What is the reason for doing that? Just let the kid play with his toys. The children in his age really need to play, not to learn.
Mr Alpha T+ son; Sounds like a wise idea; i just ''traded a Little Engine That Could, video'' To a library for 7th Pres Andrew Jackson Book... See son ,we sell, like when the train[price] starts+/ gong down-hill .============================================================================================================= 50 days moving average..... should help define ''hills + valleys'' Tell him its fun[trading-investing is NOT gambling] no matter which way the train-[price moves]!! One share starting size sounds fine; i dont think i would fibo, or make him draw trend lines, but trend lines like auto drawn 50dma should help.5 year old girls read ; dont worry if he can, or cant read words much yet. I was reading words @ 7 ; but pictures long before..... AS soon as he is profitable /obeys orders, maybe you can ramp up size + give him some profit sharing. Let us know how this turn out for the better, Alpha T.
If it were me I would focus more on the hard rules of your strategy than on the why at that age. Kids understand rules like no desert before dinner and 2+2=4. They don't understand the why of the rules and they don't really need to. So I would just teach him that you buy when this happens and sell when that happens. All of the complex why details can come later.
I have 3 kids and voted no. If a kid believes in Santa Claus, it's too early to start teaching them trading, unless they absolutely want to. However, I would seriously worry if my 5 year old would rather trade than play with friends.
So if he spends 15/min a day or so educating him, that is going to totally deprive him of fun in his childhood? Maybe he shouldn't go to school then because that will deprive him of fun in the name of education for a LOT longer.
