This is a scaled version of the Forecast Oscillator, paired with a Point of Force Indicator, my modification of an indicator, whose original name and developer happened to be missing on my notes, so my regards to the author).
Point of force is a spot from where price action will dynamically evolve in the same direction or soon reverse and pursue that reversed path. It may be an indication of a turning point or entry point to consider going long/short and should be use together with a background oscillator showing a prevailing local trend.
