I purchased historical files of 2003-2020, from a third party, and I've been able to import them to Ninja Trader for 2005-2020. However, Ninja Trader refuses to import the 2003 and 2004 data files, stating the followings:
"Unable to import '....\ES 03-03.Last.txt'. Instrument is not supported by repository"
Could you please tell me why the 2003 and 2004 instruments are not supported? Please see attached error message in log
By the way, when I changed the filename 'ES 03-03.Last.txt' to 'ES 03-05.Last.txt', Ninja Trader was able to successfully import the data, and I confirmed that the data imported were 2003 data in the "Historical Data" Tool. So, the data files themselves should not be a problem but rather it seems like Ninja Trader doesn't accept data older than 2005?
Thanks,
Ben (lorien)
