A friend made this for me a while ago, in 2016
Fractal dimension index :
The indicator is RED when the market is in a trend. And it is blue when there is a high volatility.
When the FDI changes its color from red to blue, it means that a trend is finishing, the market becomes erratic and a high volatility is present. Usually, these "blue times" do not go for a long time. They come before a new trend.
Have fun !
