Properties for second data set for indicator

[iq200]

Hi,
I want to use an alternative timeframe and/or bartype for an existing indicator. Are there some standard properties that I can somehow add to select the data from the indicator properties? I know how to use the datastream inside the indicator.I have seen this in other indicators..
Thank-you,
iq

Hello iq200,

Thank you for your post.

It is possible to set up a BarsType enum and a period enum property and pass these into AddDataSeries(). It is OK to do this if you add the strategy a chart, but it might not work if you try to optimize the strategy through the strategy analyzer.

The Spread indicator takes a string from the user to add the desired data series:

Take this same concept and add a BarsType selector and a period int.

This is how you will add a bars type selector:

[NinjaScriptProperty]
[TypeConverter(typeof(NinjaTrader.Gui.Tools.BarsPeriodTypeSelector))]
[Display(Name="Select BarsPeriodType", GroupName = "Parameters", Order = 0)]
public BarsPeriodType BarsPeriodTypeInput
{ get; set; }

Please let me know if I can assist further.

Actually Chris, this is not what I was looking for. The spread example seems to expect the secondary data to already be loaded and then one selects it.
I want to be able to select the data a bit like in the Data Series for where I type the symbol and period and to be able to select the bartype from a combo.
I have more sophisticated ways of taking in the information for a secondary data series in an indicator (no code available).

Hello iq,

Thanks for your reply.

I've attached a sample indicator that allows you to pick a secondary data series including the instrument, BarType, and period. Is this what you are looking for? Place the attached file within Documents\NinjaTrader 8\bin\Custom\Indicators then it can be edited and tested.

I look forward to hearing of your results.
