Oh ... then I missunderstood. I thought with the HistoryFolder variable you can select a new location for the whole content (all files) that are default in the folder "History" in Zorro's directory. I didn't know that this concerns only to the price files, therefore I used AssetFix.csv as indicator if Zorro recognized the new location (because if not it claims already at restart with no further action needed). Thanks! I will try again.
