How to style the map with shaded circles in ArcGIS

[SlobodanKomatina1]

I have a points with field values that I want to use as circle size in visualization. Actualy that will be some kind a buffer depending on field value but I need these buffers to be a little transparent so the overlaping buffers have a darker colors on places where where the most buffers overlap each other. I want to do that using ArcMap.

This is what I want:

Did you try a proportional symbology with a transparency set?

I don't know if the overlapping circles will produce the darken you need

[SlobodanKomatina1]

Yes, I have tried but all circles are transparent on the same transparency. I need it to be just like that on the picture. Maybe if I create buffers around each location?

I thought you had buffers around the locations already and some overlapped.  If there is no overlap, you might have to try to change them individually, 

In PRO, you can have a look at....
