Algorithmic Trading can be a complex subject. Keep your knowledge current with this glossary of key concepts, terminology, and technical indicators.
A technical trading pattern in which a security's value ranges between two horizontal price points, creating a rectangle on a trader's screen. Rectangles occur in situations where a security is consistently bought up, when a lower price value is established, and sold down, when an upper value is similarly established. These price values remain "hard" values for a definite period, which is what creates the rectangular pattern.
