I can't reproduce your Z3 annual return of 136%.
Deleted Zorro directory, install of 1.58, copied the history files *.t6, using fxcm demo account and leaving account name and password empty.
So I have the default ini file, the default slider settings (margin 50, risk 10) and no broker influence hopefully ...
Nevertheless I always get the same result as described in my first post of this thread - req. capital 1426$, AR 79%.
What am I doing wrong to get a such differing result?
Kind regards, Peter
