@luxiangyuan

You can find field definition for any field from file RDMFieldDictionary locates under a folder named "etc" from EMA package. REF_Count use UInt64 according to the Dict so that you have to use fe.getUint() to get the data accordingly.

Consumer example such as 200__MarketPrice__Streaming also provide sample codes to get the data accroding to data type returned by fe.getLoadType().
