can any one help me and bring me gaussian filter

New comment
 

hello every one

i'm enterested in mostafa belkhyate

and i hear that he is using center of gravity and the timing indicator

recently i dicoverd that he was using something called (( gausian filter )))

can any one help me and bring me this (( gausian filter )) and tell me please how it work

 
sorry it's name is (( gaussian filter ))
 
is there's no one could help me ????
 

Hi, i am going to publish a few indicators with gaussian filtering.

Here is the basic filter:
