Gateway Load

Proxy Traders

To increase the number of traders who use a TT Gateway, you can create proxy trader accounts (with the membership TTORD) and map them to direct traders.

The trader load that each TT Gateway supports depends upon network traffic, trading volume, and the numbers of connecting direct and proxy-traders. Because TT Gateway load depends upon these contextual variables, contact your TT TAM to determine an appropriate load balancing schema for your TT Trading System.

  • TT Gateways must remain online and operational during trading hours.
  • Never take down a gateway server during the trading day unless catastrophic conditions are occurring. Wait until the close of the trading day.
  • Before taking down a gateway server, be sure to download all fills for the day, if need be, using X_RISK®.
  • Before taking down a gateway server, inform all traders that they will not have access to the exchange while the TT Gateway is down.
  • When upgrading a TT Gateway, to eliminate risk, traders must close their positions; they should have no orders remaining in the market.

Market Price Feed (MPF)

One way of reducing load on your TT Gateways is to centralize your price feed onto one TT Gateway for multiple TT Gateways that connect to the same exchange. With this setup, you can continue to use multiple TT Gateways with unique exchangenames (i.e., CME-A, CME-B, CME-C, etc.), while having only one TT Gateway provide prices for all of the uniquely named TT Gateways. TT refers to this architecture as the Market Price Feed (MPF).

For further details on creating an MPF environment and centralizing an exchange’s Price Server processes onto one TT Gateway, refer to the TT document called Market Price Feed (MPF) Feature Guide.
