List Products Respect to Discount Percentage

Hello,
I try to list products order to discount ratio (old price-new price) but I could not found any service method about it. Is there any method about that?
thank you.

It's not available out of box. The standard installation uses Nop.Core.Domain.Catalog.ProductSortingEnum to implement sort order. You'll need to customize the solution to achieve the custom sort.

Hope that helps.
Best Regards,

I prefer this method for this requirement. Maybe someone needs in feature.
I create new table stores calculated product discount percentage. Create new consumer for product entity update/delete/insert and when product has been changed service update/delete/insert to product discount percentage. And I present discounted percentages from that table.
