When installing one NFX Gateway in your environment, you must configure and un-comment the Key Server section in the ttchron.ini file.


You can only run a maximum of one Key Server per market; if another NFX Gateway is running a Key Server in this TT environment, do not uncomment the Key Server section.

In addition, all users should check the start/stop times for all services.


You must perform the following in the ttclean.ini file:

  • Verify the following lines have been uncommented and have the appropriate drive letters assigned:

    P, 10, c:TTAuditfiles, *.*

    P, 10, c:TTLogfiles, *.*

  • Delete all other gateway sections.

Trader IDs

You must add trader IDs to the TT Universal Login Server (via X_RISK® located on a different machine within the TT environment) or to the Windows User Authentication System (WUAS) Active Directory.


Reboot the server.

TT User Setup Restart

TT User Setup Servers must be restarted after adding a NFX Gateway to your trading environment. Failure to do so may result in missing updates to the aconfig.xml file.

This affects the first installation of a NFX Gateway in your trading environment. Subsequent NFX Gateway installations do not require a TT User Setup Server restart.

Start TT Services

After reboot, open the Control Panel and select Administrative Tools. On the Administrative Tools menu, select Services. Double-click on the Start Guardian icon from the desktop.

Verify that the IP address that this Gateway has been licensed for appears in the Applications On section of Guardian. Start the GuardServer service, and ensure GuardServer shows up under the correct NFX Gateway Exchange-Flavor.


If the GuardServer shows up under the “TT GuardServers starting up” exchange, it has not found a valid license.

Start TTChron

Start the TTChron Service in order to start all necessary TT Services, (assuming you are starting the NFX Gateway during normal trading hours).

Execute Test Trade

Once the NFX Gateway is completely green in Guardian, log in to an X_TRADER® machine and enter a test trade. Risk parameters must be set up in order to successfully place a trade.
