This fulfills a request from user: iTibu to make an oscillator to go along with one of my indicators named: "Volume Crop ━ Hidden Volume Divergence [whvntr]". It essentially does the same thing, without the Midline Tool, so you can better understand where the crosses are happening. Again, the hidden MACD Divergence circles formula originated from TheLark. I converted these values to volume instead of price.
