MACD indicator (Moving Average Convergence/Divergence)




 The MACD indicator is one of the most popular oscillators, developed by renowned trader and analyst Gerald Appel. "Moving Average Convergence/Divergence (MACD)" translates as "convergence and divergence of moving averages". As the name implies, MACD uses a combination of several movings with different parameters.


The indicator is calculated in a separate window on the terminal screen and consists of two lines, one of which is represented as a bar chart. The trading signal is the intersection of these two lines, as well as divergence (divergence) - the discrepancy between the extreme values ​​of the indicator (highs and lows) with the price chart. Divergence can predict an incipient correction or even a trend reversal.
