Re: [amibroker] Alertif() - Windows???, AmiBroker Email List Archive

Ara,

Your comment that multiple triggers from a program with a single alert is interesting. Could this be because an alert message has not finished its processing (e.g. a spoken alert message) before a new trigger for the same message comes in?

In any event, I agree that trading in real time could be enhanced with more than a single alert.

Grover, Terry,

Thanks for your responses...

I have prioritized the alerts, but it's impossible to insure that only one alert triggers based on priorities because I use multiple time frames (same code in separate indicators).

I have written to support about it, but no response yet (2 days .. so I suppose I will get a response soon)

I also get multiple triggers when a program with a single alert triggers multiple times, when my other program with multiple alerts is not triggering .

So I hope TJ find the time to address the problem ... Trading in real time requires more than a single alert

Hi Ara,

I am pasting from my message 82061 which was a message to a fellow user:

“I have had similar experiences, more than one under a variety of conditions. The common “denominator” which causes the problem is when one alert triggers simultaneously with another. When that occurs it causes AB to display the error message which you quoted stating that you need double back slashes (even though you have double back slashes in your program), and then the program gets into a loop and continues to repeat the alert. The workaround which I got in a message from Hermann is to prioritize your alerts so that only one can fire at any one time. I have had similar experiences, more than one under a variety of conditions.”

The solution with the present system as stated above is to program such that no two alerts can be triggered simultaneously. I worked on it for a while with some excellent info from Hermann, but turned to other objectives before getting it smoothly working.

I believe that if one has only one alertif statement in his code, then by definition, no two alerts can occur simultaneously. If you have more than one alertif, then you need to prioritize in some way.

You can search the archives for a lot of traffic on this.

Hope this helps.

I just had a strange behavior ...

One of my alerts kept repeating continiously ... the control values are set correctly to ... 0,12,1).

I rebooted PC and problem cleared!.. I assume the problem was not with Amibroker ... but I have heard other complain of same issue.

I have no idea why or how this problem occured, but I would like to suggest that if anyone finds programs that may cause problems, please share your experience... WINDOWS of course is always my prime suspect ... but would be nice to be aware of other problem programs.
