The type or namespace name 'List' could not be found !!!

NT,

Ever since I upgraded from in 6.5 subversion 10 to 12, I have not been able to create a NEW indicator that uses the "LIST" directive.

Existing indicators do not have this problem.

Here is the code snippet with the problem.

private List<LadderRow> askRows = new List<LadderRow>();
private List<LadderRow> bidRows = new List<LadderRow>();

Is "List" still valid ???

Thanks,

RJay

Please be sure you are adding the necessary using statements. I believe you need System.Collections or something similar. Check your old scripts.

I believe it's System.Collections.Generic.

Lists are identical, just in a different sequence.


Old File that Works...

using NinjaTrader.Gui.Chart;
#endregion

I believe it's System.Collections.Generic.

This fixed it.
