Just ring it once?

Hi. I have this code

if(Close[0] > SMA(Input, slowPeriod)[0]) PlaySound(@"C:\Program Files (x86)\NinjaTrader 7\sounds\espacial.wav");

The problem is that it sounds whenever the condition is met.
How could I make it sound only the first time Close [0] > SMA

thank you

Hello julifro,

You could use a variable for that.

private bool canPlaySound = true;

protected override void OnBarUpdate()
{
    if(Close[0] > SMA(Input, slowPeriod)[0] && canPlaySound == true)
    {
        PlaySound(@"C:\Program Files (x86)\NinjaTrader 7\sounds\espacial.wav");
        canPlaySound = false;
    }

}

If you want this to work again the canPlaySound needs to be reset to true again at some point.
