Alert only triggered once per Bar

[laocoon]

Hi,

I've developed an alert that's triggered while a bar is still in progress (CalculateOnBarClose = false), but if it is triggered I want to make sure it can't be triggered again within the same bar. How can this be achieved?

Thanks

Hello laocoon,

Thanks for your post.

You can check to see if the current bar is the same bar as the alert was issued on. For example assume you create a private int alertBar and then save the CurrentBar into it when you set the alert:

if (your alert conditions && CurrentBar != alertBar)
{
Alert(...);
alertBar = CurrentBar; // save the current bar on the first time through
}

So in the example if the current bar is not equal to the alertBar then the alert will sound and the current bar number will be saved into alertBar, on the next tick(s) the alert will not be issued until a new bar is opened and CurrentBar changes.
