Order Flow VWAP

[Wargos]

Hi all,


I.m trying to develop a strategy with the OrderFlowVWAP indicator. And i.m reading the documentation in the wiki:

https://ninjatrader.com/support/help...flow_vwap2.htm

But when i try the code on VISUAL STUDIO 2019 , it doesn.t work:

double VWAPValue = OrderFlowVWAP(VWAPResolution.Standard, TradingHours.String2TradingHours("CME US Index Futures RTH"), VWAPStandardDeviations.Three, 1, 2, 3).VWAP[0];

It doesn.t recognize the function "OrderFlowVWAP(.........)". How can i use this indicator ? I recently upgrade my license and i have a full life time license.


King regards,

Hello Wargos,

Thank you for the post.

What is the specific error that you are seeing?

I would otherwise suggest to attach the script you are using so that I can review the structure of the script and using statements. The indicator should be able to be used by using the sample from the help guide you linked to.

I look forward to being of further assistance.

The problem is that the code work when i use the NinjaScript Editor. But when i open the solution on Visual Studio, it doen.t recognice the line:

 
 double VWAPValue = OrderFlowVWAP(VWAPResolution.Standard, TradingHours.String2TradingHours("CME US Index Futures RTH"), VWAPStandardDeviations.Three, 1, 2, 3).VWAP[0];

Hello Wargos,

Thank you for clarifying that.

Visual studio does not have intellesense for this indicator as it is not included as source code so what you are seeing is correct. It will still compile it is just not able to pull that from the NinjaTrader custom project.

You can manually include the NinjaTrader.Vendor.cs file in the visual studio solution however it will be removed every time you make changes in the ninjascript project.

I look forward to being of further assistance.

I.m trying but still doesn.t compile on Visual Studio.The error i get is:

CS1955 C# Non-invocable member cannot be used like a method.

Hello Wargos,

Visual studio will not be able to compile in any use case, it is just being used as a text editor here. If the platform compiles in the NinjaScript editor then the syntax would be correct.

I look forward to being of further assistance.

That worked for me - hope I won't have to add it too many times - thanks

// This compiles in VS2022
// Will post back if it does not yield VWAP seies

var hours = "CME US Index Futures ETH";
var OFVWAP = new OrderFlowVWAP();
var VWAPObject = OFVWAP.OrderFlowVWAP(Input, VWAPResolution.Standard, TradingHours.String2TradingHours(hours), VWAPStandardDeviations.Three, 1, 2, 3);
PlotVWAP[0] = VWAPObject.VWAP[0];
