Support for Market Depth and PFX Market Data
The GMEX Gateway receives detailed market depth directly from the exchange, and forwards it to the client applications. This is not configurable on the gateway.The maximum number of depth levels can be restricted by a client application. However, X_TRADER currently supports a up to 20 levels of market depth and can display the maximum levels of depth provided by the gateway.
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 enabled (PFXEnabled=true). Please contact your Technical Account Manager to switch modes on the Gateway.
