Indicator: Vertical Horizontal Filter (VHF) by LazyBear

VHF determines whether prices are in trending or congestion phase. Rising edge signifies a trend, falling edge signifies prices may be entering congestion phase.

Many use this as a contrarian indicator, which is my personal preference too.

I have added an option to plot EMA too, to see how strong the trend/no-trend values are.
