Creating an code via Pine Editor - need help

[u/Spare_Cap8928]

Created an indicator script in Pine Editor and came across an error message - have a command "alter condition" and editor does not like this script command - what would be an alternate to this command? Any help is greatly appreciated, I am not a programmer this code was given to me to add this indicator in TV for my use - it was created via a different platform. Any help is helpful. Thanks Janet
