I was looking for a way to have my phone call me with an alert for when a level is crossed during Globex, when I am asleep. Not a popup on my phone, but an actual phone call instead. Well, I just found out it's possible with this provider (no affiliation): https://www.callhook.pro/

Just right-click your chart where you normally set up the alerts, add a webhook for these guys, and get alert calls. Cheap too.

Interesting.

It's been coming in handy. Not just for Globex levels at night, but other times too. During trading as well as stalking levels. So I don't have to stay in the room or keep staring at the screen. It lets me know when it's crossed levels.
