This indicator plots horizontal lines for the high and low of each of the last x (configurable from 1 to 20) bars, each of which may be anywhere from 1 minute to thousands of minutes--preview image is for 90-minute bars. I have found that it goes nicely alongside the daily version of this indicator.

Release Notes:
Updated to select color as an input (otherwise you'd have to manually change it 20 times in the style tab). Changed default bar length from 120 to 108000 minutes (75-day-long bars, so you would have 20 75-day minimums and 20 75-day maximums plotted). Take a look at three versions of these added to the same chart at different, very long-term bar lengths!
