Over the past month messages as the following have appeared when trading at Oanda:

Code
!Gateway Timeout. 
!Gateway Timeout. 
!Gateway Timeout. 
!Gateway Timeout. 
!Gateway Timeout. 
!Gateway Timeout. 
!Trade not open - xxxx
!Result: {"errorMessage":"Gateway Timeout."}


My recollection is that anything starting with "!" is a message from the Broker, not Zorro, which would mean that both "Gateway Timeout." and "Trade not open - xxxx" came from Oanda (or Oanda's API).

Is this understanding correct?

Also, would Black Box Recording (BBR) provide more information that Oanda could find helpful in resolving this? Is it worth running in BBR for some time?

Thanks.
