I have downloaded a bunch of historical data (day, minutes) of an instrument, within an specific year-month expiration. For example: EMD 12-20
After this instrument rolls over, and a new expiration date comes up (in this case EMD 01-21), my chart is not able to load historical data anymore, unless I come back and select EMD 12-20.
Is there any option to migrate the historical data from an expirated instrument (EMD 12-20) to the new one (EMD 01-21)?
I have found an easy way: to change the name of the folders in C:\Users\...\Documents\NinjaTrader 8\db\day\EMD XX-XX (where XX-XX is the new instrument name).
And the same for the folder C:\Users\...\Documents\NinjaTrader 8\db\minute\EMD XX-XX
But I don't know if changing that would produce any unwanted effect over NinjaTrader database.
Thanks a lot!!
