Now that the currency I have placed my trust in is only lateralizing, but I have full confidence that it will not go down, I have decided to forget about looking so much and go study and train myself.

I have found two YouTubers who teach a lot and explain understandably, but I stuck with one whose technique I loved and his way of explaining. Obviously, he has his signal group and that, but mostly he invests in assets, forex, and binary options, but in his class, he says it applies to crypto. The truth is that there are a lot of videos or tutorials. And particularly, I lack time, as between taking care of the house and this analysis, plus a book I am writing on another topic, obviously, uff, I lack time.

I wanted to know if someone could resolve a few doubts for me, but especially the first one:

If a candle is coming down, let's say, but I don't know how to say it, but the upper price exceeds the previous one and shows a trend change, and when going down, it exceeds the minimum showing lowering, what does that mean?

Or is it lateralizing and shows an upward indication, and when going down, the lower price shows lowering, what does that mean?

The topic of indicators and which is better

The topic of Bollinger Bands, according to what I see when it opens, is that there may be a new drop or rise, depending on which price exceeds.

I like to observe the MACD and volume, and in my novice stage, they have helped me a lot.

I know that many set the moving average to 50 periods, but I have not tried it yet.

But the RSI that I have seen many look at, I do not understand at all, could someone summarize for me what it is for and what it shows?
