audio alert upon completion of a bar

[stephenszpak]

I've tried to find/understand how to get an
audio file to play when a bar is complete, or
better yet, a few seconds before. If a chart
is using 2 minute bars I would like an alert
when a bar is about done (110 seconds). I've tried to get
market analyzer to do it but have given up
for now.

Is there a way? I've tried Columns, then Last Close,
but I'm not sure what I'm doing.

I guess PercentComplete might work?
I'll try that unless I get a comment.

Ok, I'm heading out now. I did get an alert to sound
upon the completion of a bar.

{
if(Bars.PercentComplete>0)


{

PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\Alert1.wav");
}

I've tried to get the alert to sound a few seconds earlier but
all the values that I replace '0' with don't help.

Any suggestions?

Thanks,

Make sure you have Calculate on bar close set to false

Thanks, I don't think I would have figured this
out. It helps, but the alert keeps playing until
the end of the bar. I tried BREAK and using
a < and >, FOR, and one or two other things.
but it won't generate because of some
error in how I'm doing it.
Spent about 45 minutes.

{
if (Bars.PercentComplete>.91666)
{

PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\110 seconds.wav");





}

There is also another problem. I have converted a text file to audio
to play "110 seconds, 110 seconds". But it plays" 100 100 100 110
seconds 110 seconds".

If I substitute the Alert1 sound that comes with NT, it plays 4 times
within my script. But it plays just once in WinAmp.

I think there is a connection with the two situations here.

It seems the sound that is played is automatically repeated a number
of times when using PlaySound(@''C:\Program Files\NinjaTrader 6.5\sounds
which is not useful in what I'm going for here.

if (Bars.PercentComplete>.91666)

This will be "true" more than one time.

Set a flag, like:

bool playedaudio = false;

then once you play it (after PlaySound) set to true:
playedaudio = true;

be sure to reset it on the next bar:

if (FirstTickOfBar)
playedaudio = false;

I tried what you said, (probably incorrectly) it doesn't work.

I altered the WAV file to play "110 seconds, 110 seconds"
to which I added thirty seconds of silence. It plays correctly
in WinAmp.

So in NT it's NOT like it's repeating until the end of the bar.
It's almost stuttering. It's saying 100, like five or six times,
then 110 seconds, 110 seconds. The longer the duration of the bar
the greater the number of times it says '100'. So it is repeating, but
not repeating the entire audio file. Even if it played just once I think
it would not play correctly.

Are you reproducing this using market replay? What speed, if so?

I use audio alerts as well, and in a market replay session they will get cut off and trampled on due to the replay speed.

Having 30 seconds of white space at the end is not going to accomplish anything in my opinion, NT will just cut off the audio file in the middle of playing if it wants to play another one. It doesn't wait for the file to finish playing.

Just using simulated data at normal speed.
120 second bars, or less so I don't have to wait too long.

Throw in a couple of Print statements so we can see what is happening. Remember to open the Output Window.

Print(Time[0] + ": blah blah" + ", % complete = " + Bars.PercentComplete.ToString() + ", Close[0] = " + Close[0]);

change the blah blah to something useful like "before audio" and "after audio" etc.

Then run it again and see what is happening, notice the time stamps.

Also,

Going back to the boolean for playedaudio.

On your PlaySound() line, it needs to be:

if (!playedaudio)
PlaySound()

Mike

[ctrlbrk]

#variables
bool playedaudio = false;

#onbarupdate
if (FirstTickOfBar)
{

Print(Time[0] + ": I am resetting playedaudio to false, % complete = " + Bars.PercentComplete.ToString() + ", Close[0] = " + Close[0]);

playedaudio = false;

}

if (Bars.PercentComplete>.91666 && !playedaudio)
{

Print(Time[0] + ": I'm about to play some sound, % complete = " + Bars.PercentComplete.ToString() + ", Close[0] = " + Close[0]);

PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\110 seconds.wav");

playedaudio = true;

}

Thanks. I'll try for an hour or so.

I got this and I lost it, and I got it, so I'm posting it now.
The program below plays "110 seconds, 110 seconds"
The problem should be quite simple now. It ONLY does this
for the first bar. The stuttering is gone, which was very important.

--------------------------------------------------------------

The...

#onbarupdate
if (FirstTickOfBar)


...which was suggested, was not done correctly on my part.
There was an error I couldn't get rid of so it's not part of the programming below.
-------------------------------------------------------------------------

If this line is NOT in the program below, there is stuttering:

playedaudio = true;

-------------------------------------------------------------------------------

#region Variables

bool playedaudio = false;


// Wizard generated variables
private int myInput0 = 1; // Default setting for MyInput0
// User defined variables (add any user defined variables below)
#endregion

protected override void OnBarUpdate()


{


if (Bars.PercentComplete>.91666 && !playedaudio)
{



PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\110 seconds 110 seconds.wav.");


playedaudio = true;

}
