I can't share any specific channels or resources, so, as I can see many folks before me have already done it, I just want to guide you a bit.
If you are going to delve into trading, then self-education is one of the most significant parts of it. I just wanna share some ideas on how to distribute time correctly. Use 70/30 scheme.
70% of time you should learn new things, pass courses, watch videos, webinars and so on.
30% of time you must practice on the demo, but don't abuse demo trading, as it has quite unpleasant consequences.
