The stock markets are very risky for children to learn the ways to invest. Many children become speculators/ gamblers if they aren't disciplined in their behaviour after they reach the age of 18. I think the probability of winning is about 20% for novice players. In case they are lucky to win in their initial investment, their confidence is s multiply many times n they may decideff to invest on credit. If the market turns the other way, they may incur heavy loses n even become financial delinquent. Their parents may have to foot the bills outstanding. Hence I will not teach my children to learn investments
My experience with Tiger broker's trading platform is akin to encounter the Thai girls in the land of smiles (Thailand). A user friendly software indeed.
