Use indicator in another Indicator....How i declare it?

[turbofib]

i want to use Indicator BuySellPressure in my Pippo Indicator

i don't know how i declare it ::

1)
BuySellPressure bsP;

protected override void OnStateChange()


bsP=BuySellPressure;

protected override void OnBarUpdate()

Print("tempo " + time[0] + "delta " + delta[1]);

2)


Series<BuySellPressure> bsP;

protected override void OnStateChange()

bsp=new Series<BuySellPressure>(this,MasimumBarsLookBack.I nfinite);



What is the method corret? thanks

(i need of 2 properties of BuySellPressure : BuyPressure and SellPressure)

Hello turbofib,

Thank you for writing in.

BuySellPressure() is an indicator method, so you would need to place parenthesis after BuySellPressure.

Example:

bsP = BuySellPressure();

For more information about the BuySellPressure() indicator method, please take a look at this help guide link: http://ninjatrader.com/support/helpG...llpressure.htm

[turbofib]

ok...

But if my indicator have

Calculate = Calculate.OnBarClose;

And i write in my code

protected override void OnBarUpdate()
{
Print BuySellPressure()[1];
}

i see 0 value..because my indicator is
Calculate = Calculate.OnBarClose;

and buySellPressure is
Calculate.OnEachTick;

How i do to print correcty the last pressure in historic bar(for all historic bar)?

See pics

Hello turbofib,

If you wish to print the BuyPressure and SellPressure of the previously closed bar, you would need to utilize this syntax:

Print(BuySellPressure().BuyPressure[1]);
Print(BuySellPressure().SellPressure[1]);

For more information about the BuySellPressure() indicator method, please take a look at this help guide link: http://ninjatrader.com/support/helpG...llpressure.htm

how to declare delta

Hello,

I have following script and I would like to use delta of "plotval" for next calculation to use it in section if..... I am running in the circle and menu help is not helping me. I am not an programer......

double plotval=CCIMA(period,Smooth)[0];

private double delta()
{
return (plotval)[0]-(plotval)[1];
}

if (colorbackground)
{
if (delta >= CCIthreshold)
BackColorAll = Color.FromArgb(opacity,BgColorUp);

else if (delta <= -CCIthreshold)
BackColorAll = Color.FromArgb(opacity,BgColorDown);

else BackColorAll= Color.Empty;

Thank you

Hello Miroslav,

It does not look like you are properly calling the delta() method.

You need to ensure to place parenthesis after delta if you are wishing to call the delta() method.

I would suggest taking a look at this link for more information about utilizing methods in C#: http://www.tutorialspoint.com/csharp/csharp_methods.htm

Additionally, you are attempting to access an index on a double variable. A double variable is only going to hold one value.

I would suggest creating a variable of type CCIMA.

Example:

CCIMA plotval;

protected override void Initialize()
{
     plotval = CCIMA(period, Smooth);
}

private double delta()
{
     return plotval[0] - plotval[1];
}

Before accessing the barsAgo value of 1, ensure that you have enough bars in the data series you are accessing. Please take a look at this link for additional information: http://ninjatrader.com/support/forum...ead.php?t=3170

If you are still running into issues, please describe the issue you are running into.

Please, let us know if we may be of further assistance.

Hello Zachary,

thank you for your answer. I tried to modify my script. I have looked to linked you provided but it does not helped me too much. I tried to modify my script. Still I have some issue to complile it.

Hello miroslav,

I do want to note the reason why you are receiving an "already contains a definition for delta" error is because you have created an int variable called delta. You will need to either remove or rename this variable as it is conflicting with the delta() method.

Additionally, you have declared plotval as int. This will need to be of type CCIMA.

I see that you are also trying to set your DataSeries (CCImiddle, CCIoverbought, CCIoversold, CCIbarHi, and CCIbarLow) to plotval. plotval is a DataSeries; you cannot pass a DataSeries in a Set() method.

If you wish to pass the current value of plotval, you will need to specify the index of 0:

plotval[0]

Please, let us know if we may be of further assistance.

Hello Zachary,

is it possible to do it in this way or it will make some overloading of ninjatrader.

Thank you

Hello miroslav,

I am not entirely clear of your question.

Please note that we do not provide debugging services; I have only resolved the compile errors for you.

If you are running into unexpected behavior ,I would first suggest to consult the information found at this link for information about debugging your code: http://ninjatrader.com/support/forum...ead.php?t=3418

If you are running into any specific issues and are unsure of why the behavior is occurring, please provide the results you see, the results you expect, and what debugging steps you have already done to try to resolve the unexpected results.

Hello Zachary,

no I am not asking for debugging services but I run compile correctly and there is no output of indicator also log is empty so I do not know what is issue now.

Hello miroslav,

What debugging steps have you already done?

What values are you seeing when debugging? What values are you expecting? Are any errors appearing in the Log tab?

Hello,

there is nothing in the log tab. And I see in indicator following things, see picture.

Hello miroslav,

I have noticed that you have placed...

double delta =(Math.Abs((plotval[0]))-Math.Abs((plotval[1])));

...in OnStartUp(). This will result in a run-time error as the data you are trying to retrieve is not available yet.

You will want to do this calculate in OnBarUpdate(), before all of your other logic. Also, ensure that you are checking that you have enough bars before attempting to access plotval[1]: http://ninjatrader.com/support/forum...ead.php?t=3170

Additionally, you have set plotval as a DataSeries rather than of type CCIMA. You will want to make plotval of type CCIMA if you wish to set the indicator to this variable.

Lastly, ensure to initialize plotval within OnStartUp() rather than Initialize(). I apologize for stating to initialize plotval from Initialize() in my previous post; this will cause the indicator to always return 0.

protected override void OnStartUp()
{
     plotval = (CCIMA(period, smoothperiod));
}

Please, let us know if we may be of further assistance.

Hello Zachary,

thank you for your reply

what do you mean by "You will want to make plotval of type CCIMA if you wish to set the indicator to this variable."

I made suggested modifications but I am running in the circle with error message: "Cannot implicitly convert NinjaTrader. Indicator CCIMA to NinjaTrade.DataSeries and it is addressing the following code

protected override void OnStartUp()
{
plotval = CCIMA(period, smoothperiod);
}
