1. RISK: the biggest thing wey separate gambling and trading na risk, for the two risk dey sha but with trading you fit control your risk, too many parameters and avenue dey to control your risk, for gambling the chances to control risk dey very slim.
When it comes to risk, I don't see much different between trading and gambling. Both involve risk just as you have said earlier. I'm into sport betting, and this days punters have upgraded their site to help bettors in managing their risk. One of it is the cash out technique, if a game is going against you, you can easily stop your betting by clicking on cash out immediately you lose hope on the match.
