actually there's a lot of tutorials around the internet. And for me IMO if you want to learn more i suggest learn it one by one and create a list for it.
for examples how to use indicators, trend line, and other stuff that very useful in trading, so that you can easily understand how it works and what's the important thing to remember when using it.. Just don't rush and remember to practice it using demo account.
Yes, you are absolutely right, but before looking for indicators, what I would do is read about market speculators in the stock market, how they were able to solve certain situations? what decisions they made in the face of the events they were facing, the reason is simple, because it can be applied in its entirety to crypto and it would be learned to try to understand how the market moves.
If you learn to see how the market moves, it is very likely that you will later learn to make decisions based on it and on the indicators that you learn, thus reducing the probability of losing.
Prepare our mentality and our mindset is one of the things before I go to trading, If we see many people who just enter trading they already brag about their losses in this crypto space since losses can't be avoided but when we face losses we can take some experience from there and move on. Everything will be useless if our mentality and our mindset are not ready to face something that didn't go like what we hope.
