# AaveV3QuotePriceRangeTrigger

## Description

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

{% hint style="info" %}
Notes

* The contract computes the base/quote ratio by dividing the oracle prices of the two tokens.
* 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`.
* Checks Aave V3 oracle for current prices and triggers if it's in a correct state.
