Not only it would require a skill, it requires a dedicated focused time as well, which isn't that easy. This is why there are people out there who trade only for 1-2 hours a day, that's it. Main reason is that if you want to make any money from trading professionally, then you need to be locking your eyes on the screen, and looking at the charts very carefully, even a tiny miniscule information can't pass you without you noticing, you have to see every little dot, every little change, every little action.
This requires an insane focus, and you can't even take a smoke or toilet break. This is why they try to keep it just one or two hours a day, and if you want to do more, you need to take a long break after each one to gain your senses back and to be able to repeat it. I believe that most of the people are just trading for fun, or trading part-time, not as their job because most people cant do this as a job, it is not easy and causes a lot of trouble for a lot of people.
I agree, I have seen some people (on youtube/tv etc, not real life) who are professional traders and watched what they were doing, and they were quick too.
It is not just about how they have to have focus, but it is also about how quick they are, like they were basically soldiers in a war, with their gun, if they don't see it first, then they will be seen first, they were incredible agile whenever they saw something, they click everywhere with memory very easily in a second.
Like a trader who could look at 100 different pairs in a minute, and can execute a trade in 7 seconds is something dangerous, and that is why I stopped trading daily after a while, I realized that I could never beat those guys and they will always be better than me, because of how hard they work and how fast they work.
I believe that there is no need to be a trader like that, you could just be a trader who buys and sells in span of maybe ten days, like you don't have to act quickly, you do not have to do futures neither, just buy something, wait a week or two, and sell later. That type of trading is easier, because it allows you to make some money without having to deal with anything harder, and make money easier, less money, but easier.
