Core Viewpoint - A significant dispute has arisen in the global high-frequency trading sector, focusing on a speed competition transitioning from milliseconds to nanoseconds, with allegations against the German Eurex exchange for allowing certain trading firms to gain a speed advantage through a controversial strategy known as "Corrupted Speculative Triggering" (CST) [1][6]. Group 1: Allegations and Complaints - French high-frequency trading firm Mosaic Finance has filed a complaint with the European Commission, accusing Eurex of facilitating unfair practices that allow a small group of companies, including Optiver, to maintain a speed advantage of approximately 3.2 nanoseconds by sending large amounts of invalid data to the exchange [6][9]. - This strategy is estimated to have generated up to €600 million (approximately $700 million) in profits for its users over the past three years, while Eurex has benefited from increased revenue by selling fast data connection services to these firms [6][9].
