Alarm

[jed77]

Hello there !

I want to put a sound alarm on a set of conditions in my indicator.
My indicator is "real time", not calculated at bar close.

How can I setup my sound alarm to play only the first time the conditions are met and not at each ticks ?

Thank you very much.

Hi jed77, you could use FirstTickOfBar() to generate it only then and not on subsequent ticks in that bar, see this link here please - http://www.ninjatrader-support.com/H...TickOfBar.html

Alternativelt you can also set the rearm setting to a higher number - http://www.ninjatrader-support.com/H...eV6/Alert.html

Yes, but sometime, conditions are met "intra bar" not at the 1st tick...
How can I handle that ?
Thx

Ok, did you try using a higher rearm setting then?

[jed77]

No, not yet, was trying to investigate if there's a better solution....
Keeping that as "Plan B"

Hi jed77, more elegant way would be to program it manually. You could reset a variable on the first tick of the new bar and record then if your alert condition has triggered.

HoHo !
That sounds good !
This is the idea I had in mind, but I don't really know how to do....
Thx

Hi jed77, ok here is some sample code that would do this. Remember you need a unique alert id for this to work. Please put the variable

private bool myAlert = false;

in your Variables() section.

This is the OnBarUpdate() then -
