How to add Moving Avg to MACD?

Beginner Questions
1

In the school program the MACD had 2 lines (blue and red) which acted like moving averages, and cross over one another every once in a while.

But on my MT4 there is only one red dotted line, and I can’t seem to find/add another one.

How can I add it? Is it a separate add-on? I use Mac OS

You have to look for a custom MACD as the one provided by MT4 is a POS just like MT4 is. The one you have is useless.
