I have had an alert set on a horizontal line on a volume study that's supposed to trigger when volume exceeds a certain volume. The the alert has triggered only once out of 11 instances. It is set to trigger once per bar.
PS: The alert has been on the line for several months.

Is the Horizontal Line actually drawn in the region where the Volume study is?

When you go to the Alert options for the line, do you see only the option for "Volume" in the "Study Subgraph" section?

It's in the study. It has rung twice correctly since I made this post but this morning it rang once out of 40 occurrences.

We are not seeing any issues with the alert on a Horizontal Line put in the same region as the Volume Study.

Please get us that chart that has the line in it so we can take a look and see if we can reproduce this and determine what is occurring. Follow these instructions to get us the chart:

Chartbook is attached. Three charts were necessary.

FYI It worked on the 9:30 bar but didn't on the 9:35 bar.

The issue is that you are using a condition of "Cross From Below". This kind of condition looks at the prior value when determining if a crossing situation is occurring, as the prior value needs to be below the set value, which would not be the case for any subsequent bars that cross the line.

Use a condition of "Above" and it will give you what you want.
