Market Analyzer column for Indicators

[uacvax]

Hi,

In the NS Editor for MarketAnalyzerColumns there is no code to view for the "Indicator" column. How was this column programmed and achieved to have indicator and plot dropdown property menus?

I want to make the same drop down selectors in my custom NS files. Is this possible? Thanks.

Hello uacvax,

Thank you for writing in.

You can add drop down menus for properties in your scripts by utilizing enums.

More information about enums can be found here: http://www.dotnetperls.com/enum

I have provided an example script that shows how this can be done.

Please, let us know if we may be of further assistance.

Thanks Zachary. That is a nice example, however, I am looking for something more complex. There is something that NT is doing in the indicator column that allows it to pull in the full list of indicators into the drop down. Using enums would be hard coding items for the drop down whereas the indicators column in MA is somehow able to grab all the indicators dynamically.

Hello uacvax,

I apologize for the misunderstanding; I was thinking that you wanted an example of how to create a drop down menu for your properties.

I will be investigating this further to see how a list of indicators can be obtained.

Hello uacvax,

Thank you for your patience.

Here is undocumented code on how you can grab the collection of indicators:

Type[] availableIndicatorTypes = NinjaTrader.Core.Globals.AssemblyRegistry.GetDerivedTypes(typeof(IndicatorBase));
