Can Indicator add another Indicator to show on Chart?

[Shai Samuel]

I have developed and Indicator that call several other Indicators. For display purposes, the other Indicators (such as SMA & MACD), are needed to be added to the Chart. Since all of the parameters for all of the other Indicator, are included in my Indicator, it would be great, if there was a way to add these indicators to the Chart from my Indicator.

Is it possible?

Shai, that's an item on our feedback list for potential enhancement - however presently unfortunately only strategies could add indicators in for display purposes.

You will have to create new Plots and assign the Plots the values of the indicators.

Thanks Koganam.

- Can this be done from an Indicator?
- Can the new plot be assined a new panel?

[koganam]

Thanks Koganam.

- Can this be done from an Indicator? - Yes; Plots can only be drawn, natively, in indicators.
- Can the new plot be assined a new panel? - No. Indicator plots will be plotted on the panel on which the indicator is loaded.

Sorry for resurrecting this old thread, but ...

Many times in NT7 I have wished for this exact feature.

I want the ability for an indicator to Add() another indicator to
the chart (naturally the added indicator plots/displays on the chart)
and I want to access that added indicator object the same as I might
do inside strategy code.

I see that NT8 has AddChartIndicator() but this looks to be a method
reserved for use by strategies -- in fact, it's looks like nothing more
than the old Add() method renamed to AddChartIndicator().

Does NT8's NinjaScript support a method for an indicator to add
another indicator to the chart?

Ie, what's the current status of this thread's request with regards to NT8?

Hello,
I am unsure of what is meant by the following:

and I want to access that added indicator object the same as I might
do inside strategy code.

Could you please elaborate on your request? Please be thorough so I can write a feature request for you.

Hi,

Thank you ShawnB, for following up. G, this is a post from 2 years ago, when I had little experience, and so many water move under the bridge since...

Anyway, the reply I got from koganam, was sufficient.

The only addition I can think of, which is relevant in any case, with, our without additional indicators, is to choose a plot to show on a different panel, since plots might be of totally different value range (for example: one plot can be of value range of 1..-1, and another can be price range.

I understand this might be complicated, for the UI.

Sure. Inside Initialize() of an NT7 Strategy I can do,

  EMA ind = EMA(20);
  ind.CalculateOnBarClose = this.CalculateOnBarClose;
  ind.PaintPriceMarkers = false;
  ind.Plots[0].Pen.Color = Color.Red;
  ind.Plots[0].Pen.DashStyle = DashStyle.Dash;
  ind.Plots[0].Pen.Width = 1;
  ind.Name = string.Empty;
  Add(ind);

which adds the EMA indicator to the chart, along with some custom settings I may wish to make. If desired, I could also do,

  Add(EMA(20));
  Add(EMA(Median, 34));

But all this code is illegal in an NT7 Indicator, since an indicator's Initialize() cannot use Add() to add another indicator to the chart.

In other words, in NT7, the Indicator class did not support an overload for the Add() method that allowed other indicators to be programmatically added to a chart. The Strategy class in NT7 supports this, but the Indicator class in NT7 did not.

So, the question is, does NT8 allow an indicator's Initialize() to Add() another indicator?

Granted the method names "Initialize" and "Add" may have changed in NT8, but I presume you get my point.

Simple question.

Hello bltdavid,

The ability to add an indicator to your chart from a script is also limited to strategies in NT 8.
Use the AddChartIndicator() to add an indicator to the strategy only for the purpose of displaying it on a chart


I have included the ChartIndicators and AddChartIndicator() Help Guides to assist you further.

[bltdavid]

Ah, ok ... thanks.

Is there an feature request open to add this capability to NT8?

Hello bltdavid,

I have just submitted a feature request on your behalf. I will update this post with a id for this request if/when one is available.
