Post Install – Hostinfo.cfg File Optiq

Overview

You must configure all connection information in the hostinfo.cfg file as described in the sections below.

Configuring Price Server Connection

By default, TT Gateways install pre-configured to join the correct market data multicasts for all products. However, you must add your exchange-provided credentials to connect to the Standing Data, Refresh and Retransmission servers using the procedure below.

In addition, you can perform additional configurations as described in Configuring Product Subscriptions.

To connect the Price Server:
  1. Use a text editor, such as Notepad, to open the hostinfo.cfg file.
  2. To establish the connection with the exchange Refresh and Retransmission Servers, you must set the ReplayID parameter equal to the exchange-provided source ID. You must also remove the hash (#) symbol from in front of the parameter.

    If the exchange provides additional replay IDs, you may them to the hostinfo.cfg file by adding ReplayID parameters followed by a sequential, numerical value (e.g., ReplayID1, ReplayID2, etc.)

  3. Standing data, including multicast information, is now retrieved via the Euronext File Services (EFS) mechanism rather than via FTP as in previous versions. Customer administrators should request EFS sessions via the Euronext Optiq portal at https://connect2.euronext.com
    Without access to EFS, the Price Server will not start up successfully. Gateways that will run the NYSE Liffe Price Server must have access to https://efs.euronext.com over the Internet.
    This is configured in hostinfo.cfg as follows:
    [PriceServer]
    standingdataserver=https://efs.euronext.com/
    standingdatauser=obtained from exchange
    standingdatapass=obtained from exchange
    standingdataenvironment=Production

Configuring Order and Fill Server Connections

The exchange provides two separate environments; one for Equities and a second for Financials. To accommodate this setup, TT recommends configuring at least two Order Sessions with one for each environment.

The procedure below shows the minimum configuration required to place orders and receive fills. For an explanation of advanced configurations, refer to the content beginning with Configuring Order and Fill Server Connections.

To connect the Order and Fill Servers:
  1. Use a text editor, such as Notepad, to open the hostinfo.cfg file.
  2. To establish the Order Session connection, add your credentials to the following parameters:
    • SenderCompId: Set this equal to the exchange-provided ITM you wish to use for routing through this particular Order Session. This value must be unique for each Order Session.

      Example: SenderCompId=4TD

      Note

      You must work with the exchange to properly permission the Order Session's ITM for the trading environment (Equities or Financial) set by that session's Environment parameter.
    • SenderSubId: Set this equal to the firm's member mnemonic. Multiple Order Sessions may use the same member mnemonic for the SenderSubId parameter.

      Example: SenderSubId=FRM

    • Member: Set this equal to the direct trader's Member portion of their Member, Group, Trader ID (MGT). TT Gateways use this value to route traders' orders through a particular order session. Since the exchange uses a separate environment for Financials and Equities, you can use the same Member parameter in multiple Order Sessions. This allows traders to map to a separate order session for each environment.

      Example: Member=MB1

    • PrimaryAddress: Set this equal to the exchange's Common Customer Gateway (CCG) IP address.

      Example: PrimaryAddress=10.1.2.3

    • PrimaryPort: Set this equal to the exchange's Common Customer Gateway (CCG) port assignment. The exchange may provide two separate port assignments. TT Gateways use the Binary Port provided by the exchange.

      Example: PrimaryPort=10001

    • Environment: Set this equal to the same environment permissioned for the session's ITM (Equities or Financial).

      Example: Environment=EQT

      -or-

      Example: Environment=FIN

    • Exchanges: Set this equal to the exchanges enabled for the ITM listed in the [ExchangeCodeMappings] section in the hostinfo.cfg file

      Example: Exchanges=London,Paris

  3. On servers with multiple network interface cards (NIC), you may optionally use the NetworkInterfaceFeed parameter to specify a NIC for this Order Session by removing the hash (#) symbol and entering the NIC's IP address.

    For more information on configuring multiple NICs, refer to Configuring Multiple NIC Setup.

  4. TT Gateways support multiple Order Sessions. To create additional Order Sessions, you can create a duplicate copy of the existing [OrderServerSession_X] section into the hostinfo.cfg file and assign a new, unique value for the section header and configure all parameters as described in Configuring Order Sessions.
