Thanks @AndrewAMD, @hast29!

In both these scenarios, no real trades are being done, so the broker connection is only being used to get prices. Since for this use case prices are available without a broker connection (as Test does), this begs the question: Is there a way to easily create a "Phantom" broker plug-in that gets prices as in Test and then just returns success for all "Trades"? I seem to recall some other thread where someone had (easily?) done at least the latter...
