The indicator plots 3 types of levels: daily, weekly and monthly. Levels define the highest / lowest / up / down values. Daily levels are determined on the hourly timeframe, the rest on the daily. The indicator can be used to find probable future targets on a chart.
The indicator automatically updates levels for the day only if H1 is selected and weekly and monthly levels if D1 is selected.
I recommend keeping on H1 to see changes in daily levels in dynamics and once a day switch to D1 to up
