How do I find a mentor that has lots of experience doing this stuff?
Online and also in person.

Somebody who knows what they are doing for a long time now.
In my opinion, you don't have to find a mentor to guide you on doing trades, there are lots of people who have learned trading on their own because there are lots of videos and resources on the internet it's just up to you what knowledge you'd want obtain. Maybe before you deal with this venture you need to know all the disciplines when it comes on doing a trade.
