Indicator Adjusted Average (IIA)

Indicator Adjusted Average computes a Moving Average whose period varies within a specified range and is determined based on the value of another indicator within that indicators range. The indicator used to control the variance of the moving average period can be any of the 80+ predefined indicators or even a custom indicator created using the Investor/RT RTL language.

The development of the Indicator Adjusted Average was inspired by the article Variable Interval Moving Average in the July 2001 issue of Stocks and Commodities Magazine. The best way to simulate the Variable Interval Moving Average is to use a Volatility Indicator as the underlying indicator in the Indicator Adjusted Average study, and assign a range of periods from 10 to 50.

The range of maximum and minimum volatility values will be calculated, and then compared to the volatility values for each bar to decide which period between the maximum / minimum range will be used to compute the moving average for that bar. The Indicator Adjusted Average may also be used in the Investor/RT Scan language to automatically search for crossovers or breakouts.
