What is: using NinjaTrader.CQG.ProtoBuf?

[ClauTrade]

Hello,

I'm coding a strategy (Visual Studio Editor) and more times was occurring an error, today just when I was adding a simple code line (private Order tradeOrder = null;).

CS0104 'Order' is an ambiguous reference between 'NinjaTrader.Cbi.Order' and 'NinjaTrader.CQG.ProtoBuf.Order'

The editor was adding alone a Using declaration: using NinjaTrader.CQG.ProtoBuf;

Could you tell me why this occurs, exactly what is NinjaTrader.CQG.ProtoBuf and if is better to use it with CQG?

Please note that cancelling the declaration: using NinjaTrader.CQG.ProtoBuf; all back to work fine with no errors.

Many thanks. Regards

Hello ClauTrade,

NinjaTrader.CQG.ProtoBuf.Order is part of the connection adapter for CQG/Continuum connections.

The NinjaTrader.Cbi.Order is what should be used in your script.

VisualStudio is likely automatically adding using directives by guessing you will need it when typing a class name also used in other namespaces.

Note, the NinjaScript Editor does not do this.

Hello Chelsea,

yes, I supposed it was something from Visual Studio ... ok, I will stay using NinjaTrader.Cbi.Order and I will follow your suggest to avoid automatic adding.

many thanks for support!

Have nice day!
