ScriptFree

The average true range formula records the maximum values of the following three differences, and calculates the moving average of the resulting data series:

Between the previous day's high and low prices.
Between the previous day's close price and the current day's high price.
Between the previous day's close price and the current day's low price.

The average true range indicator is a good measure of commitment. A high value often indicates market bottom due to panic sell. A low value often indicates market top.
