Aroon Indicator

The Aroon indicator is used for identifying the direction and strength of a trend and also the change from a trend to a flat. The ‘number of time periods’ parameter is required for calculating the indicator. The number of periods from the moment of appearance of the high and low values within a time range is calculated when the indicator is being built.

Aroon(up) — shows the number of periods, which have passed after the day’s high in the market. Aroon(down) works similarly but after the day’s low.

Aroon(up) = (number of periods minus the number of periods after the high) / number of periods * 100%

Aroon(down) = (number of periods minus the number of periods after the low) / number of periods * 100%

Aroon(up) and Aroon(down) fall in the range between 0 and 100.
