play sound 2x's

[velocity]

I have the following signal that plays a sound when true

if(mySignal[0] == 1.0)
{
DrawDot("MyDotbuy"+CurrentBar, true, 0, Low[0] - (2 * TickSize), Color.Blue);
PlaySound("Alert1.wav");
}

How do I get the sound to play only 2x's when it is true. Currently it beeps every time when the bar is updating.

Can anyone show me an example?

Thanks

Hello,

Try something like this:


if(mySignal[0] == 1.0 && cnt < 2)
{
DrawDot("MyDotbuy"+CurrentBar, true, 0, Low[0] - (2 * TickSize), Color.Blue);
PlaySound("Alert1.wav");
cnt++;
}

//you will need to put int cnt = 0; somewhere, where you want to
//allow the signal to reset and allow it to go off again.

thanks, I will give it a try

Hi Ben,

I tried your script and could not get it to work, the sound continued to play repeatedly. I tried the following:

protectedoverridevoid OnBarUpdate()
if (condition)

{

for (int x = 0; x < 2; x++)
{
PlaySound("Alert1.wav");
}

}

any thoughts?

velocity,

Your variant will not work. You should try what Ben suggested with a counter variable instead of a loop. Your loop is reset every time your trade condition is true. Your counter should be a part of the condition at the very beginning.

[velocity]

I have tried many many different variations to try and make this work and the counter just does not add when I look in the output window. the number is always #1.


protectedoverridevoid OnBarUpdate()

int count = 0;

if(mySignal[0] == 1.0)
{
DrawDot("MyDotbuy"+CurrentBar, true, 0, Low[0] - (2 * TickSize), Color.Blue);
count++;

if(count < 2) {PlaySound("Alert1.wav");}

Print(Time[0].ToLongTimeString() + " " + count.ToString());

}


The condition may be true 500+ times when the bar is forming. The output window just prints rapid #1's as the bar is updating instead of counting 1,2,3,4, etc. As a result the beeps are in rapid fire play mode. I only want one beep per bar.

Where am I going wrong?

int i = 2
while (i > 0)
{
PlaySound("Alert1.wav");
i--;
}

I am a little lost on your post.

Are you saying:


protectedoverridevoid OnBarUpdate()

if(mySignal[0] == 1.0)
{
DrawDot("MyDotbuy"+CurrentBar, true, 0, Low[0] - (2 * TickSize), Color.Blue);

int i = 2;
while (i > 0);
{
PlaySound("Alert1.wav");
i--;
}


Print(Time[0].ToLongTimeString() + " " + i.ToString());

}

[bukkan]

ya, and since you dont want it on historical do add

if (Historical)
{
// dont play sound

}

again you can simply make a copy of the the wav file and call it twice

if (condition)
{
PlaySound("Alert1.wav");
PlaySound("Copy of Alert1.wav");
}

Sorry, I can't follow what you are doing there. I have way too many conditions to add that kind of coding to my indicator.

Thanks for taking a look.

Anyone else have an Idea?

[NinjaTrader_Bertrand]

velocity, which exact code are you know using? Wouldn't this work for you below as suggested in this thread?

 
protected override void OnBarUpdate()
{
if (Close[0] > Open[0])

{ 
alertCalls = 2;
while (alertCalls > 0)
{
PlaySound("Alert2.wav");
alertCalls--;
}
}
Plot0.Set(Close[0]);
}

[velocity]

I don't get it. Your code continually beeps when close is above open. I want to do just the opposite. I only want the beep to sound off 2x as long as price is above open on the Current Bar. If it falls back below the open it resets and then if price rises above open again on "the Current Bar", it will beep 2x's and then stop.

The way you have it written, as long as price is above open, it beeps.

Any thoughts on how to accomplish this would sure be appreciated.

thanks

this is what I have as an example:

#region Variables
// Wizard generated variables
privateint myInput0 = 1; // Default setting for MyInput0
int alertCalls = 0;

#endregion

protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
CalculateOnBarClose = false;
Overlay = false;
}

protectedoverridevoid OnBarUpdate()
{

if (Close[0] > Open[0])
{
alertCalls = 2;
while (alertCalls > 0)
{
PlaySound("Alert2.wav");
alertCalls--;
}
}
Print(Time[0].ToLongTimeString() + " " + alertCalls.ToString());
Plot0.Set(Close[0]);
}

[eDanny]

Use a bool?

#region Variables
// Wizard generated variables
privateint myInput0 = 1; // Default setting for MyInput0
int alertCalls = 0;
bool CloseAboveOpen = false;

#endregion

protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
CalculateOnBarClose = false;
Overlay = false;
}

protectedoverridevoid OnBarUpdate()
{

if (Close[0] > Open[0])
{
if(!CloseAboveOpen)
{
alertCalls = 2;
while (alertCalls > 0)
{
PlaySound("Alert2.wav");
alertCalls--;
}
CloseAboveOpen = true;
}
}
Print(Time[0].ToLongTimeString() + " " + alertCalls.ToString());
Plot0.Set(Close[0]);
}
if(Close[0] < Open[0])
CloseAboveOpen = false;


Not tested. Dan

In addition to eDanny's idea/code, you could also simply combine the single beep into a double beep with some sound editing program and then you wouldn't have to worry about triggering it twice. That would greatly simplify the rest of the process.

[mrlogik]

Austin has the best idea.

All of these options with loops and such will probably have the sound file play twice, but the sounds may overlap depending on the length of time they require to play. Best bet is to just modify the sound file itself to loop.
