I tried setting the multiplier as 1 in AssetsFix, and also setting Multiplier = 1 in the script. But it seems Zorro didn't set it as 1 when running the script.



From the above log, if we subtract 25927.05 - 26062.30 = -135.25, multiply by 24 Lots, we should get -3246. But our profit in this case is only -325?

Neither Zorro nor you can change the multiplier. Only your broker can do that. Determine your correct lot amount, then set it up in the asset list in the Multiplier column. Read the chapter in the manual about asset list editing.
