Julia Waller, the condition for buy and sell must be in the main loop, also that indicator recalculates(repaints) so alerts on it are going to be very misleading.

Hi, I was trying to figure out how to make a sound alert for the indicator i-Regression Channel (code attached), but I can't make it functional.
I wanted it to sound an alert everytime the price crosses the lines (from any direction) excluding the middle one.
Can anyone help me?
Thanks in advance.
