In my opinion, trading is not an very easy way to earn money, like what some people think. There are many good traders who lost a lot of money in trading, even those with lots of experience.
Yes of course it's so difficult and unpredictable cause you need luck sometimes and luck you can't predict at all.
Of course the better you are the more consistent you get but still very difficult in my opinion.
I can say that I am lucky sometimes in trading but I do not use it as a measurement of my success as there are also times that you are unlucky so that is just the same if you will try to analyse it, the real way to earn in trading is our skills and knowledge.
