Color Change 9ema on a $TICK chart

[QED]

I understand how to add a moving average to a $TICK chart (duh), but I do not know how to code a 9ema that is green when it is above the zero line and red when it is below the zero line on a 5 minute $TICK chart. I use the moving average to help identify the general short term market trend.

I searched this site, but did not find what I am looking for. If anyone could help with this it would be appreciated.

AssignValueColor() is the function that you are looking for.
Here is the syntax:

FYI, when making posts about changes to your script.
Best practice is to include your complete code, so contributors can provide a complete code in return.
