On the one hand, I am not boasting, because the idea is not mine, somewhere here someone (sorry - dementia) expressed an interesting idea ... I asked the factory to implement it. Nice guy jeanlouie made the indicator. Of course, there is no limit to perfection, but the turkey turned out to be quite good, in my opinion.
The bottom line:
the fsand moving bends, the indicator denotes bends/extremes with rectangles, the latter are considered as F/N. You can put several items on the chart with different periods (there are 3 copies on the chart, I marked one tick).
