@DdlV: I installed Zorro into a new folder when upgrading and only copied the desired files from the previous version into the current one.

Hi Sundance.

Re. upgrading, I actually do the reverse - make a complete copy of the retiring Zorro folder into a new one, and then install the new Zorro into that new folder.

Re. upgrading & Margin, to continue with the same CR the correct new Margin needs to be determined by Testing. I was wondering if not doing that and continuing with the old version's Margin setting would have produced this kind of situation? A question for jcl...

Yepp. I tested now Z12 in the new folder and now I'am trading live with 1000€ and Margin set to 10. We will see...
