Clarification on MarketData.GetBars

Hi Panagiotis,

I'm just a little bit confused and wanted to clarify if this is a bug or a feature:

When using MarketData.GetBars in a cBot to fetch historical bar data I sometimes get the exception "cTrader.Automate.Small.V1.Exceptions.AlgoAbortedException". But when iterating through the bars it seems that even so all data is available.

Is this the nornmal behavior - e. g. when bar data was not changed in the meantime - or is there anything to be done to "reset" the connection to get the actual data?
Or could this be based on the garbage collector and classes using this function need to implement the IDisposable interface and manually "dispose" the bars object?

Thanks in advance and best regards,
Christian
