RUN_SETTING_IN_CODE
What happened
Run settings such as the starting balance belong to a run, not to the file. A class attribute with one of those names changes nothing, because the Tester sets its own value for each run.
What to do
Remove the attribute. To suggest a value, put it in defaults.
Example
text
strategy.py, line 6: `initial_capital` does not change the starting balance: the Tester sets that for each run. To suggest a value, use defaults = {...}. [RUN_SETTING_IN_CODE]The wording of the message depends on your file, and the code does not. A warning does not stop the file from loading.
