Make indicator usable by strategy wizzard

[hongchen2000]

Hi,

I have some indicator that I want to use to build strategy using the strategy wizard. However, I can't see the indicator in the list.

I have access to the source code. Can I modify the source code to make the indicator usable by the strategy wizard? What do I need to do to make that happen?

Thanks,
Hong

Hello hongchen2000,

All custom and system indicators will be avaialble from the strategy wizard.

Can you see this indicator listed under Tools--> Edit NinjaScript--> Indicator?

Have you recently compiled your indicators? If you have not, please try compiling and then checking for this indicator in the Strategy Analyzer.

I can see the indicator under Tools--> Edit NinjaScript--> Indicator. I can also open it and edit it. I also click the compile button, as you suggested. However, I still can't see it in the "condition builder" when I try to edit a strategy.

Is there anything special that I need to do? I also try change the "browsable" for the dataSeries to true but no use.

I am new to NinjaScript. So maybe there is something obvious that need to set?

Thanks,
Hong

Hong,

Does this indicator show up from the chart if you right click on the chart--> select "Indicators"?

Does this indicator have any public plots?

Do you have any issues with any other custom indicators?

[hongchen2000]

Yes. This indicator show up from the chart if you right click on the chart--> select "Indicators"?

Yes. It has define some plots:


[Browsable(false), XmlIgnore] public DataSeries SellStopLine { get { return Values[0]; } } //Sell stop line
[Browsable(false), XmlIgnore] public DataSeries BuyStopLine { get { return Values[1]; } } //Buy stop line

Also, the data plots good on the chart and I can see its value in the info box.

Hong,

I tested that snippet and do not have any issues in a test indicator.

Is it possible that the indicator has another class name than the file name? The list will generate by classname rather than file name, so there could be a discrepancy here.

Please check the Public Class under the Description section around line 20

I just realize that the indicator was written for 6.5. I imported them into NT7 and they work fine, except not shown in the strategy condition builder.

Is that the reason it doesn't show? What do I need to do to make it shown?

I compare the code with other NT7 indicators and doesn't see obvious issues.

Does the indicator have a ChartOnly directive in the Initialize() method.

If so, comment it out.

The NS wrappers might need to get regenerated - would you mind attaching the file used here or sending to support so we could give it a run on our end for you?

Thanks,

[hongchen2000]

Yes. I think we hit it. I compare it to other indicators and it is missing the part that says:
#region NinjaScript generated code. Neither change nor remove.
// This namespace holds all indicators and is required. Do not change it.
....

How is that part generated by NS? Can I do it myself or I need to send the file to you to get it?

[hongchen2000]

I got it. I just recompile the code and it works now. Thanks a lot for the help.

Thanks for letting us know, glad to hear it.
