Bollinger Band Waves oscillator

This is the first version of Bollinger Band Waves oscillator.

I developed a oscillator that uses Bollinger Band and Bollinger Band Percentage Oscillator.
Buy and Sell signal is generated when Bollinger Band Percentage Oscillator break through the 20 day moving average (central line of Bollinger Band on Bollinger Band Percentage Oscillator).


BBW have two, Overbought levels 100 and upper belt line
and two, Oversold, levels 0 and the lower belt line. 

Signals are generated when BBW cross the center line.

Strong signals of opposite directions are generated in Oversold, Overbought areas.
Weak signals of same directions are generated near Oversold, Overbought areas.


Buy signals while the central line is falling are questionable, and vice versa, They should be ignored.
