How do I add custom indicators to condition wizard?

Two things. When you see this error: “rec usage is not allowed in this context” it means the code cannot be used for Study Alerts or for Conditional Orders. There is no workaround. When you see this error: “Error processing referenced script XXX: No such function: XXX at 1:1 Expected double at 1:14” It means you are trying to reference a custom study instead of copy/pasting the entire code. You cannot reference a custom study the way you can a built-in study. The only workaround is to include the entire code. But if you get the “rec usage” error while doing that you still have no work around.
