My suggestion… learn one entry and exit, master that one entry until you can do it on all time frames… with good success… and then attempt live account.
Do not try to master every concept and lesson, you need only one valid entry that you master.
You may always need to practice and refine your skill.
After many years at this game, I still do replay several times a week to see what I can improve.
Again. one entry that you have mastered…!
