Emotions are one of the hardest things to overcome. I too was a day-trader, not saying I was successful at it, but I did try it for a while, and emotions has to be thrown out of the window. The main thing I focused on as a trader was the chart, the chart tells it all, and not necessarily saying that it is gauranteed truth, but if you think about it, what ever you see on a chart i.e. bull flag formation, everyone sees the same thing and will react similarly, and the same goes with a bear flag, and all the other indicators. Learn these charts and you will have a sense of direction...However, what I have learned since investing in crypto is that they act differently than stocks right now, 50% swings are the norm lol...
