You are one person which i see who said that trading is more risky than skill based gambling. It is your experience, that's why you are saying it, but in my experience, i know skill based gambling, depend on our skills, so same thing is happen in trading. We do trading behalf of our skills then i don't see any different between skill based gambling and trading, for me both are same.
I agree. You see skill based gambling is a lot more similar to trading than most types of gambling games. You'll have a good chamce of getting good results if you prepare and study first the aspects that can give you an advantage. That applies for both.
