This is a volume indicator that splits purchases and sales into 2 separate columns.
In addition, I added some POW factors to scale the volume to a more compact or expanded picture.
The SMA draws the red line indicating the volume of purchases and sales, also with POW factor customizable, so it is possible to scale it within the volume bars
what to do with this information: it is very easy to find rotation points when the selling volume and the buying volume are equal, this is where possible rotation phases occur
have fun
