High Volume Service


The High Volume Service (HVS) is a specialised testing service providing an environment in which our customers can test that their infrastructure supports market data delivered at peak throughput, without dropping messages.

This service ensures customer's systems are fully compatible with Exchange, and ensures that information delivery is supported in a high capacity environment.

This dynamic service broadcasts live data at a maximum rate across the broadcast services to which a customer subscribes.

High Volume Test sessions must be pre-booked and last approximately 120 minutes.
