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.

The UV spectral observations showed that absorption lines from aluminum, tin, manganese, among other elements became more pronounced as the planet transited the star, meaning that these elements exist in the planet's atmosphere as well as the star's.
