OK, just got the assets from my IB demo account and saved them in AssetsFix file. Strangely, the leverage field on currencies was more than 1 even though they have 10mio margin requirement for ForEx leverage! oO

After a test run of z12 the report numbers changed somewhat.

BUT! When I set all leverage fields to 1 in AssetsFix file, the z12 run returns the same results and same margin requirements! This is kind of strange. z12 does not leverage the trades usually?
Could someone confirm if you observe the same behavior?
