Market Surveillance Systems
Market surveillance systems are specialized technology platforms that monitor trading activities across financial markets to detect potential market manipulation, insider trading, and other forms of market abuse. These systems analyze real-time and historical data to identify suspicious patterns and ensure market integrity while helping firms maintain regulatory compliance.
Core functions of market surveillance systems
Market surveillance systems perform several critical functions in modern financial markets:
-
Pattern Detection: Monitors trading patterns to identify potential market manipulation such as spoofing, layering, and front running.
-
Alert Generation: Creates real-time alerts when suspicious activity is detected, allowing compliance teams to investigate potential violations quickly.
-
Case Management: Provides tools for investigating alerts, documenting findings, and managing the regulatory reporting process.
Next generation time-series database
QuestDB is an open-source time-series database optimized for market and heavy industry data. Built from scratch in Java and C++, it offers high-throughput ingestion and fast SQL queries with time-series extensions.
Real-time monitoring capabilities
Modern surveillance systems process massive amounts of real-time market data to detect potential violations as they occur:
- Order flow analysis
- Price movement monitoring
- Volume analysis
- Cross-market surveillance
- Cross-asset correlation analysis
These systems must handle high-throughput data processing while maintaining low latency to be effective in today's high-speed markets.

Advanced analytics and machine learning
Modern surveillance platforms increasingly incorporate sophisticated analytics:
- Behavioral analysis
- Network analysis for detecting coordinated trading
- Anomaly detection using machine learning
- Natural language processing for communications surveillance
- Pattern recognition across multiple time scales
Regulatory requirements and compliance
Market surveillance systems help firms meet various regulatory requirements:
- Market Abuse Regulation (MAR)
- MiFID II transaction reporting
- Dodd-Frank Act compliance
- SEC Rule 15c3-5 (Market Access Rule)
The systems must maintain detailed audit trails and support regulatory reporting automation to demonstrate compliance with these requirements.
Integration with trading infrastructure
Surveillance systems integrate with multiple components of the trading infrastructure:
- Order Management Systems (OMS)
- Execution Management Systems (EMS)
- Market data feeds
- Trade reporting systems
- Risk management systems
This integration enables comprehensive monitoring across the entire trading lifecycle.
Performance considerations
Key performance requirements include:
- Low latency processing
- High throughput capacity
- Scalability for market data volume
