Add alert to indicator

[bentekkers]

So i have this indicator which I have found to be very good at identifying trending periods, to stay out of the market. However, it does not have any alerts which makes tracking it hard. It would be much appreciated if someone could help me to add a push alert when the purple line goes above the top blue line or below the bottom blue line. I have found it works best when the alert is sent only immediately after the candle has closed, as the signal is most accurate at that point.

Cheers
