================================================================================================
Project Description:   

This indicator calculates and displays a set of polynomial regression bands. You can select the 
polynomial order (1-4) and the number of standard deviations to use. The outer bands are standard 
deviation of price (conventional) added/subtracted to the basis line while the inner bands are 
standard deviation of the difference between price and the basis line.

Typical usage would be to apply the indicator in conjunction with moving averages. When price closes 
above one of the upper bands, look for a moving average cross down as an entry signal. When price 
closes below one of the lower bands, look for a moving average cross up as an entry signal.
