Indicator Output as another inidcator input

[chisound]

Hi:

I am new to Ninjatrader indicator development but am familiar with C#. With Ninjatrader 7 is it possible to use the output of one custom indicator as the input of another custom indicator?

This forum is great! Many thanks for any help you can give.

Hi chisound,

Yes, it certainly is.

For example, if you have one indicator with a plot named Plot1, you can call it from another indicator...

double Variable1 = CustomIndicator1Name().Plot1[0];

Hi Tim:

I am having a bit of a problem calling the output of one indicator from another indicator. Here is the code I am using from my second indicator to call the output from my first indicator. The first indicator is called Ratio and it has a plot also called Ratio

double Spread = Ratio().Ratio[0];

I am getting the following error when I compile.

"No overload for method 'Ratio' takes '0' arguments" . The error code is CS1501.

Any ideas??

Thanks

Hi chisound,

Most indicators require arguments as well, for example, the Bollinger requires a standard deviation, and a period

double smatest = Bollinger(2, 14).Upper[0];

Once you type

double Spread = Ratio(

you will see the required arguments, and optional overloads.

It may be a little late to reply to this thread but earlier tonite I arrived here searching for the same thing and by way of example will post what finally worked for me in NT 7.

I wanted to use the D9ParticleOscillator rawtrend output series as input to another instance of the D9ParticleOscillator and finally discovered I could use Strategy Wizard to show me how to code it.

To make a longish story short the D9ParticleOscillator function looks like this with the rawtrend output series selected:

d9ParticleOscillator(Period, Phase).RawTrend

and the combined function like this:

d9ParticleOscillator(d9ParticleOscillator(Period, Phase).RawTrend, OuterPeriod, OuterPhase).RawTrend

In other words it appears that if an indicator is of the form

Indicator(parameter1,parameter2, ..., parameterN)

to use a data series "Indicator2_Series" other than the default (e.g., price) as input, the format is

Indicator(Indicator2_Series,parameter1,parameter2, ..., parameterN)
