Hello to the advanced coders here in FF

I added a playsound() to an indicator and it workes quiete well but it get me on my nerves because it gives a sound every tick for two candles.

What I can do to let it sound only onces or twices?

Sorry if that was explained somewhere before but I'm now 4 hours searching and coundn't find a solution.

Please explain it in easy language, I'm not a coder but can help myself a bit.

Thanks in advance

If you are using it as an alert and only want it to sound once when a if(..) is true, the way I do that is to put this in the top area with the external variables
datetime once = 0;

then in your if statement you would say

if( your logic && once != Time[0] ) or Time[i] if it is in a loop using i
{
Playsound
once = Time[0] or Time[i] if in a loop using i
}

This will only play once for that bar. if the your logic is true.

If this does not satisfy your requirements. Please post your code and a more clear explanation of what you want and I or someone else would be happy to take a look.

Thank you very much for the quick response.

I'm posting here the indicator, would be nice if you could insert the code, later I'll see exactly where you modded the code.

That's the best way to learn, thanks.

BTW: I would prefere a loop where I can choose to have the sound once twice etc.

Well ok, but your play sound alert.wav is redundant because Alert(); already plays Alert.wav by default. there are some logic flaws in th alert code though. would you like me to fix them?

Would be nice if you can do so.

I'm not using the alert.wav, I have customized wav files.

I tried to set the code but didn't work, at least in the trading simulator.

Thank you

I am confused then, because your code has the following:

PlaySound("alert.wav");

This will play the alert.wav



void PlaySound( string filename)Function plays a sound file. The file must be located in the terminal_dirsounds directory or in its subdirectory. Parameters:
filename - Path to the sound file.

Do you want to play wav file on the close of the candle or a soon as you get the signal?

As soon as I get the signal please.

The alarm.wav I will change later to my customized one, you can set it to x.wav.

Thank you

This will play the alert only once per candle. I added a variable "datetime PrevTime;". It is used to store opening time of the candle at which last alert was made. If current candle's opening time matches the one saved at this variable, no alert will be triggered.

Let me know if you'll have any questions

Great, thank you very much, I will try it out on sunday and let you know.

It looks like I have a problem with the trading simulator that still give strange sounds or let's say better it repeats the sound every price change.

Have a nice weekend

Alert (Symbol()," ",Period(),"T3 TRIX cross ",UD);

This line will also play sound, but you can disable it on Events tab in MT4 options.

Nice weekend for you too
