I'm also beginner in trading. I trade since this summer and I lost about $90 on $120 account. Recently I make $20 on last $34.
That's pretty much most of the beginners do, they always lost at the beginning of their journey but the difference between those is that you need to learn your mistake so you don't fall on same mistakes twice.
Throughout my journey in trading, I read Jack Schwager's book, watched many educational videos on YouTube, read many articles on the educational sections of CEX exchanges, and also talked with many traders. It seems to me that I understand enough about technical analysis, trading systems and trader psychology. But I'm at a dead end and don't know what to do next.
Not everyday is a good day for trading you will often get some loss there and there, but if you feel that you are "understand" with the analysis and yet somehow you are still lose then you didn't understand shit. Technical analysis is really deep and all you read at the books and videos don't catch all the possibilities in the market, that's why your experience matters the most here.
Other traders advised me to just trade, but I think that over time I will lose my remaining $45, and demo trading does not bring such emotions and I don’t want to try hard when trading it
Demo trading doesn't get you an equal emotion as you do it with your real money, it's cool to test your strategy but there is nothing other than that.
