Hello Wayfarer,
Glad to hear from you. If I understand you right you do not see matching trades on the two platforms, right?
The reason for that, most probably, is because you have placed the EAs on both platforms at different times.
For example, on your Demo 1 account, you have Robot A, Robot B, and Robot C.
You select Robot B and Robot C for your live account(simulated Demo 2).
When you put Robot B and Robot C on your Demo 2 account, you might still have opened trades on your Demo 1 account.
Then the EAs will start opening trades on the Demo 2 account and they will be different (because you placed the EAs later in time).
Then the EAs in the first account may close the trades, and open new ones while the positions from the same EAs are still open in Demo 2.
That might continue for a while before the 2 accounts are syncronize. From our experience, it might take up to a month or even longer.
