Android - Push Notification in Background Service c#

Question

I am working on Android C# app which tracks user's stocks price. I want the app to push notification (in background) whenever the value of stock increase 1%. I have searched online and I know I need to use BroadcastReceiver and Services but I am not able to implement my own code and I haven't found a tutorial or a published exemple on how to do it. I am sure the solution will be very easy but Ia m not able to get it. So again, I want to push notification in bachground whenever the var price goes up by 1%.. Please Help me to do so.. Thank you

Here's what I have till now:

     [BroadcastReceiver]
public class MyReciver : Android.Content.BroadcastReceiver
{
    public override void OnReceive(Context context, Intent intent)
    {

    }
}
