Is it really necessary to take a course before getting into trading?
Sure... That's the first step forward a successful trading experience. Trading isn't as simple as it may appear, so the best thing is to seek and acquire knowledge. Any trading journey without prior knowledge is liable to fail.
Acquire the needed knowledge, practice on demo as much as possible to gain experience. When you're ready for the task, no one will tell you but you will have the conviction yourself.
Trading is sweet when you get it right.
Wish you a happy trading experience
