Hi,

Yes, in my understanding Error 53 (BrokerAsset == 0) should only stop trading with the Asset that has problems, but continue trading with the other ones. I think that session with the broker is not completely closed (because I can see that the affected Asset re-subscribed again few minutes later), but somewhat freeze, and if one asset loose the subscription everything is stopped until that asset is subscribed again. Support and developer are looking into it.
