Such as me, I do long term investment and I believe that it is not going to be all that confusing or great, I believe that we are going to end up with something that would be a bit harder to handle and we should not really focus on the indicators. I am not saying short term traders shouldn't, if you are someone who does day trading that indicators are all your life, it is just part of your day, and that means you need to learn them like back of your hand.
However, we need to figure out a way to just hold long term, find some money to do that, and then we do not need indicators if we do that part. I personally hold long term, so indicators mean nothing to me, I just buy and hold, what could indicators do to help me with that.
Not long ago I watched a video with a market maker who talked about how they can influence indicators in certain trading pairs, so manipulators can play on traders' expectations. I think this is possible at a local level, so it will not have such a big impact for long-term traders. Day trading is one of the most difficult, and it will be very difficult for a beginner in this type of trading to make money, but as practice shows, beginners most often decide to start with day trading.
