If I connect NT to TD Ameritrade, I can only download 13 months plus current of historical intraday data. I.e. today, I can only download data from December 2013 up to now but not earlier than that. I know that there are available up to 24 months because that is the amount of data that can be downloaded from the TD Ameritrade StrategyDesk program.
Is there a way to change the setup of the API connection to TD Ameritrade in order to be able to download the whole 24 months?
By the way, what is the login level number used for when setting up the account connection. Which number should be used?
I know that I can download the missing data from StrategyDesk as a csv file, format it to comply with the NT template and import it through to NT but it has to be done instrument by instrument and it really would be a lot of manual work because I am planning to import hundreds.
Thank you for any advice on this.
