All brokers are providing it but to make it better you can add risk mangement to it to stand out from others something like smart intelligence where you can add amount or money you are ok to loose depending on that ai decides your quantity its just a suggestion it sounds cool to me bcs when peoples are new in trading they dont know anything about risk mangement so they keep on adding quntities in loosing postions but they dont know they are just increasing their loss by doing it.
If its not possible atleast provide basic one
