The indicator was developed (it’s still in development version so I appreciate suggestions) for use in the mini index (WIN$/B3) on the Brazilian stock exchange, as the first version, but it should work in other assets, but the values shown are not exact.
In WIN$ it tries to show the short and long “term” trend. It uses the different trendlines to generate the TLH and TLL trendlines, and shows the angles of each line in points.
