Understanding the Price Feed
PFX Price Support
BrokerTec Gateways Version 7.12 and higher support TT’s PFX price delivery architecture.
TT Gateways and client applications utilize the PFX price delivery architecture. PFX improves the reliability and scalability of delivering prices to the client trading applications. PFX also maximizes price scalability and bandwidth utilization under peak network load while maintaining extremely high performance.
The TT Gateway can be enabled to deliver PFX price updates by configuring the PFXEnabled parameter in the aconfig.xml file using the Aconfig Utility. After a new installation or upgrade to a PFX-capable TT Gateway version, the parameter can be configured as part of the PFX migration procedure. By default, the TT Gateway installs with PFX disabled (PFXEnabled=false). Please contact your Technical Account Manager to switch the Gateway from PFX-disabled to PFX-enabled or vice versa.
For more information regarding PFX architecture and migration, refer to the TT Gateway Architecture System Administration Manual.
