Adaptive Price ZoneThe Adaptive Price Zone was developed by Lee Leibfarth in 2006, and it attempts to create a band for mean-reversal strategies. It works by taking the double-smoothed average of the volatility from 5 days and adding/subtracting it from the average price of the day (hl2).
If you are planning to use it, remember that  it changes throughout the day , so you might want to use an offset. You can also choose to use the true range for the volatility instead of the high and low difference.

 Second strategy
 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.
