Calculations of the fluctuations range for the present day are published in this section. That is, at the very beginning of the day, you can determine the maximum and minimum of this day (with a known probability).
What does this information give? In fact, a lot. But first of all, these are guidelines for trade. For example, if during the day the price approaches the upper (lower) mark, you know that it won’t go above (below) this mark with a particular probability today. Accordingly, you can open a position opposite to the current movement, knowing in advance what the probability is to be profitable.
