They make you really believe that is more like a skill and if you are good at it, it works.
My friend told me that is just about how lucky you are, and not a skill.
So, should I stick with holding or playing day trade is a better option?
Well for me that luck that Have is the skill of person and the idea and a persons knowledge. I would suggest that you should not think that way because if you are trading you use your knowledge the things that you learn when it comes to trading and when you win it can be called luck but remember if you did know any background of day trading you can not win you do not have any so called luck.
So here is the thhing call it a luck "luck" if you do not have any knowledge when you earn something from out of nothing.
