Single Gateway Failure
The user should confirm with MEFF that in the event the customer has only one MEFF Gateway, and it fails, the exchange places all traders' orders into an inactive state.
When a single MEFF Gateway fails during trading hours all orders are canceled at the exchange. Traders stop receiving data (prices, fills, order data) from the MEFF Gateway until reconnection.
Gateway Software Recovery
After a failure, TTChron restarts any components scheduled to be running. After a successful restart of the gateway, the following activities occur:
- Fills: From the exchange, the MEFF Gateway requests and downloads all successful fills. The MEFF Gateway does not download any fill information that has already been received from the exchange.
- Orders: Upon reconnect, traders’ can resume trading and the traders’ Order Book repopulates to reflect current order status.
Gateway Hardware Recovery
If you do not recover your MEFF Gateway the same day as the failure, all fills from that day are lost.
Example Scenario - No Failover
Quick Financial Services (QFS) has one MEFF Gateway. During trading hours, their gateway experiences a drive head crash, and immediately, all traders lose their connection to the exchange. The exchange displays red in Guardian, prices stop updating, and no new fills are received. Even though they have X_TRADER® open, traders lose the ability to trade on MEFF.
QFS installs and starts up another MEFF Gateway that same day using the same configuration as the failed TT Gateway. When it connects to the exchange, it downloads all of the day’s fills and any working orders for all traders configured in its hostinfo.cfg file. Traders can log back into the exchange and begin trading at current prices. No fill or order data is lost.
