how to control one indicator with another indicator

[paruchuriphani]

Hi,

i am using two indicator in my assembly file. i want to control my first indicator with second one.

EX: if my MACD indicator gave me a buy call in that time i want to check my Trend showing indicator. if my Trend showing indicator is in down trend. i don't want draw any green arrow in my chart. vice versa for sell calls also.

Thank You.

Hello paruchuriphani,

You can expose an object like a Bool using a BoolSeries that you can have the other indicator check for to make sure that you are trending. The following thread has a reference sample that goes over how to expose indicator values that are not Plots that you may use to accomplish this.

hi,

thanks for your reply.

please give your ticket number . i will send my cs file. please tell me how to use BoolSeries in my case.

thank you,

Hello paruchuriphani,

You may send an email to Support [at] ninjatrader [dot] com with a reference link to this thread and put "ATTN: JC" in the subject and I can take a look at it.

Hi JC,

Thank you for your reply,

I changed my MACD indicator code like this.please tell me this is correct or not?

This my old code:

#region Variables

private bool up = true;
private bool down = true;

#endregion

protected override void Initialize()

bbMacd = new DataSeries(this);
dotSeries = new DataSeries(this);

This is my new changed code:

#region Variables

private BoolSeries up = true;
private BoolSeries down = true;

#endregion

protected override void Initialize()

bbMacd = new BoolSeries(this);
dotSeries = new BoolSeries(this);

Next

i want to stop this BUY call code. when Trend indicator in RED

this is my MACD OnBarUpdate() code for buy call

if(CrossAbove(dotSeries, BB_UpperBand,1)&&up)
{
{
Say(" There is a Buy Call in" +Instrument.FullName+"" );
over=true; // only say it once per bar
}
{
DrawDiamond("MyDot"+ CurrentBar, true, 0, dotSeries[0] , Color.Blue);
}
up=false;
down=true;
}

please tell me how to stop this code when my Trend Indicator(TSST) in RED.

Thankyou,

This is my new changed code:

#region Variables

private BoolSeries up = true;
private BoolSeries down = true;

#endregion

protected override void Initialize()

bbMacd = new BoolSeries(this);
dotSeries = new BoolSeries(this);

if(CrossAbove(dotSeries, BB_UpperBand,1)&&up)
{
{
Say(" There is a Buy Call in" +Instrument.FullName+"" );
over=true; // only say it once per bar
}
{
DrawDiamond("MyDot"+ CurrentBar, true, 0, dotSeries[0] , Color.Blue);
}
up=false;
down=true;
}

How you set and call a BoolSeries is different than a bool so you would not be able to set it equal to true or false since, it will be like a Data Series in that it will have an series of values much like Bar data. Please read the following Help Guide for more information about the BoolSeries.

http://www.ninjatrader.com/support/helpGuides/nt7/index.html?boolseries_class.htm

Here is an example of how it may look:

#region Variables

private BoolSeries up;
private BoolSeries down;

#endregion

protected override void Initialize()

up= new BoolSeries(this);
down= new BoolSeries(this);

protected override void OnBarUpdate()

if(CrossAbove(dotSeries, BB_UpperBand,1)&&up[0])
{
{
Say(" There is a Buy Call in" +Instrument.FullName+"" );
over=true; // only say it once per bar
}
{
DrawDiamond("MyDot"+ CurrentBar, true, 0, dotSeries[0] , Color.Blue);
}
up.Set(false);
down.Set(true);
}

Hi JC,

thank you so much for your reply,

I changed my code like this after your reference..my code compile fine but OnbarUpdate() functions DrawDiamond & SpeechSynthesizer not working.

#region Variables
private BoolSeries up;
private BoolSeries down;
#endregion

protected override void Initialize()
up=new BoolSeries(this);
down=new BoolSeries(this);

protected override void OnStartUp()

if(CrossAbove(dotSeries, BB_UpperBand,1)&&up[0])
{
{
Say(" There is a Buy Call in" +Instrument.FullName+"" );
over=true; // only say it once per bar
}
{
DrawDiamond("MyDot"+ CurrentBar, true, 0, dotSeries[0] , Color.Blue);
}
up.Set(false);
down.Set(true);
}

if(CrossBelow(dotSeries, BB_LowerBand,1)&&down[0])
{
{
Say(" There is a Sell Call in " +Instrument.FullName+ "");
over=true; // only say it once per bar
}
{
DrawDiamond("MyDot"+ CurrentBar, true, 0,dotSeries[0] , Color.White);
}
up.Set(true);
down.Set(false);
}
}

#region Properties
/// <summary>
/// </summary>
[Browsable(false)]
[XmlIgnore()]
public BoolSeries Up
{
get { return up; } // Allows our public Up BoolSeries to access and expose our interal up BoolSeries
}

[Browsable(false)]
[XmlIgnore()]
public BoolSeries Down
{
get { return down; } // Allows our public Down BoolSeries to access and expose our interal down BoolSeries
}

please tell me Where do I get it wrong.I done exactly what you told in your last post.please help me.

Thank You,

From your last post, I do not see the OnBarUpdate() method referenced in your code -

Are you sure you have added logic here? I only see this added to OnStartUp() which only works on the first bar on the chart.
