ICE Gateway

Configuring the Trading Environment

Load Balancing

As a guideline, TT recommends that no more than 20 direct traders connect to ICE Gateway through any one ICE Gateway.

Note

Due to the variety of factors involved (e.g., hardware specifications, trade volume, etc.), you should work with your Technical Account Manager to determine your optimal load-balancing solution.

MPF2 Setup

Using MPF2, you can configure one TT Gateway to provide prices to client applications and additional TT Gateways for orders and fills. The following diagram illustrates a standalone Price Proxy setup to support multiple Exchange-Flavors of the same market. In this diagram:

  • X_TRADER® workstations connect to the appropriate mapped TT Gateway (i.e., ICE-A or ICE-B Gateway) for Order and Fill API connections.
  • X_TRADER® workstations connect to Price Proxy for all ICE-A and ICE-B Price API connections.
  • Dedicated Price Proxy routes price subscriptions and resynch requests to the MPF server (named ICE-Z) for ICE prices.

TT supports both single instance and multiple instance Price Proxy standalone servers. Each setup utilizes similar network topology as described above.

For complete information related to possible MPF2 Configurations, refer to the MPF2 Feature Guide.

Configuring the NIC Setup

TT recommends using a dual-NIC (network interface card) setup for all ICE Gateways. This includes:

  • One NIC facing the customer’s local network
  • One NIC facing the ICE Network

Configuring Price Server Failover

You can set up a secondary Price Server to continue to receive price updates in the event the Price Server becomes inactive. When properly configured, Price Server failover occurs seamlessly.

To configure Price Server Failover

  1. Run the ICE Gateway installation on that particular machine.

    You must ensure that both machines use the same Exchange-Flavor and share the same multicast. In addition, you should configure the [PriceServer] sections in the hostinfo.cfg file on both machines with the same values.

  2. In the ttchron.ini file, comment out the Order Server and Fill Server sections.
  3. Once properly configured, prices continue to update even if the primary Price Server goes down.

Configuring Order Server Failover

Due to limitations from the ICE Host, ICE Gateways Version 7.3 and higher no longer support Order Server failover. If the TT Gateway experiences an Order Server disconnect, the Exchange places all working orders in an Inactive state. These orders appear as Hold in the X_TRADER® Order Book and Inactive in WebICE.
