The MACD indicator in MetaTrader 4/ differs from comparable indicators in other programs. This is a result of the fact that in the model of MetaTrader 4/, the MACD line is displayed as a histogram, whereas traditionally it’s displayed as a line. also, in the model of MetaTrader 4/, the signal line is built utilizing SMA, whereas by definition it should be built utilizing EMA. In the version of MetaTrader 4/, the histogram can also be distinct (the difference between the MACD line and the signal line). This may be unusual for newcomers to using MetaTrader 4/5, since the MACD line itself is displayed as a histogram, and the real MACD histogram is not available.

This indicator displays the MACD as it was conceived by the author (Gerald Appel) and as it is shown in other similar programs. The MACD line is calculated as the difference between the fast and slow EMA. The signal line is the EMA from the MACD line. The MACD histogram represents the difference between the MACD line and the signal line (the MACD histogram itself can be used to get divergence signals).

The True/False switches allow you to display / hide the MACD line, signal line, and histogram.
