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.
