add an audible alert to the indicator (PIDOsc1)

[Miguelcuello16]

Good day, I am alert trying to add a sound alert to the indicator (PIDOsc1) The Pivot Detector Oscillator, Simplified, ported to nt8 by NinjaTrader_Paul
I would like the alert to sound just when the indicator draws the bullish or bearish arrow,
I would be very grateful if you can help me please

Hello Miguelcuello16,

Thank you for your post.

You would need to modify the code here and you could use PlaySound() to play the sound of your choosing:

if (CrossAbove(Oscillator, 0, 1))
{
// Draws an up arrow as a buy signal five ticks below the low of the current bar
Draw.ArrowUp(this, "Oversold" + CurrentBar, false, 0, Low[0] - 5 * TickSize, Brushes.CornflowerBlue);
// Plays the default Alert1 sound that comes packaged with NinjaTrader
PlaySound(NinjaTrader.Core.Globals.InstallDir + @" \sounds\Alert1.wav");
}

// This CrossBelow checks for an overbought condition.
else if (CrossBelow(Oscillator, 100, 1))
{
// Draws a down arrow as a sell signal five ticks above the high of the current bar
Draw.ArrowDown(this, "Overbought" + CurrentBar, false, 0, High[0] + 5 * TickSize, Brushes.Orange);
// Plays the default Alert1 sound that comes packaged with NinjaTrader
PlaySound(NinjaTrader.Core.Globals.InstallDir + @" \sounds\Alert1.wav");
}

Thanks for your help, and prompt response.

I managed to compile the code but it still does not emit the sound alert when the arrows appear, I enclose the code, maybe it has something wrong

Hello Miguelcuello16,

Thank you for your reply.

Looks like there's a minor typo in the alert line. Try the following:

PlaySound(NinjaTrader.Core.Globals.InstallDir + @"sounds\Alert1.wav");

Please let us know if we may be of further assistance to you.
