# Pricing Anomaly Warning

## Pricing Anomaly Warning

The "Pricing Anomaly" warning appears when a trade opportunity's pricing is outside an expected range. This typically occurs when an option leg is lacking a bid or the bid-ask spread for one leg is inverted with another leg.

For example, the strike closer to the money has a mid/mark price that is less than the leg further out-of-the-money.

You should reference your broker platform's option chain to investigate and check for zero-bid and inverted bid-ask spreads if you receive this warning.

Note that bots reference pricing at the time the order is submitted, so there could be situations where pricing for a particular leg fluctuates faster than what is displayed on the broker's platform.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.optionalpha.com/technical-documentation/troubleshooting/pricing-anomaly-warning.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
