OrderFlowVWAP Indicator in Strategy

[Johnny90]

Hi NinjaTrader Team,

when I run the sample provided for the OrderflowVWAP indicator I get the error
"Non-invocable member 'OrderFlowVWAP' cannot be used like a method" in Visual Studio.

Sample:

Hope you can help,

Best regards,

Hello Johnny,

It might be something with VisualStudio not loading internal core classes.

Does the strategy compile in the NinjaScript Editor window made by NinjaTrader?

Hello Chelsea,

you're right. I can compile in NinjaScript Editor but then in backtest I dont get any results and I dont see a chart. When debugging with Visual Studio I get the following error:

An exception of type 'System.NullReferenceException' occurred in b422f52c9cb447f3ba73395a06885079.dll but was not handled in user code
Additional information: Object reference not set to an instance of an object

Inner Exception is also null.

Best regards,
Johnny

Hello Johnny,

Attached is an export of the sample code from the help guide copied and pasted into a script.

Note, that Order Flow+ requires a lifetime license key.

Hello Chelsea,

its working now. Thanks for you help.
Any idea on how to get rid of the error in VS?

Best regards,
Johnny

Hello Johnny,

Below is a link to a forum post where Jesse has mentioned temporarily including the NinjaTrader.Vendor.cs file will resolve the error.
