The premium solution would be:
The correlation is shown as usual when the correlation tab is opened, but a slider is added.
All data are shown as we have it today.
When the slider is switched to the low correlation tab, you open a filter window - which can be the usual one from building an own filter - where the investor can enter his criteria (IAs and performance, DD etc.) and the correlation is calculated between the filter results and the Darwin shown. The result is sorted by low correlation.
Because that might be too complicated, you can also offer all filters saved (standard filters by Darwinex and own filters by the investor) and the step of defining criteria above is not needed. Hypothetically that could be done much faster.
If an investor wants own criteria, he has to define a filter first. If an investor is not familiar with defining filters, he can use the predefined filters shown by Darwinex on the start page.
