Thank you

MACD line is a difference between a Slow MA and Fast MA. We have a MA Crossover signal when MACD Line crosses the zero line.

For example, if we want long signal when the Fast MA crosses the Slow MA upwards (a begging of a bull trend), we can use MACD with a logic rule "MACD line crosses the Zero line upward". I'll illustrate this with the following reversal strategy:

I use Moving Averages only to show that the MACD Line (MetaTrader plots it as a histogram ) crosses the zero line at the points where Fast MA crosses the Slow MA. You can remove the MA indicators because they are only for demonstration.

We can use only Exponential moving average because MetaTrader doesn't provide options for setting the MA calculation method.
