Continuous alarm that can be turned off

Hey there,
I am trying to write an alarm that will sound continuously when a condition has been met. The only time that it will stop, is when the user will turn it off. Now, writing the part with the continuous alarm is easy, but my trouble is: How do you allow user interaction to stop the alarm from sounding. Of course disabling the indicator is not a solution. I have searched everywhere and I have not been able to find code anywhere that allows user interaction to stop a process such as an alarm.

Could anyone please help me? I really did not think this would be so difficult.

Thanks!

First I must caution you that I have never tried this myself, so there may be something simpler to accomplish what you want to do. I will not supply any code to do this, so that part is yours.

I would create a label on the chart called something like "Alarm". This should be done in the Init() function using ObjectCreate() and given an initial value of "On". Once the alert is triggered, it should check the value of the label using ObjectGet() to see if it has been changed to "Off".

You as the human would change the value to "Off" or "On" as required, using Objects List.

Use a global variable to enable/disable the alarm.

When you want to switch it off, run a script to change the value of the g variable. If you name the script "DisableAlarm" it should be simple to identify.

This is quite a good approach, but it doesn't need the script. Use F3 to access the Globals table and change the value manually.

This is my first doing something like this, but I just gave it a shot anyway. Btw this is an EA.

There are 2 extern variables:
playsound1
When this is set to true, it will play the alert sound as indicated by "soundfilename1" repeatedly until the user stops it.

soundfilename1
This refers to the alert sound filename, I strongly suggest you change it to the name of your preferred alert music sound (Unless you're ok with the "alert.wav", it makes me want to smash my keyboard...). You can place additional sound files in your "<MT4 Broker name>/sounds" folder.

To simulate a user input to stop the alarm from sounding off, double-click on the "Alarm On" Label, drag it around the screen to any position, then release it. It will then switch to "Alarm Off" mode, the text color will change to red and will stop the alerts from sounding off.

Similarly to start it up again. Just drag and drop the "Alarm Off" Label to any position on the screen and it will start sounding off again.


Not sure if that is completely what you want, but feel free to make the changes as you like.

Hello Guys.... I have a simple MA cross indie that rings when the price closes on the other side of an MA. The code you guys came up with here to turn it on and off would be perfect.

I run this across 15 to 20 pairs at a time. Sometimes the price on some pairs is just ranging back and forth causing the alarm to ring after every bar.

The perfect solution is to have a simple way to turn the alarm on and off with a display on the chart to indicate whether it is active. Looks just like what you've done here.

If anyone would like to add that feature to this alarm indie it would be much appreciated. As you can see from the code, it's a fairly simple indicator. I just haven't attempted coding yet.

Hi price,

Here's your version. To turn it off, double click on the label then move it to any other position. And it will say on screen "Alarm Off" in red. Do the same again to toggle it back on.
