[STUDY] MACD. Part 3 Signal Line (Comparison of moving averages)

This is my research into the behavior of different moving average calculations to different aspects of the MACD. The MACD consists of three parts:

• 1. The MACD (moving average convergence/divergence of the fast moving average period 12 versus the slower moving average period 26)
  
• 2. The signal line (moving average period 9) of the MACD
  
• 3. The histogram of the MACD (difference between MACD and the signal line)
  

This is part three of my research which only shows the signal line of the purely WMA / EMA / SMA based MACD.

Here is part one, the histogram of the MACD:

And here you can find part two, the original MACD itself:
