Configuring user access to MEFF

To configure user access to MEFF:

  1. Click the Users | Exchanges tab for a user selected in the data grid.
  2. Click the exchange list drop down arrow, and scroll to and select an exchange.
  3. Click the Subscriber Market Data, FIX Market Data and Order Routing tabs to configure the user for the selected exchange:

    • Use the Subscriber Market Data tab to allow or deny the user access to all market data per product group.
    • Use the Order Routing tab to configure exchange credentials for user identification.
    • Use the FIX Market Data tab to allow or deny the user access to all market data through TT FIX per product group.
  4. Configure the following Order Routing settings:

    • Sender Sub ID: Identifies the user on all order actions. This value maps to the Tag 50 field in the exchange API. Enter the exchange-provided Sender Sub ID value.
    • Text 1 — An optional, user-defined text value that remains on submitted orders in the TT system but is sent to the exchange as Tag 58. Enter up to 15 characters. Alpha-numeric and special characters are allowed.
    • Text B — An optional, user-defined text value that remains on submitted orders in the TT system. If entered, this value is sent as Tag 1 instead of the Clearing Account value. Alpha-numeric and special characters are allowed.
    • Text TT — An optional, user-defined text value that remains on submitted orders in the TT system, but is not sent to the exchange. Alpha-numeric and special characters are allowed.
    • SMP ID — Sets the self-match prevention (SMP) identifier for using the MEFF self-execution prevention service. If an SMP ID is entered in this field for a user, then any orders submitted by other users with the same SMP ID are rejected by the exchange. Enter a three-digit numeric value of 0—999. This is an optional field.
    • Max Order Rate — Sets the maximum number of orders per second that a user can enter per connection. This limit cannot exceed the exchange-defined order rate maximum.
  5. Click the Subscriber Market Data tab to allow or deny access to All Market Data available at the exchange.

    If Allow is enabled, click Sessions to set how many simultaneous market data sessions the user can have active using different IP Addresses/Applications. Selecting 0 - Delay Only indicates that the product group is denied in all environments except the delayed environment, which does not have access to real-time market data.
  6. Click the FIX Market Data tab to allow or deny FIX Users access to All Market Data available at the exchange.

    If Allow is enabled, click FIX Users to set how many simultaneous market data sessions the user can have active using different FIX Users. Selecting 0 indicates FIX users can access only security definitions and security status updates for the product group.
  7. Click Save Changes.
