strategy tester results differ

 

Why, when I run the strategy tester several times, do the results differ greatly? I'm not changing anything in the EA, or the tester settings. I'm using the "every tick" model on a M1 period, for the GBPUSD.

Thanks in advance.

Because back-testing is not setup to see if the strategy is profitable, it is setup for making sure your mechanical system is doing what it is supposed to, entry, exit, money management, etc..
