Adaptive Price Zone (APZ)

The adaptive price zone (APZ) is a volatility-based technical indicator that helps investors identify possible market turning points, which can be especially useful in a sideways-moving market. It was created by technical analyst Lee Leibfarth in the article “Identify the Turning Point: Trading With An Adaptive Price Zone,” which appeared in the September 2006 issue of the journal Technical Analysis of Stocks and Commodities.

This indicator attempts to signal significant price movements by using a set of bands based on short-term, double-smoothed exponential moving averages that lag only slightly behind price changes. It can help short-term investors and day traders profit in volatile markets by signaling price reversal points, which can indicate potentially lucrative times to buy or sell. The APZ can be implemented as part of an automated trading system and can be applied to the charts of all tradeable assets.

The APZ is based on a set of bands that form a channel that surrounds the average price and rapidly tracks price fluctuations. It provides a method for analyzing price action and identifying potential turning points in the market. Depending on an investor’s interests, the APZ can be adjusted to any time interval, from every five minutes to daily. The APZ tends to be most useful in periods of sideways price movement when there are no clearly marked trends to follow.

The APZ calculations form two bands that appear over a price chart, which are neither uniform nor symmetrical. The simplest method for using the APZ is for an investor to sell when a price surpasses the upper APZ band and buy when a price goes below the lower APZ band in anticipation of reversals. Periods of high volatility produce wider bands, whereas periods of relative stability produce much narrower bands. The crossover points between the price line and the AZP bands help investors determine good trading opportunities in unpredictable, choppy markets.

Technical analysis is one of two major methods for making stock-trading decisions. Whereas fundamental analysis looks at the value of the company behind the stock and its recent announcements and developments, technical analysis ignores this completely and focuses solely on recorded price movements. Technical traders use charts and other tools to analyze a stock's price and trade volume and predict how a stock will move. As a technical analysis tool, the APZ helps investors spot reversal points that signal a high probability of a switch in direction.
