I've coded up a Strategy that (in theory) checks the timestamps from the exchange and compares it to your PC time. If they are out of whack more then 3 seconds, you get an alert.
This comes from some ideas I've been reading about regarding last weeks events.
If you think this might be useful, I'd love to hear how to make it even more useful.
NT7b15 compile.
I'd suggest launching it via the Strategies tab in Control Center, using ES 1 second as the dataseries and just let it run in the background. Things you can change via the New Strategy dialog are:
DelayThreshold: defaults to 3 secs
LogAlerts: defaults to TRUE. Error-level log alert.
PrintDelay: Prints the delay between your PC and the incoming ticks in the Output window. Defaults to FALSE but worth looking at.
