Trading or day trading is not an easy thing because you will experience anxiety wherein you can't be comfortable because you know you have open trades, which may result in monitoring your open trade throughout the day, which could affect your decision. If traders will actually follow the steps or instructions in your picture, then maybe they can be a profitable trader, but of course it still depends on their knowledge and how they can make a good trade analysis. This kind of topic is discussed numerous times in this forum, but the thing is, if this kind of advice doesn't reach those traders that don't lurk here, then how can they know what they should do?
First of all they have to master a subject and study a lot in that subject. Trading is really an uncertainty.
It is actually very difficult to do well here and excel in it. I know this has been discussed a lot before so I thought I'd share my experience since I'm new to trading.
