Dear support,

if there are 2 logins to one account at the same time, IMessages will be sent to all clients.
What happens, if an order-IMessage can successfuly get delivered to client A, but - e.g. due to temporary problems with the internet connection - not to the other client B?

How does DukasCopy handle this situation:
a) Will client B still receive the message when the connection is up again?

b) Or are there chances that client B will lose out this message?

c) For how long will messages that cannot be sent, be queued at DukasCopy? Is there a timeout period?

d) What happens if a message cannot get delivered to any of the clients (within a timeout period)?

e) Is there a way to retrieve historic messages?

Thanks a lot for your feedback!
Best regards, RR.

all messages during dosconnect are lost. After client reconnects we do synchronize order lists and for any changes in orders send IMessage with correct type for the change.

There is no way to retrive historical IMessages

ok, I think I understand. Just to go sure:
The synchronize check is performed for each client independantly of each other.

Example:
client1 logged on to account xyz stays connected and receives all messages for period1
client2 logged on to same account xyz gets disconnected in period1. After client2 connects again it will receive all change-messages from its very own synchronize-change-check against the order list on the server?

Is that correct?

Thanks, RR.

Yes, that's correct
