I wanna propose two improvement, first of all, can you implement the stability column but, only between number of trades long/short and not between gain.
Second request, the return/DD column splitted in two column Ret/DD Long position and Ret/DD Short Position? Thanks.
I would have implemented it, but the editor is not yet working, unfortunately, and in any case scarce documentation.
There is Trades symmetry column, and you can also specify to use Long or Short side only in column definition, see screenshot.
