Directional efficiency (DE) is a new concept that has a geometric and economic form involving fractal properties of a price path. They are complementary. The DE varies from 0 to 1. Geometrically, two arbitrary ticks on a price chart are the ends of a straight-line segment. The interval of the ticks is the shortest path between two events. If the latter are not time neighbors, then intermediate events constitute an interval-wise path connecting the two events. In general, it is longer than the interval. Geometric directional efficiency (GDE) of an interval is the ratio of the lengths of the interval to the path. If ticks are on a straight line, then GDE is equal to one irrespective of scaling. Otherwise, it is less than one and greater than zero.
