Signal Line

DEFINITION of 'Signal Line'

A moving average plotted alongside a technical indicator and is used to create transaction signals. Buy signals are generally created when the indicator crosses above the signal line, while sell signals are generated when the indicator crosses below it.

A signal line is also commonly known as a "trigger line."

BREAKING DOWN 'Signal Line'

The MACD indicator and the stochastics oscillator are the two most popular tools used in technical analysis that generate transaction signals by using a signal line. Most trigger lines are created by using a three- to nine-period moving average of the indicator values.
