatory authorities to track the movement of securities and identify potential market manipulation or collusion.

How ISIS Works

ISIS operates by gathering real-time trading data from all major U.S. stock exchanges, including the New York Stock Exchange (NYSE), NASDAQ, and other regional exchanges. This data is then compiled into a centralized database that is accessible to regulatory bodies, such as the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA).

Key functions of ISIS include:

Data Collection and Integration

ISIS collects comprehensive trade data, including order types, execution times, trade volumes, and prices. It integrates this information from multiple exchanges, ensuring a complete and accurate representation of market activities.

Surveillance and Analysis

Advanced algorithms and analytics tools are used to analyze trading patterns and detect anomalies that may indicate insider trading, front-running, or other fraudulent practices.

Alert Generation and Reporting

When suspicious trading patterns are detected, ISIS generates alerts and reports them to the relevant regulatory authorities. These alerts enable regulators to investigate potential violations and take appropriate action.

Cross-Market Coordination

ISIS facilitates cross-market coordination by providing a unified view of trading activities across all participating exchanges. This helps regulators identify coordinated manipulation schemes that span multiple markets.
