Making an Alert on conditional indicator

[ericadam]

protected override void OnBarUpdate()
        {
            // Use this method for calculating your indicator values. Assign a value to each
            // plot below by replacing 'Close[0]' with your own formula.
			
			if (MACD(12,26,9).Diff[0] > 0 && MACD(12,26,9)[0] > 0)
      			BarColor = Color.Green;
				
			else if (MACD(12,26,9).Diff[0] < 0 && MACD(12,26,9)[0] < 0)
      			BarColor = Color.Red;
			
        }

How would you program this to play an audible alert on a green bar being made and a seperate one for the red bar color. THanks.

Use PlaySound().

if (....)
{
     BarColor = Color.Green;
     PlaySound(@"C:\mySound.wav");
}
