[amibroker] Back Fill HIstorical data

[Shweta Shalini]

Hi,

I am trying to update my data with previous years EOD files.But import 
wizard shows importing data but then doesnt show the same. My data base 
settings allows more than 30 yrs of data and i have hardly ten years of 
data.

Pls advise if back fill of data is allowed or do i need to make new 
database.
