Hello paruchuriphani,

Thank you for your post.

The following code snippet shows how to create these alerts, this would be added to the OnBarUpdate() method:

                       if(CrossAbove(dotSeries, BB_UpperBand, 1))
			{
				Alert("Up", NinjaTrader.Cbi.Priority.High, "MACD crossed above Upper Band", "Alert1.wav", 10, Color.Black, Color.Yellow);
			}
			if(CrossBelow(dotSeries, BB_LowerBand, 1))
			{
				Alert("Down", NinjaTrader.Cbi.Priority.High, "MACD crossed below Lower Band", "Alert1.wav", 10, Color.Black, Color.Yellow);
			}

For information on Alert() please visit the following link: http://www.ninjatrader.com/support/h.../nt7/alert.htm

For information on CrossAbove() please visit the following link: http://www.ninjatrader.com/support/h...crossabove.htm

For information on CrossBelow() please visit the following link: http://www.ninjatrader.com/support/h...crossbelow.htm

Please let me know if you have any questions.

Hello paruchuriphani,

Thank you for your response.

Please go to the NinjaTrader Control Center > Tools > Edit NinjaScript > Indicator > double click on the MACDBBLines > then in the OnBarUpdate() section of the code add the bold lines below:

		protected override void OnBarUpdate()
		{
		
			bbMacd.Set(MACD(Input, fast, slow, smooth)[0]);
				
			double Avg = EMA(bbMacd,length)[0];
			double SDev = StdDev(bbMacd,length)[0];	
			double upperBand=Avg+(stDv*SDev);
			double lowerBand=Avg-(stDv*SDev);
			
			BB_UpperBand.Set(upperBand);
   			BB_LowerBand.Set(lowerBand);
			dotSeries.Set(bbMacd[0]);
			currentBar=CurrentBar;
			
			[B][I]if(CrossAbove(dotSeries, BB_UpperBand, 1))
			{
				Alert("Up", NinjaTrader.Cbi.Priority.High, "MACD crossed above Upper Band", "Alert1.wav", 10, Color.Black, Color.Yellow);
			}
			if(CrossBelow(dotSeries, BB_LowerBand, 1))
			{
				Alert("Down", NinjaTrader.Cbi.Priority.High, "MACD crossed below Lower Band", "Alert1.wav", 10, Color.Black, Color.Yellow);[/I][/B]
			}
		}

Once complete press F5 to compile.

Please let me know if I may be of further assistance.

Hello paruchuriphani,

Thank you for your response.

You will need to add the DrawArrowDown() or DrawArrowUp() methods to your code after the desired condition has been met.

For information on DrawArrowDown() please visit the following link: http://www.ninjatrader.com/support/h...warrowdown.htm

For information on DrawArrowUp() please visit the following link: http://www.ninjatrader.com/support/h...rawarrowup.htm

Please let me know if I may be of further assistance.

HI,

Thank you so much for your reply,

I try this code for Draw Up & Down Arrows

protected override void OnBarUpdate()
{

bbMacd.Set(MACD(Input, fast, slow, smooth)[0]);

double Avg = EMA(bbMacd,length)[0];
double SDev = StdDev(bbMacd,length)[0];
double upperBand=Avg+(stDv*SDev);
double lowerBand=Avg-(stDv*SDev);

BB_UpperBand.Set(upperBand);
BB_LowerBand.Set(lowerBand);
dotSeries.Set(bbMacd[0]);
currentBar=CurrentBar;

if(CrossAbove(dotSeries, BB_UpperBand, 1))
{
PlaySound("alert4.wav");
DrawArrowUp("up arrow" + CurrentBar, false, 0, BB_UpperBand[0] - 2 * TickSize, Color.Green);

}

if(CrossBelow(dotSeries, BB_LowerBand, 1))
{
PlaySound("alert4.wav");
DrawArrowDown("down arrow" + CurrentBar, false, 0, BB_LowerBand[0] + 2 * TickSize, Color.Red);

}
}

But result is like this... please find the attachment

Hello paruchuriphani,

Thank you for your response.

You would create two private bools in the Variables section:

#region Variables
private bool up = true;
private bool down = true;

Then you would use these in the condition, if up is true and the CrossAbove() then draw the arrow and play the sound and vice versa for the CrossBelow(). However, the bools must be set as false once the condition is met. For example:

if(CrossAbove(dotSeries, BB_UpperBand, 1) [B]&& up[/B])
{
PlaySound("alert4.wav");
DrawArrowUp("up arrow" + CurrentBar, false, 0, BB_UpperBand[0] - 2 * TickSize, Color.Green);
[B]up = false;
down = true;[/B]
}

if(CrossBelow(dotSeries, BB_LowerBand, 1) [B]&& down[/B])
{
PlaySound("alert4.wav");
DrawArrowDown("down arrow" + CurrentBar, false, 0, BB_LowerBand[0] + 2 * TickSize, Color.Red);
[B]up = true;
down = false;[/B]
}

Please let me know if you have any questions.

Hello,

While I can't verify the correctness of the if statement the SendMail() does look correct as you have it in the format

SendMail(string from, string to, string subject, string text)

one thing i noticed is that your "to" email address might have a typo

not sure if you wanted to have [email protected]

[paruchuriphani]

Thanks for your reply

i will change that mail ID yahoo to gmail...after i change that email ID. is that work's or not?

please tell me about "Instrument.MasterInstrument.Name"

[NinjaTrader_Lance]

Hello,

If that is a valid email address then it will work. I was just pointing this out as I did not know if this was a typo or the correct input for your email address.

please tell me about "Instrument.MasterInstrument.Name"

This will give you the name of the instrument being used:

Hello,

There isn't a supported way to have your indicator plot to more than one panel. You would need to use a separate script to perform this check.

You could create a strategy/indicator that looks at the MACDBB values and then draws the arrows on the primary panel

Please let me know if I can be of further assistance.

[paruchuriphani]

Hello,

please give me more information on how to create a "strategy/indicator" please give me your guidance.
