So this indicator is just to show a concept
it based on Bollinger type of fibs with regular daily fibs (upper =red,lower= blue) and the signal produce by the Hull moving average
the idea is to compare the regular fibs and the Bollinger type of fibs so it easy in this way to see where the real low and where the real high
the hull moving average can be set to be faster or shorter for the buy signal. since it open code you can add or change what ever you want
have fun
