Is correct to use this indicator in this way?

[esignal]

hi...look my code .

my indicator :

namespace NinjaTrader.NinjaScript.Indicators
{ 
public class Xx
{ 
private bool signal= (espression);
}

public class Class2 : Indicator
{
public List<Xx> MT;
private Xx useClass; 
}
protected override void OnBarUpdate()
{

Xx tmp1 = new Xx();
MT.Add(tmp1); 
MT[MT.count-1].signal= //Logic espression 

}

In my indicator i build a logic to using a list of class

In my strategy is correct to do this : (i want to enter signal by my Class2 Indicator)

  
 public class  StStrategy: Strategy
 {
 .....
 protected override void OnStateChange()
 if (State == State.SetDefaults)
 {
         .............
 {
  else if (State == State.Configure)
 {
                mt = Class2();
        }
 
protected override void OnBarUpdate()
 {
     if (mt.MT[mt.MT.Count-1].Xx)
                EnterLong();
                ....
                ....
        
  
  }

The question is: is good to use

  
 if (mt.MT[mt.MT.Count-1].Xx)

to recall indicator or is better use DataSeries in indicator (in dataseries i copy the value of list in this )...e use Dataseries in strategy...

i don't know if it's the same or not..help me..

thank

Hello,

I'm not entirely clear on your final question, but your code should work as expected if you set it up the way you have laid out. Keep in mind that Class2 would be using the same data series as the strategy in this case, if that makes any difference (I'm not sure how DataSeries comes into play in your question).

ok...but see that example :

i apply indicator and strategy to chart

in My indicator i write (in OnBarUpdate) :

protected override void OnBarUpdate()
{
Print(MT.Count);
}

and i see :

Is correct !!

but if i write in my esignal

protected override void OnBarUpdate()
{
Print(mt.MT.Count);

i see :

it's not corret.

it seems that does not make the update of indicator

Hello esignal,

Thank you for your response.

So you have scripts we could test this in?

[esignal]

okk..
Now attached an example..
The problem is the same..

[esignal]

hi, are you understand this problem? or not?

[NinjaTrader_PatrickH]

esignal,

Thank you for your patience.

In your strategy you would change the following...

			else if (State == State.Configure)
			{
                gt = new forumIndicator();
			}

to...

			else if (State == State.Configure)
			{
                gt = forumIndicator();
			}

'new' instantiates the indicator without any loaded bars.

Hello eSignal,

I did forget to mention the use of Update():

			gt.Update();
            Print(gt.MT.Count);

Excuse me

Update() is a command of nt7?

Thank you, but this is also available in NT 8: http://ninjatrader.com/support/helpG...-us/update.htm

Check out the ZigZag indicator in NinjaTrader 8 for example.
