Adaptive Price Zone is a volatility-based trading indicator. Similar to traditional Bollinger Bands, Adaptive Price Zone is a recent development by Lee Leibfarth that overlays two indicator bands around a moving average line.
It is more adaptive than many previous band indicators, using several short-term exponential moving averages which are double-smoothed and closely hug changes in volatility and price data. Exponential moving averages give more weight to recent data, which helps the lines hug current data.
Compared to some other indicators, it is more sensitive in low volatility conditions and adapts more quickly in high-volatility conditions. This indicator is sometimes used in automated trading systems.
