I understand the basics concept of how the moving average convergence/divergence is derived. I also understand the relationship between MACD and the MACD EMA. What I do not understand is the relationship the MACD and MACD EMA lines have with the divergence. For instance, what difference does it make in the diagram of MSFT whether or not the MACD and MACD EMA lines are above or below the 0 divergence line? Anyone able to help me out on this one?
