PFX Market Data

Overview

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.

Enabling PFX

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.

The following is a list of the minimum client application versions that support the PFX wire format. You need to upgrade to these versions in order to support PFX in your trading environment.

Note

To achieve optimal performance and reliability, TT recommends that you install the most current production release available for each of the products listed in this section.
