Hello!

I'd like to modify the "TMA+CG NRP" indicator, see attached.
I would like the centre line of the channel to change color based on it's direction. 
Basically i would like the centre line in the channel to change color based on it's slope.

If the centre line slope is positive i'd like it to show a user defined color (ex: green)
If the centre line slope is negative i'd like it to show another user defined color (ex: red)

Please add below stated inputs to the indicator

"SlopeColorPositive = #"
"SlopeColorNegative = #"

Best Regards,
Megasek.
