Internet is life now OP. All your questions might be answered on the internet but of course, it was time-consuming rather than it directs to the sites where you can start learning. You may continue using Udemy but don't just rely solely on them. Well, having learned already the basics is enough to start as the reality is that experience gives you more learnings.
So far, the best course option that I have seen is a demo account. This is how I learned to work with a broker from Amarkets, and I am really satisfied with my result.
Don't consider a demo account as a course. This is only for the intent of giving you a view of a particular trading site but never it teach you strategies that you can use in actual trading.
