# Moving Average Convergence/Divergence

## Description

The Moving Average Convergence/Divergence is a trend-following momentum indicator that shows the relationship between two moving averages of a security’s price. The MACD is calculated by subtracting the 26-period Exponential Moving Average (EMA) from the 12-period EMA. The result of that calculation is the MACD line. A nine-day EMA of the MACD, called the "signal line", is then plotted on top of the MACD line which can function as a trigger for buy and sell signals.[1]
