Happy New Year,Roman!
There could be few reasons for getting no results with any pair.
1. How long Historical data do you have? Please, check if the data is fine. It could happen that you have missing period in your data.
2. You have placed too strict acceptance criteria during the generation.
Try to remove the Acceptance criteria and run the generator. If it starts showing strategies, than start increasing the criterias.
3. If you use Monte Carlo and Multi Markets, make sure they are not strict.
It is better to get many strategies and after that to filter them.
