Known as the BB Squeeze Indicator, its concept is based on capturing breakout moves by using the Bollinger Bands outside the Keltner Channels.
Whenever the Bollinger Bands fall inside the Keltner Channels the indicator will fire a signal. This signal is represented by a red dot on the lower pane.
When the Bollinger Bands breakout of the Keltner Channels the indicator fires a squeeze indicated by a green dot on the lower pane.
