How to Build an Effective Modern Trade Surveillance System

“Modern trade surveillance isn’t about generating more alerts. It’s about delivering smarter insights, stronger defensibility, and a more resilient compliance framework. That’s what being truly effective looks like today.”

Carlo di Florio, President, ACA Group

As markets grow more complex and regulatory expectations continue to intensify, firms need trade surveillance solutions that do far more than generate trade-based alerts. They need technology that provides breadth, depth, and real context. A modern surveillance program must be flexible, data-rich, and built to evolve.

Enable Self-Service Calibration and Scenario Testing

Regulators increasingly expect firms to stress-test and recalibrate their surveillance algorithms on a regular basis. Without the right tools, the process can be manual, time-consuming, and difficult to audit.

ACA Group’s Market Abuse Surveillance (MAS) solution eliminates friction with our newly released Backtesting and Scenario Analysis toolset. Built-in scenario analysis and calibration tools let teams test thresholds, adjust parameters, and document the decision-making process all within the application, including a complete automated audit trail. This makes calibration practical, repeatable, defensible, and, more importantly, a key part of a successful GRC process.

Provide Broader Context Within Alerts

Like any good mystery, trading behavior alone rarely tells the whole story. Real insight comes from understanding the environment in which that trade occurred, including market events, breaking news, internal communications, and other relevant factors. Context transforms an alert from a data point into a narrative.

Through built-in data integrations and connectivity with other ComplianceAlpha® modules, ACA’s MAS solution enriches alerts with market events, news, employee trading and internal communications context, helping analysts make faster, more accurate assessments.

Integrate Data Across Your Entire Firm

Many firms operate across multiple offices, affiliates, and trading desks.  Within each often comes its own data ecosystem: separate order management systems, data vendors, reporting systems, or execution venues. A surveillance program that examines only one system or feed risks missing the full picture.

ACA’s MAS solution is designed for true data unification, integrating and normalizing information across systems, entities, and asset classes. That level of integration gives analysts the context they need to detect patterns that would otherwise stay hidden.

Focus on Analyst Workflow and Efficiency

Surveillance teams need tools that streamline analysis, not create more work. A strong program prioritizes workflow efficiency, reduces false positives, centralizes case management, and enables analysts to move quickly from detection to resolution. ACA’s MAS solution is built with this user-centric design in mind.

Intelligently-Applied AI

AI can completely transform a GRC program, but only when leveraged correctly.  AI should be treated like any other area of compliance testing; regulators want transparent and explainable protocols, not a “black box”.  The best tools are those that enhance human judgment, not those that replace it.

At ACA, we’re committed to building AI solutions that reduce the complexities of surveillance alert investigations, with a human-in-the-loop approach throughout the process to give the final say on what’s truly important.

Technology Backed by Deep Regulatory Expertise

Technology matters, but so does experience. ACA’s MAS solution is powered by insights from our world-class consulting team, which includes over 150 former regulators and in-house chief compliance officers. They work with over 6,000 clients annually to build robust and efficient GRC programs.

This expertise is embedded throughout ComplianceAlpha® and ACA, helping firms align with evolving regulatory expectations and strengthen their overall surveillance posture.
