$open= $arr[3];$high=$arr[4];$low=$arr[5];$close=$arr[6];

Then I do some calculations using these:
The chunk of the code that does the calculation is:

    if ($close<$open) { $stretch=(($high*100)-($open*100));
                     $stretcher=(($open*100)-($low*100));
                       $identifier="Red";
    }
    if ($close>$open) { $stretch=(($open*100)-($low*100));
                     $stretcher= (($high*100)-($open*100));
                       $identifier="Green";
    } 
    if ($close==$open) { $stretch=(($high*100)-($open*100));
                      $stretcher=(($open*100)-($low*100));
                        $identifier="Doji";
    }


print "$date $time1 $time2 $stretch $stretcher $identifier $open $high $low $close\n";
