How would you plan to implement real trader returns though? Do you plan on selling in and out of positions frequently? Pies are made for long term investing, which is why they don’t automatically update for someone who copies it. Though they are planning to allow updating to occur as there are certain use cases that require this e.g the ARK pies which need constantly updated with the original fund.
My personal opinion is ranking based on performance is a poor option, especially for any new investors who may copy blindly. And I don’t see it being any use, as I think ridiculously high returns is something you need to be extremely cautious of. But maybe a tab for high returns could work? But I definitely wouldn’t sort by return
