The Surveillance onion

The onion represents the differing levels within our suite of algorithms and how they are related.

Best execution

This is the simplest layer and creates metrics for the trade performance against standard benchmarks.

Transaction cost analysis

Our quantitative TCA has many unique proprietary metrics including market impact and information leakage.

Algorithm evaluation

This component analyses the performance of a trading algorithm given the market environment.

Liquidity Provider  ranking

We compare the relative metrics of all the venues where trades are executed to propose optimal trading allocations.

Ethical evaluation

This component has a suite of analytic tools to detect that trading occurs according to the Codes of Conduct.


The top layer in the Raidne suite contains our most sophisticated algorithms to detect market manipulation and abuse using

  1. Rules-based trading checks. 
  2. Statistical analysis to check for anomalies.
  3. Machine-learning techniques designed to reduce the number of false positives.

Quantitative Surveillance
