Not really that far and I take trading is just like the same about gambling. For the fact that gambling doesn't rely on luck but also on knowledge and skills, the same thing we need for trading, and sometimes we just wish for some luck for a better trade. Maybe if we are in the lottery, that consists of luck only but we are not talking about that, we're talking about gambling in general which shows how important to have those things (knowledge and skills) the same thing that we applied in trading. Well, of course, it was in the different strategies and market applications.
I know that some people won't believe this but if you were in trading, you can really picture it out.
