Faced with the problem of duality (which means priority) and uncertainty of the levels in an open candle, I thought…
"Then how can we make the analysis more accurate?" "Then how can we identify the desired level?"
And I got a revelation.
I consider the price reversal as an "Extreme + Level", which means that the Extreme is formed due to the level and can indicate it.
You see, an open candle is a consequence of HSL, Extreme is a consequence of HSL.

As you know, the price is not immediately ready to give you a confirmation after it reaches the level. Then using SGL becomes problematic because only by passing through the level that the price forms by targeting lower priorities (levels), that is, the maximum or minimum itself, and not the level - the reason, can you judge that the price was exactly at the level.
This means that if you want to be confident when selling, you need the high, and if you want to be confident when buying, you need the low.
It is also interesting that you can find the maximum or minimum in a shorter term precisely inside the minimum or maximum itself and thus.
And also you can not shorten the perspective, but simply select the level that is located earlier.

By itself, the "not saying that the level is exactly there" maximum or minimum that does not correspond to the orientation that we want to occupy will be the level at which we understand that the price may have been at the level we need. If it is available, you can start monitoring the price and be ready for a position.
According to this logic, you can understand that the extremum that we updated earlier is always the minimum price target after confirmation from.
It should be understood that you should divide them based on perspective and the range under consideration into high strength and middle strength.
