This indicator marks the opening, high, and low of the Globex range in futures (6 PM ET - 9:30 AM ET). In addition, it also will calculate and plot the 1st and 2nd standard deviations above and below the globex range. These levels can be used as support and resistance in the New York session (9:30 AM ET - 4 PM ET). Price often respects the globex range to some degree during regular trading hours. This can be modified for any time range you prefer.
