Algorithmic Trading can be a complex subject. Keep your knowledge current with this glossary of key concepts, terminology, and technical indicators.
A price zone in which a stock finds support and begins to trade upward once again. In technical analysis, support occurs not at a finite point, but in a zone. The "density" of the zone of support (how far the price can move down through it) depends on the volume of trading as the price approaches and enters the zone. The higher the volume of trading in the zone of support, the higher the point at which actual support will most likely occur.
