Play Sound once?

[skikg]

Hey all,

I'd like an audio warning when the the bid price rises above a down trending ema. My code works fine but I only want the audio file to play once and then wait for price to go below the ema to reset.

How do I change the play sound file to do what I want?

// Condition set 1 looks for a short down trend in the EMA three bars back
            condition1 = (EMA(14)[3] > EMA(14)[2] && EMA(14)[2] > EMA(14)[1] && EMA(14)[1] > EMA(14)[0]? true : false);
           
            //condition set 2 looks for the bid price to break above the ema for a short signal pull back warning

            condition2= (GetCurrentBid() > EMA(14)[0]? true : false);
            
             /* Condition set 3 takes all conditions and if they all equal true statements it plays a warning sound*/

            if (condition1 && condition2)
            {
               
                PlaySound(audiofile);
            }

Thanks for all the help.

skikg, you will need to create a variable that gets set to true for when your conditions are met and then as soon as the sound file plays, reset the variable to false. Then you can have it be set true again as soon as the conditions are right.

Basically, you just need a variable that gets set/reset at the appropriate times.

How do I reset variable after it triggers first time?

I have set the variable but once it triggers once how do I reset it? I want the script to run and the variable to reset after each 5 min bar. Can I do this in wizard? thanks

ninjablanks, I believe it is possible within the Wizard, but you'll have to get creative with the variables. You can use the user defined variable named Variable0 and then just set it to 1 when your condition is true. Then when Variable0 is set to 1, do whatever action you want it to and reset it back to 0.
