I think like mastering any skill you need to learn, practice, review, persistence.
Learn by reading widely, listening to trading podcasts and watching youtube
Practice by having a demo account or starting slowly with a live account
Review by recording your trades - how is it setting up, how do you expect it go, how did it go?
Persistence by doing it over and over again and being disciplined about how you trade. Your emotions are going to go wild when trading so the last step is really vital. I am guessing that your results have gone south when you held onto something for too long or bought in when you felt FOMO…
And like anyone if you wanna get really go or go-pro get a coach. I am learning from Rob Booker, who I found through YouTube - he is an absolute legend.
