The 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...
The Double Smoothed RSI Indicator was created by William Blau (Stocks & Commodities V. 9:5 (202-205)) and is a variation of the classic RSI using his Momenta Indicator and his Momenta RSI formula. I have color coded everything to make it very easy to determine buy and sell signals.
Let me know if you would like to see me write scripts for other indicators!
