Technical and Fundamental analysis exist because they have a huge function when it comes to trading. Some just use TA, well, they are still profiting. That is why it is still an option for us traders which one to use but I suggest to consider them both upon trading as this would help you to have better results. But we have to remember that trading is not just all about TA and FA, in order to earn profit from trading, it should also be accompanied by effective strategies and hard work. In this way, your chances are pretty high.
I would suggest both as well. They both have some usecases in each situation and to be there and promoting it means a lot and should be promoted for sure. It is a clear indicator that we should be able to get people to use both of them if you look at the results from both of them.
Just because you are using one doesn't make the other one useless, there is nothing that blocks you from using both of them and that is what we will get in the long run as well. We are going to end up with something profitable if we use both, and if we use only one or even not use any of them then we are going to miss a big portion of the big picture and end up losing money in the long run.
