This indicator measures how 'overheated' the bitcoin price is by comparing the slope of two multiples related to the closing price. This indicator manages to identify each top in each halving (4 year) period for bitcoin.
The indicator shows bitcoin reached the ATH for that halving period when it reaches above '0'.
This indicator is showing that there is some more upside for bitcoin but the top may be reached sooner rather than later, it works only for bitcoin on the 1 day timeframe and is unable to tell how far bitcoin will go down after the top is reached.
