# HOOK_FAILED

A hook raised an error during the run.

## What happened

A hook of your strategy raised an error while the test ran. A hook that raises ends the run. The error is kept on the result with this code, the file, the line and the bar it happened on.

## What to do

Open your file at the line the message names and fix the error in that hook.

## Example

```text
strategy.py, line 31, in on_bar: on_bar raised KeyError: 'atr' [HOOK_FAILED]
```

The wording of the message depends on your file, and the code does not.
