Failover to a backup watchdog machine

[Hyper]

Most recently I was in the MetaTrader Forex world, in which unlimited connections can
be made to the server. So a "watchdog" system on a different dedicated machine
could be constantly available to take over the primary system.

However, in Futures, connections are very restrictive. I've got NinjaTrader with the Rithmic
Order routing and Market Data; and I'm looking for advice on a failover system. These
are dedicated servers in a data center; so are as reliable as possible.

I could have the secondary system monitor a reliability signal; and in the event of failure,
cause the primary NinjaTrader instance to be killed; and immediately spawn a copy which
could resume processing on the failover system -- somehow. The "one and only one
connection" approach...

Would a good approach be to somehow purchase the right to have 2 Globex futures
connections into the same account, so that the failover could be a "hot monitor" of the primary?

Just looking for advice, both technical and brokerage related. There must be a subset
of traders doing full automation, so if anybody can give me some ideas, I'd appreciate
it. THANKS IN ADVANCE.

Hello Hyper,

Thank you for your post.

The CME assesses market data fees per individual platform. This is why you can only connect to your account data feed from one platform at a time.

If you would like to connect to your account from two machines at the same time, then you would need a second market data connection for your brokerage account. You can contact your broker directly to see if it would be possible to request a second market data feed so you can access your account from two separate computers at the same time.

Let me know if I may be of further assistance.
