Hello Centcel,
Glad to hear from you. If you are using JFD Demo account, then you should use the MetaTrader-Demo data source that comes by default in EA Studio. This data is coming exactly from JFD Demo. So you do not need to worry about the data at all. No need to export it and import it. It imports automatically every couple of hours and you have a huge number of bars that is just enough.
Hope that will make your day sunny :)
