Thanks both!

@MatPed: There's so much about this I don't fully understand yet... I hadn't even really gotten to the OptF's on the belief that they're driven by the backtest results...

@jcl:
a) Isn't it more complicated than that? I.e., the trades taken aren't exactly the same, so while more leverage is involved that doesn't a priori mean bad (-12.5) must become worse (-42.6). F.i., SPX500 changed from losing (-13.8) to winning (11.5). Wouldn't optimizing using the different AssetsFix.csv therefore produce different results than using the leverage 100 values on a leverage 200 account?

b) Finally getting to OptF's , would the 0 OptF for XAU prevent it being Traded and therefore Trade would give better results than the Tested 30% AR (which includes the XAU loss)?

Thanks.
