Description

The Adaptive Price Zone indicator from the S&C, September 2006 article "Trading With An Adpative Price Zone" by Lee Leibfarth is a set of bands based on a short term double smooth exponential moving average. The bands form a channel that surrounds the average price and tracks price fluctuations quickly, especially in volatile markets. As price crosses above the zone it can signal an opportunity to sell in anticipation of a reversal. As price crosses below the zone it can signal an opportunity to buy in anticipation of a reversal.
