You may be 100% correct in what you say!!! BUT I still believe that 'bias' for or against a system really affects the results in a back test if done manually!!!!
And also believe that the test results shall never match the actual results!!! They may be better or worse!!!
Try to analyse Oct 2007 derivative month to 31 Dec 2007 derivative month.

Looking at the period suggested I am convinced that the" bias" does play a role . This is a period where any trend following system has to make money but I will try to select a period which is not very strongly trending and not too choppy.
