Yeah, I think your best bet is to teach people how to trade baseball cards. You cannot just decide you want to teach people to trade and just expect someone to say, "Okay, this is how you do it"
Because learning to trade is not that simple. Learning to trade takes years of experience to be able to do it well, and on any market. So no one here can just post a message that teaches you everything need to know.
If your serious about learning yourself, go join somewhere like Questrade - and read their trading books from beginning to end, that still wont teach you anything hardly, but youll scratch the surface, youll learn terminology and you will know what a few things mean.
Next Id tell you to take an accounting course so you know how to review a company's financials.
Next, Id take some type of securities course and make it specific to what you want to trade, whether it'd be hedging, stocks/options, commodities, power (of different types), futures, or what-ever.
After you do all this, start making small trades on small-cap stocks on Nasdaq or TSXV to practice.
Once you develop your own methodology for trading "WELL", you can teach as a summer job.
Also before teaching consider getting a degree in Economics, Finance, or Commerce ....
then after you've completed the 3-7 years it takes you to do all this stuff, come post back here, and let us know - how it all worked out.
Any type of trading.
Be creative
