Change the status of orders automatically

I need to change the status of my orders to (Cancelled) automatically after 7 days if it is not processed.

I need to change the status from: New Request to Cancelled. Or I need to change the status from: Processing to Cancelled.

Thanks Adnan

I did that with the help of this code:

function autocancel_wc_orders(){
    $query = ( array(
        'limit'   => 10,
        'orderby' => 'date',
        'order'   => 'DESC',
        'status'  => array( 'wc-pending', 'wc-ywraq-new', 'wc-ywraq- 
        pending')
    ) );
    $orders = wc_get_orders( $query );
    foreach( $orders as $order ){       

        $date     = new DateTime( $order->get_date_created() );
        $today    = new DateTime();
        $interval = $date->diff($today);

        $datediff = $interval->format('%a');

        if( $datediff > 2 ){
            $order->update_status('cancelled', 'Cancelled for missing 
            payment');
        }   
    }
} 
add_action( 'admin_init', 'autocancel_wc_orders' );
