We call something like that "garbage in garbage out". Zorro results will be wrong when you entered wrong parameters in the asset list. If the parameters are very wrong then the results will also be very wrong.

Exception is when the results are not calcuated by Zorro but available from the broker API, this works normally with MT4 but not always. If you get wrong results from MT4 then you must use Brokerpatch to let Zorro calculate them.
