Hello Graham,
Unfortunately i have also noted that there are some bad things if
multiple alerts are used.
I have contacted the amibroker support last week. Below is the reply
from Marcin.
Basically it means that NOT every alertif is separate !!!
I have suggested them that they make it separate. This would make it
much easier and more comfortable.
My idea was to get only one alert per bar and get this alert per email
and per sound.
So i have firstly used only accoustic and than only email alert and
both worked well. But when i used both there are troubles.
See the description from Marcin.

Hello,
Indeed - that's possible because it works the following way:
Once Alert (1) is triggered, any further alert of a type (1) - 'buy'
can be repeated, because
4+8 flags prevent it.
However - then - with the new refresh, the other alertIf() function
detects, that the most recently triggered alert was type (1),
so any other type of alert is allowed - so alert (2) gets initiated,
and - once formula is rereshed once again,
that happens once again, now for alert (1) type.
So - you should write your trigger conditions that way, that does not
allow several alerts of a different type on the same bar,
because it will lead to such situation.
On the other hand - if you have two alerts of (1) type defined in the
formula, once the first one is triggered,
the other one cannot, because by using 4+8 flags you do not allow 2
alerts of the same type.
Best regards

Subject: Re: [#23662] alertif problem
Hello,
i have made a lot of tests now and indeed the problem occours when i
use the email and accoustic alert at the same time !
When i only use the accoustic or mail alert it works as it should.
Furthermore when i use the same alert type (buy) and both alerts than i
only get the accoustic alert once per bar.
AlertIf(1,"SOUND C:\\Windows\\Media\\Alert.wav", "Indicator left Low
level",1,4+8,1);
AlertIf(1,"EMAIL", "A sample alert on",1,4+8,1);
When i use the code below (buy for accoustic alert and sell for mail
alert)
i get continously mails (every new tick).
AlertIf(1,"SOUND C:\\Windows\\Media\\Alert.wav", "Indicator left Low
level",1,4+8,1);
AlertIf(1,"EMAIL", "A sample alert on",2,4+8,1);

I noticed this behaviour from an AA window alert with 2 alertif
statements that had signal at same time. At that time I was testing
email alerts and at same time the other alert was for sounds.
Individually both worked, however with both enabled the AFL locked up
and no signals were received.

Graham,
Have you noticed if the interference between 2 alerts can happen from 2
different indicators, or is it only when 2 alerts trigger on same bar in one
indicator?

Graham,
You have made an Interesting obdervation!!!
Seems once two Alertif() statements "collide", something gets corrupted
and
they will not function even individually. I will do more testing with
single statements.
Is anyone using Alertif() succesfully ... or have given up ?
I spent a lot of time trying to make Alertif() work about a year ago ...
and
decided to try it again. It would be a shame to give up such a useful
feature ...
I assume the flags I have coded are correct for keeping trigger active
repeatedly
Hope this gets resolved, because i can REALLY use this feature for real
time trading

I have found that 2 or more alertif that trigger at same bar stop all
signals. They seem to interfere with each other

Having problems with alert if....
The 2nd alertif code below works (most of the time). By most of the
time
I
mean it works at specific points on the chart, and not at others
meeting
the
same criteria.
The 1st alertif code, has less strict criteria, uses the same sound
file,
but never works.
I have coded the flags (or at least I think so) to trigger every
time
Appreciate any help
