Thanks Wavemechanic
I have uncommented those lines and now my chart looks terrific.
So that is first question sorted- and thank you again.
Now I would like to learn more about plotting text within the formula.
I looked at Plot Text function and tried the MACD example.
I also tried to understand the formula below -
which would be near to what I want.

But, I am totally lost as to how to code the text I want and have it
over the top or bottom of each swing on the Gann chart.
DATE
Close
Range
Days
If anyone has some time to guide me would be a relief.
Cheers Raine
