Hello,
I am trying to implement a Point of Control value into a custom strategy. There has been an indicator created by another forum called SimplePOC. This indicator functions fine as an indicator, however, if I try to reference it in a strategy it throws an error, saying the color is not defined and also that the color is acting as a variable. Is there any way I can resolve this?
Code below for the original SimplePOC indicator.
thanks,
Nick
