In my opinion, doing research here is an optional activity. If you don't do research, it doesn't matter, maybe you use EA or use signals, but when you use manual techniques, it's best to do research first using a demo account because in the hope that when you do research you can find out what the performance of your system is like, don't let it happen to you. using an inadequate trading system that does not have high accuracy so that your money will not grow later
