Price checker action works in tandem with program condition triggered automations. It allows you to specify a price condition before the automation is allowed to execute.
For example, you can create an automation that performs a swap when certain price conditions becomes true, like so.
Price checker action uses Pyth price oracle for price data which is updated frequently. Please check with Pyth Network team for the specific frequency.
It is also possible to add multiple price conditions simply by adding multiple price checker actions in the same automation flow.
