Hi Carot
For some reason I can't post a reply to you in that other thread.
It must have something to do with the DataAvailable property. The DataAvailable property is a ushort type (if memory serves correct) so it shouldn't matter what order you add the field enumerators together.
However are there limitations to what sets of fields you can enter? E.g. High, Low, Close, Vol and Date or Close, Vol, Date.
Was the MDK MSFL manual any help? It should give a description of the DataAvailable property and any limitations.
Regards
Craig
