Email Price Alert Indicator

[brucelevy]

I need some help adding a simple check so that emails are only sent once when price is touched. I've tried applying some methods but can't seem to get it to work.

SendMail(fromEmail, toEmail, "Price Alert", "Price level was hit at: " + PriceLevel);

Hello brucelevy,

Thanks for your post.

As mentioned in this thread http://ninjatrader.com/support/forum...ad.php?t=85165 You would use a bool to prevent multiple e-mails. You will also need to be able to reset that bool when you are ready for further e-mail.

public class EmailPriceAlert : Indicator
{
#region Variables
// Wizard generated variables
private double priceLevel = 1; // Default setting for PriceLevel
private string toEmail = " "; // Default setting for ToEmail
private string fromEmail = " "; // Default setting for FromEmail
[COLOR="Blue"]private bool doitonce = true;  // for e-mail[/COLOR]
// User defined variables (add any user defined variables below)
#endregion

/// <summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
/// </summary>
protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.HLine, "PriceAlert"));
Overlay = true;
CalculateOnBarClose = false;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{
if(CurrentBar < 1)
return;

PriceAlert.Set(PriceLevel);

if(Close[0] == PriceLevel[COLOR="blue"] && doitonce[/COLOR])
{
SendMail(fromEmail, toEmail, "Price Alert", "Price level was hit at: " + PriceLevel);
[COLOR="blue"]doitonce = false; // set so only send one e-mail[/COLOR]
}

[COLOR="blue"]if (your condition to reset the e-mail)
{
doitonce = true; // re-enable for e-mail
}[/COLOR]

}

Thanks that worked perfectly.

How could this be applied to a trailing stop loss order?

I am trying to send an email every time the stop is moved up behind price.

Hello brucelevy,

Thanks for your post.

You are likely to generate a lot of e-mails depending on the number of ticks on your trailing stop so it may not be wise to do so.

Assuming you are using the setTrailStop() method, one way that this could be done is to test for the name "Trail stop" in the OnOrderUpdate() method .

For example:

protected override void OnOrderUpdate(IOrder order)	
		{
			if (order.Name == "Trail stop")
			{
				
				if (trailprice != order.StopPrice)  // test for new price
				{
					trailprice = order.StopPrice;
					DrawDot ("test"+DateTime.Now, false, 0, trailprice, 
Color.Red);
                                       SendMail(....);
				}
			}

		}

(Note: trailprice is a double that i declared in region variables.

Hi

Just wondering about retrieving data from Tools Misc Email settings the default email sender info.
Is there a way to get the info to save putting it in to each indicator. I thought maybe leaving Blank would call the default. Obviously a recipient email is required just wanting to save the user from headaches.

private string fromEmail = " "; // Default setting for FromEmail

Any help appreciated.
Thanks Raef

Hello raefon72,

Thanks for your post.

While this would not be supported you can try:

Print (NinjaTrader.Cbi.Globals.MailUser.ToString());

[raefon72]

Hi,

It compiled ok but didnt call the default email address. I got a log error "system format exception"

if (zzemail == true){SendMail(NinjaTrader.Cbi.Globals.MailUser.To String(),emailaddress, "Trade Alert ", "Bear Pin "+ Instrument.FullName+" "+ Close[0]);}

Thanks Raef

Hello raefon72,

Thanks for your reply.

I had no issues here using:

if (!Historical && doitonce)
{
SendMail(NinjaTrader.Cbi.Globals.MailUser.ToString (), NinjaTrader.Cbi.Globals.MailUser.ToString(), "trade test", Close[0].ToString());
doitonce = false;
}

I also tried changing the "To:" to a direct e-mail address which also worked.

I notice that you have To String instead of ToString.

[raefon72]

Hi,

Thanks Very much it worked a charm once I removed the space.
This removes the need for double entries on the indicator.
Thanks Raef (;

Hi Guys,

I'm having a bit of trouble retrieving the current charts Time period to add to the email.

+ PeriodType.Minute.ToString()

if (zzemail == true){SendMail(NinjaTrader.Cbi.Globals.MailUser.To String (), zemailaddress, "Trade Alert ", "Bear Pin "+ Instrument.FullName+ " "+ Close[0]+ PeriodType.Minute.ToString());}

The email is sending the word minute but not the Int vale.

Bull Pin $AUDUSD 0.7379Minute

Any help Appreciated.
Thanks Raef

Hello raefon72,

Thanks for your post.

In this case you would want to use the BarsPeriod.Value. Please see the helpguide and note the example: https://ninjatrader.com/support/help...barsperiod.htm

[raefon72]

Thanks.
I tried bars in progress and a few others but BarsPeriods. worked a treat.

I used 2 types.

" Chart Type "+BarsPeriods[0].BasePeriodType+" " +BarsPeriod.Value

Bear Pin $AUDUSD 0.7419 Chart Type Minute 1

thanks again.
