Open your mindset in an upward trend; don't focus on the 15-minute or 30-minute charts. Doing so will only affect your judgment and lead to frequent openings, and you won't earn much, giving it all away to exchanges. Now, as long as the 4-hour or daily chart is in an upward trend,
the small pullback on the 30-minute chart can be ignored, or you can wait for a small pullback to enter more safely. I see many people still trying to play super short-term; haven't you noticed that the prices of the coins you are trading are getting higher? Swing traders can enter now; pick a coin and hold it for a few days to multiply your assets.
Additionally, don't focus on small-level indicators; many coins are climbing while being pushed by divergence, which can easily affect your judgment. It's better to look at slightly larger patterns in that process before refining further.
