Complex pairs1 - Adding change of colour

 

Hi all coders!
Can anyone help me with this coding:
The line has now only one colour. I would like it to have two col instead.
Blue when present value is higher (going up) than previous, and red when it´s lower(going down).
I have tried to read and understand the code of other 2-coloured indies, but I haven´t managed to make it right.
Probably piece-of-cake for you coders out there.
Any help much appreciated.
