I would focus on learning market structure and then use market structure as the foundation for the strategy you develop. Indicators can be used for confluence to support what market structure is telling you, such as using RSI to check for divergence.
Learning market structure, beyond identifying an uptrend or downtrend, isn’t as easy as loading up indicators but I think you will get more mileage out of it and it’s useful for a wider variety of instruments.
Theo (who posted above) is being terribly polite and tactful when he says his “guess” is that it’s no good. He knows perfectly well that it’s no good, and so do any other experienced traders reading your post. Not many will reply, probably, because most people don’t want to be “the bearer of bad news”.
And because there are a few people here who have the habit of accusing anyone who says anything “negative” of “being negative and unhelpful”. And that inhibits many people from posting, when the only honest answer to something is “no”.
The big issue here isn’t actually whether what you’re asking about is good or bad.
It’s the mistaken underlying assumptions you’ve originally made, that made it possible for such a question to arise in the first place.
You need to start by correcting those. Which actually isn’t easy (for anyone!) to do.
The big point, here, is that there isn’t going to be a combination of any 5 (or 4 or 3 or 2 or 6 or 7 or 8) indicators which you can put on a chart and follow, which will magically enable you to trade crypto profitably.
That just isn’t how trading works. At all.
So at the moment, you’re going in the wrong direction, I’m sorry to say.
Please forgive me if I sound critical or even impolite. I’m trying not to, but to have any realistic chance of trading profitably, you need to hear and understand clearly that a fundamental re-appraisal of what you’re doing, from “square one” is required, here: not an answer to a question about some specific combination of indicators.
The proportion of people who take up trading, and ever become steadily profitable, is (to put it mildly) on the low side.
Three of the major issues that keep it very much on the low side are (a) people trying to trade crypto, (b) people trying to use indicators with the mistaken belief that they’re going to have some “predictive” powers, and (c) people not starting from a clear understanding of the difference between a trading system and an entry-method (as Theo also mentioned).
I respectfully suggest that you start here (and with the forex course, specifically, not the crypto one) -
