I am also learning to get trading for a living, but until now even though I already have theory and techniques and chart reading, I am still at war with my psychology which is still very unstable. even though I know what I shouldn't do, I still get used to breaking it, so it ends badly. I don't know, although I often learn to control myself, but in fact it's difficult and hasn't been successful until now. It turns out that it is not easy for day trading, because you have to master complex knowledge to respond to market movements every day
Because indeed the most intimate in trading is mental, because it is the most important basis if you want to be a day trader, I think it is the main fundamental for you friends.
And you need to remember that building a trader's mentality takes a long time, knowledge and understanding only affects a little in terms of cycological, encouragement of fear and greed will be greater at the beginning of being a trader, you still need a lot of time to educate your mentality friend.
I don't think you have to immediately switch professions, you should do it slowly with a small margin so you understand how you should be against your market fluctuations and feelings, if you feel able to control yourself well then the right decision for you to increase your time in trading.
Mentally being ready, feeling cold and robotic, is the best way to trade. I know a lot of traders and I mean professional traders who do this as a job and make a good income, and they all end up trading based on just statistics and nothing more. If you could mentally be ready to trade that way then there won't be any issues and you will do fine.
I think it is important to remember that you are going to end up with a big loss if you do not end up losing money and in order to be better at it you need to focus on how you could trade with logic. Using purely just logic and strategies to make a profit is a great way to make an income and yes there are a lot of people who fail to do that but I think it can be done.
