About this app

Distributes each session’s volume across the price bins its range covers rather than dumping it at the close, builds a horizontal histogram beside the price line, and expands outward from the busiest price until a chosen share of volume is enclosed. Marks point of control, value area high and low, and names the thin shelves where little changed hands. States the limitation directly: daily bars give a good approximation of the shape and a poor one of the detail.
