# LOAD_FAILED

Running the top level of the file raised an error.

## What happened

Loading a file runs the top level of it once. When that raises an error, the file cannot be used. The message is the error's own name and text.

## What to do

Fix the error the message names. Keep what runs at the top level of the file short and free of anything that can fail.

## Example

```text
strategy.py, line 9: NameError: name 'slow_period' is not defined [LOAD_FAILED]
```

The wording of the message depends on your file, and the code does not. An error stops the file from loading.
