Hi,
I have had a similar issue, trying to download US30 hourly data which MT4 only limits to like 2000 data points (i.e. back to the end of January).
I would like to backtest further and I've followed the video Caseynotes posted and managed to get data in a spreadsheet for 10000 data point, however I am not sure whether the format is compatible with MT4 in order to import it, as when I load the CSV file in the import section in the history centre nothing comes up.
Is there something I am missing?
Thanks!
