Exchange Host Failure and Recovery

Overview

In the unlikely event that the actual exchange host fails, all electronic traders on that exchange lose their connections.

Connection Failure

If the exchange host fails, traders experience the following:

  • Orders actions in transit before the failure are lost.
  • The TT LME Gateway Order and Price Servers begin cycling (starting up and shutting down according to the schedule set in ttchron.ini).
  • All price, order, and fill data becomes stale.
  • Traders lose their connections and cannot trade.

Connection Recovery

When the exchange host recovers, the following occurs:

  • If set to run in ttchron.ini, the TT LME Gateway server components (Price, Order) reconnect to LME.
  • The TT LME Gateway re-request all fill and order information from the exchange. No information is lost.
