I tried one but I falied. There is something I don’t know? Please tell me more.
I would suggest to first learn the basics of Technical analysis, learn the basics of charting, learn what each candle tells you and how the support and resistance works.
And then when you feel you are ready, (you will know by testing your skill, read charts) 2nd step is to know and improve your emotion. Put and keep only the money you can afford to lose. But not to actually lose it, but to clear your mind about it and start thinking only based on the charts and technical analysis.
no FUD, no FOMO just pure analysis.
