Not possible unless
a) your data file has negative values
b) your values exceed 32 bit integer size (about 2 billion).
This does happen with volume as noted by Jim due to back-adjusted
volumes getting huge. I suppose back-adjusted prices can go negative
too, depending on the back adjusting method used, but this would not be
the occasional value as you mention.

Subject: [amibroker] importing data using the import wizard
Hi, I have been using the import wizard to successfully import text
data files for some time. Recently I used the ascii import option to
import csv files and that worked well. Since I did that, my txt files
come down with negative prices too - so my charts are plotting the
zero for days shares don't trade.
I have tried to find something in the files but I guess the solution
is so obvious it might not be there. Please help, thanks. Raine
