The highest point of the market is actually like the extremum of a function; within the range, there is no point higher than it.
To reach this high point, it requires extreme efforts, releasing a lot of positive news, and seeing many large bullish candles, in order to achieve it. After that, there will be no price higher than this within the subsequent range. All bull markets die in a frenzy.
The more it rises, the more caution is needed for the appearance of extreme values.
