How to make this work? SOUND ALERT

[fredyyy]

Hey guys, im sorry if this is repost, but i've looked around and i still cant get trough this:

Im trying to create an indicator which gives out a sound alert at the first bar tick after a MA crossover.

When i write it, i have to "compile" it to finish it right?

Im using two variable moving averages (a slow one with MAperiod and typeint parameters 150, 4 and a fast one with 30, 4)

Ive coded a lot but when im compiling the indicator it always gives me an error.

Here's what i got so far:



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

private bool soundOn = true; // on/off switch for audio alerts
private string alert1Sound = "long.wav"; //audio alert for Condition1
private string alert2Sound ="short.wav"; //audio alert for Condition2
private bool Condition1 = CrossAbove(MAV(30,30,4), MAV(150,150,4));//will be set to the conditions for alert1
private bool Condition2 = CrossBelow(MAV(30,30,4), MAV(150,150,4)); //will be set to the conditions for alert2

(Are the bool statements above well written? are they in the right space? I didnt know what to put in the MAV parameters since i only know 2 and it requires 3... the MAV im using is the NT standart)

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
if (Condition1 && soundOn && FirstTickOfBar) PlaySound(alert1Sound);
if (Condition2 && soundOn && FirstTickOfBar) PlaySound(alert2Sound);
}

#region Properties
[Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
[XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
public DataSeries Plot0
{
get { return Values[0]; }
}

[Description("")]
[Category("Parameters")]
public int MyInput0
{
get { return myInput0; }
set { myInput0 = Math.Max(1, value); }
}
#endregion
}
[Description("what will help the user decide how to choose their entry")]
[Category("Parameters")]
public string LongSound (it gives me an error right here, saying something's wrong with this line)
{
get { return alert1Sound; } // this name matches that in the Variables section
set { alert1Sound = value; }
}
[Description("what will help the user decide how to choose their entry ")]
[Category("Parameters")]
class string ShortSound (and this line)
{
get { return alert2Sound; } // this name matches that in the Variables section
set { alert2Sound = value; }
}
}


You can cut out anything you find to be wrong or useless..

Thanks a lot to anyone who can give me a hand

Hey Fredyyy,

(....)
private bool soundOn = true; // on/off switch for audio alerts
private string alert1Sound = "long.wav"; //audio alert for Condition1
private string alert2Sound ="short.wav"; //audio alert for Condition2

This could work, however, you shouldn't forget to "tell" Ninjatrader in which directory these files are located (through the use of Alert() is this done automatically, see below).

private bool Condition1 = CrossAbove(MAV(30,30,4), MAV(150,150,4));//will be set to the conditions for alert1
private bool Condition2 = CrossBelow(MAV(30,30,4), MAV(150,150,4)); //will be set to the conditions for alert2

(Are the bool statements above well written? are they in the right space? I didnt know what to put in the MAV parameters since i only know 2 and it requires 3... the MAV im using is the NT standart)

What do you mean with MAV? A simple moving average I guess? Then you have to use the SMA. Also, you're missing the lookback period of the CrossAbove statement.

I'm wondering what kind of 'moving averages' you intend to use, because in your post you state you have two moving averages (a long period and a short period). However, in your code I see 3 different periods? (150 bars, 4 bars, and 30 bars).

Perhaps you could try this:

// gives "true" if the SMA 30 closes above the SMA 150 on the last bar
private bool condition1 = CrossAbove(SMA(Close, 30), SMA(Close, 150), 1);  
 
// gives "true" if the SMA 30 closes below the SMA 150 on the last bar
private bool condition2 = CrossBelow(SMA(Close, 30), SMA(Close, 150), 1);

And for your sound alert:

private string alert1Sound = "long.wav"; 
// the name of the file in the Ninjatrader folder (probably C:\Program Files\NinjaTrader Installation Folder\sounds)
 
private string alert2Sound ="short.wav"; 
//the name of the file in the Ninjatrader folder (probably C:\Program Files\NinjaTrader Installation Folder\sounds)
 
(...)
if(condition1 == true)
{
Alert("Buy signal", NinjaTrader.Cbi.Priority.High, "A crossabove just took place", alert1Sound, 0, Color.Black, Color.Yellow);
}
if(condition2 == true)
{
Alert("Sell signal", NinjaTrader.Cbi.Priority.High, "A crossbelow just took place", alert2Sound, 0, Color.Black, Color.Yellow);
}

See also this help section on Alert().


Good luck and I hope my reaction is of some use to you.

J o s

Thank you!

You are right about the Simple moving averages, my bad!

This is what i corrected after your reply:

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

private bool soundOn = true; // on/off switch for audio alerts
private string alert1Sound = "long.wav"; //audio alert for Condition1
private string alert2Sound ="short.wav"; //audio alert for Condition2
private bool condition1 = CrossAbove(SMA(Close, 30), SMA(Close, 150), 1);//will be set to the conditions for alert1
private bool condition2 = CrossBelow(SMA(Close, 30), SMA(Close, 150), 1); //will be set to the conditions for alert2

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
private string alert1Sound = "long.wav";
// the name of the file in the Ninjatrader folder (probably C:\Program Files\NinjaTrader Installation Folder\sounds) (it is exactly in that folder, do i need to change anything?)

private string alert2Sound ="short.wav";
//the name of the file in the Ninjatrader folder (probably C:\Program Files\NinjaTrader Installation Folder\sounds)

(...) ( <--- Should i leave this? )
if(condition1 == true)
{
Alert("Buy signal", NinjaTrader.Cbi.Priority.High, "A crossabove just took place", alert1Sound, 0, Color.Black, Color.Yellow);
}
if(condition2 == true)
{
Alert("Sell signal", NinjaTrader.Cbi.Priority.High, "A crossbelow just took place", alert2Sound, 0, Color.Black, Color.Yellow);
}
}

}

Have i made the corrections properly? Did i pasted in the right space?


also, Is there any chance to match this to only emit a sound alert when the crossover is followed (in the next 3 or 5 bars) by a cross above/below zero of the ElliotOscilator (fast 71, slow 93, close) ?

Ive made this indicator especially slow, so that i only care about the MA crossovers when the Elliot crosses zero.

What do you think?

Sorry for my n00bieness at programming btw, im really clueless....

[NinjaTrader_Bertrand]

luxurious_04, on what chart and timeframe are you running this script on? Are you sure there's a 2:30 timestamp triggering your condition to raise the Alert?

[luxurious_04]

10 minutes chart.

[NinjaTrader_Bertrand]

Ok, have you checked your charts that you indeed get this timestamp in the session range displayed? Do you also have the Alert window open to monitor this alert being triggered? Please also note those will work in realtime or Market Replay only.

[laredo78676]

no audio

what do I check,plugged in speakers and nt doesnt announce buys sells etc.
thanks

[NinjaTrader_Bertrand]

Are regular sounds from PC / Windows install working as expected?

Are NinjaTrader's sounds enabled (checked) under Tools > Options > General?

Are you running the latest NT release version 6.5.1000.16?

Thanks

[laredo78676]

nt &quot;16&quot;

after I download "16" nt,how do i sttach it to my existing platform?

[NinjaTrader_Austin]

laredo, I'm not exactly sure what you mean. NinjaTrader 6.5.1000.16 is just the most current release of NinjaTrader 6.5. You install it, which would then make it your current platform, and then you can import the indicator again and see if that solves the issue.
