Adaptive Moving Average differs from other moving averages in that it uses changes in volatility to transform the lengths used to calculate two moving averages. The two moving averages are referred to as the fast average (shorter length) and the slow average (longer length). The adaptive moving average that was discussed in the interview with Perry Kaufman in the 1998 STOCKS & COMMODITIES Bonus Issue (the article originally appeared in March 1995) is an excellent alternative to standard moving average calculations.
