Using Lists

[CaptainAmericaXX]

Hello,
I'm attempting to use a List in an indicator, (List<double> Highs = new List<double>(); ) but I'm getting an error message, "The type or namespace name 'List could not be found). Can someone give me an example of how to use one within Ninja?
Thanks

Hello CaptainAmericaXX, and than you for your post.

If you include

using System.Collections.Generic;

in your using declarations, you will be able to use Lists. I would also recommend learning how to use NinjaTrader DataSeries objects, as these will work more in sync with Ninja's event handling and bar sequencing. I am providing a link to the Help Guide documentation on DataSeries.

Please let us know if there is any other way we can help.
