The Evolution of Trade Surveillance in Financial Markets

In financial markets, trade surveillance is the process of monitoring trading activity for suspicious activity. It’s a crucial tool in protecting all market participants, but it can also complicate regulatory compliance. For this reason and more, financial institutions must understand the requirements of trade surveillance and enforcement trends to avoid potential violations.

Here’s everything you need to know about navigating trade surveillance.

Understanding ASIC Trade Surveillance

In trade surveillance, regulators, Market Participants (i.e. members of an exchange) and other licence holders monitor trade data including trading patterns to identify various types of market misconduct — for example, insider trading or market manipulation. The main goal is to uphold market integrity and protect participants, including investors and consumers. 

In Australia, the main authority responsible for oversight of markets and related trading activity is the Australian Securities and Investments Commission (ASIC). It uses a sophisticated trade surveillance system to automatically detect potential market misconduct and suspicious trading patterns. The system can also identify where participants may be getting inside information.

To do this, ASIC’s system analyses trading activity and other data from multiple sources, including its own databases, the Australian Securities Exchange (ASX), other securities exchanges and the Australian Taxation Office (ATO). ASIC searches through information such as:

• Order******


• Origin of order******


• Trade executions.tivi


• End-of-day summaries.


• Over-the-counter (OTC) market transactions and reference******

As the ASIC surveillance teams and systems parse through the data, they look for patterns that could indicate suspicious trading activity. This may include predefined risk indicators or “red flags” including behaviours such as:

• Large order executions and/or deletions.


• High order-to-trade ratios.


• Stock pumps or dumps.


• Predatory high-frequency strategies.


• Layering and spoofing.


• Unusual quote/order price movements.

If ASIC suspects market misconduct, it will reach out to the market participant in the first instance to make enquiries into the behaviour. It also requires Market Participants to have appropriate surveillance arrangements of their own, which may lead to suspicious activity reports (SARs) — required to be submitted to ASIC by Market Participants under the Market Integrity Rules (MIRs ) — as a trigger to conduct further investigations or thematic reviews. It also monitors for overall compliance with its MIRs.

Your Responsibilities
