Return more values in a strategy from indicator

[esignal]

is 'possible to get 3 values of an indicator in a strategy?

If I put into value.set (Variable) in the indicator and I see this value when calling the indicator in the strategy ..

But with 3 values I do not know how you can do

Hello esignal,

Thank you for your note.

You would need to set other DataSeries in the script if you want to get more access to more values.

Let me know if I can be of further assistance

[esignal]

can you follow me in this stage of connection between indicator and strategy ... I'm new in programming ninja

My Indicators:

protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
Add(new Plot(Color.FromKnownColor(KnownColor.Green), PlotStyle.Line, "Plot1"));
Add(new Line(Color.FromKnownColor(KnownColor.DarkOliveGree n), 0, "P1"));
Add(new Line(Color.FromKnownColor(KnownColor.Khaki), 0, "P2"));
Overlay = false;

pass1 = new DataSeries(this);
pass2 = new DataSeries(this);
}
///<summary>
/// Called on each bar update event (incoming tick)
///</summary>
protectedoverridevoid OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
Plot0.Set(Open[0]);
Plot1.Set(Close[0]);

pass1.Set(Open[0]);
pass2.Set(Close[0]);

}



OK...i create indicators with 2 dataseries...
And now what do I write in the strategy to retrieve the values pass1 pass2?

Esignal,

You will need to call the indicator name and the property that you wish to grab

Example of this is the MACD -

MACD(int fast, int slow, int smooth).Avg[0];

This will create a new instance of the MACD in the Strategy. You will need to pass values through it for the fast, slow, and smooth. The Avg tells the script to access the data from the Avg plot and [0] will index the current bar's value for the Avg plot.

This will be a similar setup with your custom indicator.

Let me know if I can be of further assistance.

Instread of MACD(int fast, int slow, int smooth).Avg[0]

i put MyIndicator(parameters).pass1[0]

Is correct?

thanks you...now i test it

[esignal]

I did a test with your example:

double contalevel2 = 0;
contalevel2 = MACD (3,3,6). Avg [10];

Print (contalevel2);

OUTPUT:
0
0
0

are all zero

what did I do wrong?

[esignal]

///</summary>
protectedoverridevoid OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.

double contalevel2=0;
if (CurrentBar < 20) return;

contalevel2=MACD(3,3,6)[10];

Print(Time[0] + "$ " + contalevel2);

}


OUTPUT :

0
0
0
0
0
0
0

Esignal,

That is because your Fast and Slow settings are the same.

MACD(3,3,6)[10];

You will need to offsetting values here.

[esignal]

you're right ... what a stupid I am .. I took the only example in case that does not work

[esignal]

I continue in this thread other problems due to the recall indicators..


I use my previous indicator

DELETELEVELS (Name indicators)
-------

double gg=OBV_Ratio;

Value.Set (dd);

-------


I tried to recall from another indicator
---------------------------------
if (CurrentBar <20) return;

double contalevel2;
contalevel2=DELETELEVELS (5) [1];


Print (Time [0] + "$" + contalevel2);
--------------------------------

but I get this error (see below)

[NinjaTrader_CalH]

Esignal,

Can you please attach your custom script that you are trying to call in the new script so that I can test it on my end?

You can attach documents by clicking Go Advanced -> Paperclip in the top tool bar

[esignal]

Ok .. I have attached the file ... (DELETELEVELS is the beginning of a program .. so you will not find in a code that works))

The indicator BobbyTest called DELETELEVELS

[NinjaTrader_CalH]

Esignal,

I tested out your script and you shouldn't have to pass 5 through the ().
Just leave it blank as your indicator does not take any 'Arguments' for the script

[esignal]

Thank you ...

still 2 questions

1) When I run bobbytest to display the data that is passed from deletelevels gives me the following error (the error is in real time) :
Error on calling 'OnBarUpdate' method for indicator 'DELETELEVELS': Object reference not set to an instance of an object"

*******
i noticed that the error is due to this instruction"ChartControl.ChartPanel.Invalidate ()"
inside the indicator DELETELEVELS...

How can I fix this error in maintaining that istruction?

2)if I want to pass a parameters(depthLevel) ... How do I set the indicator DELETELEVELS?

Thanks for the time you lose with me

Why no one answer me?
