Using NinjaScript Editor for drop-down input data menu

[BIOK.NT]

Hi everyone!

I would like to create an strategy using NinjaScript Editor and I need to program a drop-down menu. How can I do that?

Thanks.

Hello BIOK.NT,

Thank you for your post.

If you want to display the drop down menu on the chart, it would require WPF modifications to an existing window. The example script from this forum post demonstrates adding a dropdown menu on a chart:

If you would like a drop down menu in the Properties window of your strategy, you can use an enum. Please see the example script from this forum post:

Please let me know if you have any other questions.

Hello Gaby,

Thank you so much for your quick and accurate response.

I have another inquire: How can I code in NinjaScript Editor a user configuring Moving Average (period, type of MA, time frame, etc) as an input parameter in a Strategy.

Once again, thank you for your support.

Hello BIOK.NT,

You can use an enum to select an indicator with logic.

Below is a link to an example.

You can add a int public variable as an input to supply the period.

However, for a different data series this has to be hard coded with AddDataSeries(), and the BarsArray[BarsInProgressIndex] or series (such as Closes[BarsInProgressIndex]) as the input series.

Hi everyone!
and is possible do a nested enum?

Hello,

We are not aware of any way to nest an enum using C#.
