Technical analysis for me is like a weather forecast. You are trying to identify if the current volume of stocks exchange is going to be fatal or not. This is very easy to understand but hard to perform especially if you do trading. As far as i know there are to type of TA the short term view and the long term view(Which is obvious).
There are a lot of key factors for a technical analysis. I don't know the other since I am not a pro trader but I only know one thing the High liquidity. In which you can easily identify based on volume that you can see in every exchanger sites like binance.
For example: currently binance top volume coins are ETH and EOS. Since this type of coins has a huge number of volume the price can be very volatile more than any other coin. This could be the key for traders to dive in and out in a short period of time.
PS: I guess you should have explain the topic more rather than letting us to watch a video cause that might be just a form of marketing strategy for you to gain more traffic on that video.
I also see him as wanting to promote the video, rather than analyzing it for the community. The form is superficial lack of professionalism. Technical analysis is just a reference and everyone can do it. Is it important that they are analysts? Or just a regular user, making videos for multiple views.
