Nasdaq ends high-speed trading service due to complaints

Nasdaq will discontinue a high-speed trading service after regulatory scrutiny. The service, which offered select clients faster fibre optic cables for $10,000 a month, faced complaints from competitors unaware of its existence. The move follows allegations from McKay Brothers, a telecom group, claiming Nasdaq provided some clients with an unfair speed advantage. Nasdaq stated it is working with regulators and clients to end the service. This situation highlights ongoing tensions in high-frequency trading, where speed is crucial. Nasdaq is also upgrading its data center to address capacity issues and ensure fair access for all customers.
