I would put them through the BP school, have them open a demo account and tell them to learn their trading software. I would also advise them not to view any videos on YouTube or follow anyone out there. Thereafter, I would tell them to trade the demo account.
After 3 months, once they have finished the steps above, I would start them on their education while practicing on the demo. Within 6 months after that I would expect them to become profitable. So, a 9 month journey from start to consistent profits.
Subsequently, experience is all they need to become a master trader. There is no getting around that. You need to experience the vagaries of the market for yourself.
