Hi Thomas,
I think that the solution now is
that you have to prioritize alerts so that only one can fire (and perhaps
complete) at any one time. I received some info from Hermann on this
board some time ago, lost the link so I can’t send it. It was
before my message #82061. His solution involved prioritizing the alerts
so that there was no interference. At the time that I looked at it, it looked
like more work than I wanted to devote to it.
At some time back there TJ described the
implementation of the alertif which gave some insight on how it works. You
should be able to find all that discussion, there have been boatloads of messages
on the subject.
For the solution in the future, my
personal view, as a non-programmer, is that the implementation of the function
should be improved. For the time being it provides the basic
functionality, but as we look at AB becoming more and more capable, this is one
of the items to add to the To Do list. I have not sent in a request
myself since I saw various others commenting on the problem. TJ will have
to assess what priority to assign.
Best regards,
Grover

- Windows???
Hi Grover,
i also have problems when i use two alerts simultaneously.
However i don't see any trick to solve it, because i have for example the level
20 on my indicator for alert.
Now when the indicator crosses this level i want to get an email and accoustic
alert only once per bar and i have a 60min interval.
Is there any way to solve this ? If yes, i would search all the messages.
Regards
Thomas

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.

Spoke too soon ... My multiple alerts are back ...

Alertif() - Windows???
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.
