Learning without applying is useless, you should learn how trading actually works, how market moves and how to deal with the volatility of the asset that you're holding
You could go even further
That is, instead of learning how to do something before actually trying to do it, you can reverse the whole process. You can at first try to do it and then switch to learning mode, if need be. Yes, you are set to make mistakes, but that's actually an advantage (well, at least as long as the mistakes are not fatal) because you will instantly see where exactly you fail and thus get an idea
what you actually need to learn. In this manner you won't be wasting your precious time and energy learning something which you don't need, aside from avoiding the false confidence that book knowledge provides (and a plethora of errors it sets you up to). This is called experiential learning
It is normal to do mistakes especially when you are in a learning phase, in this phase you do not yet need to do live trading because your main focus is to learn first. Make sure that you have also a good mindset where you think long term and not get rich quick mentality. Observed the new traders who usually got portfolio wipeout in trading, their mindset is so bad where they keep thinking profit than to learn. Mastery = Consistency,whenever you learn a trading system, make sure that you master it and for sure that you will be in the next phase which is the standardization phase where you can able to find your edge in the market.
