I have already said that there is a perspective within which the price is located.
But you also need to understand the key price range that will be the focus of this perspective.
Thus, the key level can only be located in an open (not blocked) previously formed area - the range.
Initially, you find the level exactly there, precisely in the key time perspective and precisely in the key range, and only then can you continue your analysis.

*due to the specifics of the formation, this of course does not affect SGL and its derivatives. You can also use SGL to find a key range or level of interest while in a key perspective, but you will need to verify confirmations according to the open range area for maximum accuracy.
Price go Down → You need Range → Last Up movement
Price go Up → You need Range → Last Down movement
