TheVwap_Intraday.Util.PeriodIterator

[designer01]

Why do I keep getting this "using" phrase after compiling in my strategies?

using static NinjaTrader.NinjaScript.Indicators.TheVwap_Intraday.Util.PeriodIterator;

Hello designer01,

Are you saying that information is being printed to the log or output window?

[designer01]

It comes up under the using at the top.

Hello designer01,

It looks like that would be based on how that indicator is coded. The type PeriodIterator is being referenced. To prevent that from happening the script which has PeriodIterator in it would need to be edited so that type is exposed correctly for whatever use case that is being used for.

[designer01]

This is the full code, I am not sure where the PeriodIterator is being referenced. If I comment the using lines as shown the code compiles and works fine. This has happened with other strategies as well. Weird!

Hello designer01,

The code being referenced in the using statement is part of the TheVwap_Intraday indicator, you would need to review how that indicator is coded in this situation. If extra using statements are being added to the strategy and they are coming from that indiciator you would have to review that indicators code to better understand why that's happening.

[designer01]

But I am not referencing TheVwap_Intraday indicator. That's why it's so weird.

[NinjaTrader_Jesse]

Hello designer01,

I understand that however the same answer applies here, the code being placed in the strategy comes from that indicator so you need to look at that indicator and how its coded. Alternatively you can delete that indicator to prevent that.
