The sequence of operations is an important financial subject that has attracted the researchers' attention for many years. The quality of electronic trading platforms can be improved by validating the sequence of operations via two modes. The first one is detection and prevention of abusive behavior in the market. Surveillance systems ensure the monitoring of this parameter. The second one is verification of technical stability. Defect management is an essential part of improving software reliability by means of test tools. We propose that using data analysis and artificial intelligence can help significantly improve the quality of electronic trading.

First and foremost, it is worth reviewing a typical clearing system infrastructure: there is a number of internal components, where each one is responsible for a variety of tasks, or possibly incorporates several tasks at a time.

Having a lot of experience dealing testing such systems, the Exactpro team is used to encountering challenges on a daily basis. This paper focuses on the ones that are most prominent, and on the way Exactpro addresses them.
