# CompV3PriceRangeTrigger

### Description

Trigger contract that verifies if current token price ratio is outside of given range specified during subscription

> **Notes**
>
> This uses the CompoundV3 oracle, which returns the price of the collateral token in terms of the base (debt) token. The trigger expects the lowerPrice and upperPrice inputs to be scaled by 1e8. It is possible to check only one side of the range by setting the other side price to 0.

const compV3PriceRangeTrigger = new dfs.triggers.CompV3PriceRangeTrigger(

### Subscription Parameters

## 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.defisaver.com/triggers/compoundv3/compv3pricerangetrigger.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.
