the real problem about trading is how they thinking about trading it self, it's not a gambling, some good traders who i meet a year ago say trading is a precision , its not about profit u got earlier and go back trade and feel u can do it again, its about the right time to in and out, how to get that, training , TA first then FA follow. He told me trading no need a luck , just a precision, well i talk like a pro but i still noob at it 
Trading techniques differs in every person, some where too good in technical but still isn't able to get much profit, same if they only knew the fundamentals. It's through experience we will be able to realize what method will work best on our trading as it differs in every situation where in like if the market is at red or when there are news that affecting the pump and dump of prices. It's through experience we can say if our profit in our early trading is worth it or just luck to start in trading.
