Indicator/Study to show largest high-low in previous X bars

[Tigger]

Hi,

I am looking for an indicator/study to show the largest high-low (peak-trough) that has occurred in the previous X bars. This is sort of like ATR, but in my view it is a bit more defined and useful.

Is anyone aware of such a study in Motivewave?

thanks!

There are a few that have this description on there but I don't know which would be closest to what you're describing. Boilinger Bands ATR maybe? I know there is something closer to what you want though.
