Okay, the optimize function writes the following .par file:

AUD/JPY 10.8 50.2 120=> 8.705
AUD/USD 8.11 70.7 140=> 2.156
EUR/AUD 9.81 70.1 270=> 1.770

where the first and second parameter are time periods of SMAs. I guess they are rounded to int when used in test & trade according to your answer? 10.8 to 11, 8.11 to 8?
