1. In technical analysis, a situation in which the supply and demand for a security are largely the same. A line means that the security is unlikely to see any rapid fluctuation in price. It is called a line because, when plotted on a graph, it looks like a roughly horizontal line. Technical analysts look for signals that a line is ready to break one way or another before recommending that investors take a position on a security.

2. Informal; workers in a large, industrial company. They are called the line because, historically, they assembled the parts of a product while literally standing next to each other in a long line, also called an assembly line.


In technical analysis, a horizontal pattern on a price chart indicating a period during which supply and demand for a security are relatively equal. Technical analysts generally look for the price to break away from the line, at which time they are likely to take a position in the direction of the movement. See also making a line.
