Convert a MT4 indicator to MT5 with source code

I have an MT4 indicator (SW TRIX) that I would  like to get converted to MT5. 

I would like the source code with the final solution. 

I will provide the full indicator when we have our communication about the project.

I am looking for someone with experience in these conversions.  Thank you.

===========================================

Here is a snippet of the code:

   2009.07.18 - 4 colours
