ATR Study

[Harndog]

Hi:
I am wondering if Alex can help me with creating a study.
Attached is a chart of the built in ATR Study. I am looking to create an alert or non-price study when the ATR goes below or above a certain level. It would be nice to the ATR length adjustable along with the parameters for the levels.
I did a search for the ATR and attempted to use the Formula wizard but am confused on how to have a formula reference a certain level in a non price study.
Attached is the ATR chart and if you could build this study I would appreciate it.

The attached efs should do what you asked and provide you enough of a working base for you to add your own conditions/actions.

I omitted to add the bands in the efs. To include them insert the following two lines in main()
addBand(Upper,PS_SOLID,1,Color.black,"upper");
addBand(Lower,PS_SOLID,1,Color.black,"lower");
The default values for Upper and Lower are set at 1 and 0.65 and can be modified through Edit Studies.

Note: I have also updated the efs at the original link to include the bands

The original link contains the updated efs.
As to your revision the problem is caused by having added those commands in the brackets of main().
By saying insert the lines in main() I meant anywhere in between function main(){ and the very last } that closes the main function
Not sure I explained this in the best of ways, perhaps someone else may want to chime in.
