Hello,
I cannot understand why NT8 continues to say "BarsPeriodTime.Minute doesn't exist in current context" can you help me please?

Hello,

This is missing a using statement:

using NinjaTrader.Data;

You would need to add this to the top of the file.

In this case the sample lacked this namespace because AddDataSeries is not used. To find the default namespaces, you can generate a new indicator and they will all be listed at the top.


I look forward to being of further assistance.
