WRONG values of ATR in BACK TESTING

Hi,

I am trying to get ATR VALUES on BACK TESTING and plan to write them into a CSV file.  But when I compare the values I am getting in BACK TESTING and the Values on the ATR Graph of the same date and period, it is TOTALLY DIFFERENT.  HAve copied the whole executable code over here so you can run and see the values for yourself.  And then manually cross-check these values on the Graph.  

a little help is required. Thank you.
