emotions do not belong in day trading. It is already stressful enough, and the computers and systems analyzing charts do not have emotions like you do. So if you are crying after losing some money, just remember the computer doesn't have feelings, so it will have a big advantage over you.
No, emotion will belong to day trading, and even the feeling will become too high in the day trading. Imagine you search the right coin to trade, but you cannot find anything good even if the market has a good moving That will make you stress and you cannot think clearly so that will impact your day trading.
I already got that experience before, and I admitted that really annoying for me to find the right coin. But later, I realize that I need to calm down for a while so I can analyze and search the coin. After that, I think I can always calm down in searching for the coin, although the coin cannot give me a big profit, it will be okay for me.
