The modified Average True Range (ATR) indicator. The indicator has been modified for the traders who use VSA (volume spread analysis) in trading. The indicator displays a range of a predetermined number of bars (high minus low), and the average ATR value for the selected period. The indicator visualizes the extreme values of the bar range exceeding the average value for the set period.

Parameters:

• ATR Period - this value affects the number of bars used in the bar range calculation (1 is recommended). The calculated value is displayed as a histogram.
• Average Period - the period of ATR average calculation.
