Yes it is definitely true that if you are not suitable for trading then you should leave it. For example if you keep losing or you cannot control it. I have been trading for a long time and have gained knowledge but there is no end to learning I have put it on hold for now from my experience I would say that market analysis is important in trading. But if you want you can do spot trading this is my preferred trading which I do. If you do not want to wait for profit or want to do it for short time then you can do spot trading which will be good for you.
