Vertical Lines Peaks Alerts

[baTrader]

I've tried many different ways to get alerts to trigger on OSpeakTrigger and OBpeakTrigger but have been unsuccessful. I feel like I must be missing something. Obviously I'm getting the verticals, so obviously the condition is true, but the alert isn't audible. Seems it may have something to do with the parameter SlowK[-1]. Can someone please help me? Is there a fix for this? Thanks!

Yes, you are correct, the culprit is:

SlowK[-1]

Your code is looking if the current bar is lesser (or is greater) than the bar that occurs next.
The bar that occurs next after the current bar has not happened yet.
So your script does not work in real time. If waits until the future and then goes back in time and repaints a vertical line.

Alerts are real time. Repainted verticals are not.
You can attempt to go back in time and capture the alert by changing:

Alert(useAlert and OSpeakTrigger
Alert(useAlert and OBpeakTrigger

to:

Alert(useAlert and OSpeakTrigger within 3 bars
Alert(useAlert and OBpeakTrigger within 3 bars

Most scalpers will not use future bar repainting scripts such as this one, because the 2-3 bars delay in alerting is not profitable.

Tried that but it didn't work. Any other way to potentially get that alert, or identify the peak without using SlowK[-1]? Thanks

As explained before, attempting to scan, watchlist, or alert on repainters is an exercise in futility.
No, the essence of the script relies on the future bars: SlowK[-1].
The future bars are why the script looks so deceptively perfect.
