Instead of averages, how about moving minimums or maximums? The inputs for the calculations are the same as for the moving averages except now its calculating the lowest or highest value over specific time period and then, rolls or "moves" this min-max forward in time. These calculations could also be centered by taking the lowest or highest values from a set of data points located around the middle point of the rolling time period.
