There are several traces of newbies finding signals here and there to trade, but it is wrong. Believe me If you want to trade consistently and profitably just learn how to do it yourself no matter how difficult or how long it takes.
You can subscribe to signals if you're the type who wants to earn while you learn but long term.... Learn trading by yourself
when we experience losses there we learn something and will definitely understand the condition of a market. I think those who buy premium channels also want to get rich quickly, whereas if we really want to learn it for sure we will be better than those who want to get rich quickly.
You are right; as traders we are supposed to learn from trade mistakes; but also do you know that it is hard to correct a trade mistake if you do not have a trade strategy? or you cannot trade by yourself ? This are angles we have to look into as traders; as much as we do our own researches; there should be a process and a trade strategy too.
