Yes, change flag parameter to
zero.

Windows???
Hello Tomasz,
Thank you very much !
Works fine now
and i'm really very happy !!
Just one last question, is it possible to
select "no text in alert output" ?
I have added an email and accoustic
alert now,
but i only want to see one alert line in the output window
because both alerts are exactly the same. (same alert condition)

Hello,
OK, my mistake, I have written it right off
hand. You need to wrap StaticVarGet with Nz
function to make sure that if variable is not
set at all Null is converted to zero:
YourCondition = 1;//...
lastdatetime = LastValue(
DateTime() );
if( LastValue( YourCondition )
AND lastdatetime >
Nz(StaticVarGet( "AlertFlag2"+Name() ) ) )
{
// update static variable
StaticVarSet( "AlertFlag2"+Name(), Lastdatetime );
// as many alertif
statements as you wish
AlertIf( True, "EMAIL ...", "Text", 0, 1
);
AlertIf( True, "SOUND ...", "Text", 0,
1 );
}

Hello Tomasz,
i have tried your script now. I have
also checked "Start" and "End" time of interval as you have
written.
However i do not get any alert, whether acoustic nor
mail.
YourCondition = 1;//...
lastdatetime =
LastValue(
DateTime() );
if(
LastValue(
YourCondition )
AND lastdatetime >
StaticVarGet(
"AlertFlag"+Name() ) )
{
// update static variable
StaticVarSet( "AlertFlag"+Name(), Lastdatetime );
// as many alertif
statements as you wish
AlertIf(
True,
"EMAIL ...",
"Text", 0, 1 );
AlertIf(
True,
"SOUND ...",
"Text", 0, 1 );
}

Hello,
Yes it works once per bar. Make sure to set
either "START time of interval" or "END time of interval"
in Tools->Preferences->Intraday
page.
Other settings will result in multiple
alerts per bar.

If yes, i would

Hello,
There was a missing brace in the
sample code, corrected is:
YourCondition = 1;//...
lastdatetime =
LastValue( DateTime() );
if( LastValue( YourCondition )

{
// update
static variable

Re: [amibroker] Alertif() - Windows???
Hello,
If you want to have both sound and
e-mail or anything else it is quite easy to implement
NOW
once per bar using StaticVariables,
a sample code would look like this:
YourCondition = ...
lastdatetime =
LastValue(
DateTime() );
if( LastValue( YourCondition )
AND lastdatetime
> StaticVarGet( "AlertFlag"+Name() )
{
// update
static variable
StaticVarSet(
"AlertFlag"+Name(), Lastdatetime );
// as many
alertif statements as you wish
AlertIf( True,
"EMAIL ...", "Text", 0, 1 );
AlertIf(
True, "SOUND
...", "Text", 0, 1 );
}

Re: [amibroker] Alertif() - Windows???
Hello Grover,
i fully agree with you,
the function has to be improved or corrected. I have searched
the archive now but found no solution.
Ok, have to
prioritize alerts, sounds good, but found no information on
how to do that. Other informations i have found are that
alerts should be written so that they not occur at the same
time. In my opinion this is also no solution. If i would like
to buy at any condition than this is my condition and not any
other condition. So now i stop trying the alertif function
until any update is available. It's a pity that we can not
really use it as we all would like to use it.

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
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.

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.
Grover
Spoke too soon
... My multiple alerts are back ... this is
frustrating!!! not sure I'll be able to use the
feature if this
continues..

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.
