Doing research has a lot of benefits when you do research, you can know whether the method is working well or not because usually a trader has a lot of knowledge and doing research, they know which ones can be used as trading systems and which ones can't. and doing research, in my opinion, is not an obligation, it's just our own desire as traders, but it would be good before you go any further, you should do research using a demo account so that you have a good trading system.
