Oh! You’re very young! 
I’m happy you discovered forex this early. 
I really hope you succeed. Have you checked out the school here?
Hello and welcome to the forex. Hope you can make a good trading career in the future.
Welcome to the family. Wish you a good and profitable trading career.
This is so great that you want to learn trading this early in your life. You can start by exploring demo account first and with different brokers so that you can choose from them. You should also familarise yourselves with all the concepts in trading like stop out, take profit and stop loss. It will help you in future. All the Best!
That’s great, It’s actually good that you are so focussed at a very young age. You can gain a lot of knowledge since you have ample time and by the time you are in your 20s you have the required experience which will help you to earn more.
