I find that some ranking option like Z-score has both positive and negative value.
But if I want to set the value big than 1.96 or small than -1.96. I find it can't be set in the filter correct, because Z-score can't be big than 1.96 also small than -1.96 at the same test result.
If I want keep my strategies "Z-Score big than 1.96 or small than -1.96" how I set it? Or can you help me to add a feature to do it, thank you.
Then its value will be always positive.
