How do i create a way to see the smooth acceleration of a sma(200) in an easy and right way? 

My strategy relies on when the SMA starts to gain or loose momentum. 

My problem is that when I use the MOM on SMA I get a very noisy graph is there a clever way to make it less noisy? preferebly totaly smooth. I don't really wanna take the mooving average of it. 
I guess the best way would be to noise filter/ smoothing the SMA(200) first and then get the mom of the smooth SMA? Is there a SMOOTH() or NoiseFilter() method?
I guess I can always use a filtering method for numpy arrray. but its just a hassle. 
i attached the back test.  thanks for any advice :) 

kind regards martin.
