WRONG_KIND
What happened
The file defines an indicator where a strategy or a library was expected, for example an indicator file given to a place that loads strategies.
What to do
Use the file where indicators are loaded, or write a strategy class instead.
Example
text
strategy.py, line 5: `Trend` is an indicator. Only strategies and libraries load here. [WRONG_KIND]The wording of the message depends on your file, and the code does not. An error stops the file from loading.
