That can cause staircase ramps but in this case sales volume had spikes at the ramp areas.SNE is just an ADR. It has staircase ramps because the price is based around the price of the actual stock that is traded in Tokyo combined with the price of the Yen.
I originally posted a chart from my stock broker that had the sales volume information in addition to the sales price chart but it stopped displaying.
