I need help understanding what's happening here, any input would be appreciated.
Here is my code:
import1 = importdata('Historical_Data/ES.csv');
price_low=import1.data(:,1);
I'm reading a .csv file with values like the following
Date,Low
2/17/12,1353
2/16/12,1334.25
2/15/12,1338
2/14/12,1337.75
The values are being save to my array as
1.3530
1.3342
1.3380
1.3377
I'd like the value to be the same as they are in the file.
Is this an ASCII issue?

Are you sure? If you look closely, you'll see the display is saying '1.0e+003 *'. That means your numbers are correct, but are being shown in scientific form.
If you really want them to look identical to the input file, read them as strings with textread:
filename = 'Historical_Data/ES.csv';
[mydate, myval] = ...
textread( filename, '%s%s', 'headerlines', 1, 'delimiter', ',' );

Yeah, they're the same numbers. MatLab just declutters the view a little in the command window by saying "ah well, everything's 1000x".
