# BAD_ATTRIBUTE

symbols, direction, order_mode or warmup has a value Forge does not accept.

## What happened

`symbols`, `direction`, `order_mode` or `warmup` has a value Forge does not accept. `symbols` is a list of 1 to 50 symbol names, `direction` is long, short or both, `order_mode` is managed or unmanaged, and `warmup` is a whole number of bars.

## What to do

Change the value to one of those.

## Example

```text
strategy.py, line 9: direction must be "long", "short" or "both" [BAD_ATTRIBUTE]
```
