# What does "24h" change mean?
### **(C) 24h Change**
Price change refers to the price movement of the underlying asset over the past 24 hours.
In Tradoor, this is reflected in a percentage change, which shows how much the index price has increased or decreased compared to the price 24 hours ago, expressed as a percentage.
Keep an eye on this, as it helps traders gauge the recent volatility and trend direction.

## 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.tradoor.io/tradoor-user-guide-v2/how-to-trade-on-tradoor/trading-perps-101/how-to-navigate-tradoors-perps-trading-page/what-does-24h-change-mean.md?ask=&goal=
```
`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.
