Praveen Bhai, dil kee baat bo loon, bura mat maan na..
I am sure your 14 yr old son is lot more smarter then you were at the age of 14yr. We should not underestimate our children and do everything for them. Rather give them enviorment to find out themselve. Time has changed and they are lot in tune with today's and futures time, technology etc then we oldies.
As a parent our job should be to make them hungry - hungry for success, hungry to be the best in whatever they are doing, hungry for money and happiness etc. and develop enough confidence so that they know how to satisfy their hunger. (and diplomatically, convince them that trading business can meet all the requirement...cause if he does it right, then by the time his classmates are joining company as trainee after collage, he would already be earning more than the managers of that company).
I would rather send him to good mentor/ trading course etc to get the foundation right and give him small account to manage. You can give him a system, but you can't develop his mindset with a system.. and as you know it well, in trading, our success is given by what is in our mind, how we handle our emotions, how calmly we take the decision etc.
Just my views on this topic Praveen bhai. You know it well regarding what is best for him.
(lucky him - that he got a father like you. Hope he knows it).
All the best
