How to measure the red line of the MACD

 
It is written nearly everywhere that the red line of the macd is the EMA12, but when i compare the redline and the EMA 12 in mt4 it is not the same...
How can i create this line and measure it in an Indicator?
Thanks, Lisa!

Hi dear,

The redline or Signal line is not EMA 12. It is SMA9 in default if you set the MACD 12-26-9
