MACD

Overview of the Moving Average Convergence Divergence indicator.

The moving average convergence/divergence (MACD) is a technical indicator of momentum that uses moving averages to determine a trend’s strength. The MACD uses three exponential moving averages (a short term, a long term, and the average difference between the short and long term) to show price momentum.
