Bubble indicator

A simple and accurate indicator that signals the end of the Bitcoin's bull run. This indicator is an inverted lower Bollinger band , taken from a weekly chart. An interesting observation led to the creation of this indicator: on the weekly chart the lower band takes negative values (the red zone in the indicator) at the end of the Bitcoin's bull run. The advantage of this indicator is that the signal comes in advance.
