QQE indicator popup alert needed

Could someone add a popup alert when the blue and red lines cross

Thank you

It is already done. Just look here and there, use google and you will find. There are several versions, with and without messagebox, email etc.

One of my students recommended this site …

so this is my first post and I’m looking forward to being a regular …

It seems that the student has something to teach to the master ! You find the right place.
