Row — · auto
Zoomed out it is a normal chart with buying (green) and selling (red) volume, and under it the delta: green bars when buyers outweighed sellers, red when sellers did. Zoom in and every candle opens to show, price by price, how much was sold (left) and bought (right). Drag to move, scroll or pinch to zoom, scroll on the price scale to stretch it, double-click to fit.
